20 Feb 14 Reventador Volcano East of Quito currently ACTIVE and erupting.
WARNING - CURRENT ERUPTION IN EFFECT
Composing current news data from various sites.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014022012.gif contains the current seismic.
One can see that it is more dramatic than the outset of the eruption earlier in the month of the Tungurahua volcano south by Banos.

Reventador - background of the Volcano - current state - ERUPTING
(it is interesting that this volcano tripped into eruption as the other volcano which was erupting south of there, Tungurahua, started to quiet down - the question was where is the molten magma moving? Timing wise, the Reventador volcano activated about the same time as the Solar particle field from the previous CME and geomagnetic storm was reacting on Tungurahua)
Structure and eruptive history
Reventador volcano consists of three successive volcanic edifices (INECEL, 1988).
This is constituted as a Basal Volcanic Complex (CVB) and is a stratovolcano that began construction about 350 000 to 400 000 years before present (BP).
This building evoked a large sector collapse, which caused an eruption and debris avalanche deposit of approx. 20 km.
This event occurred estimated about 30 000 years BP.
Its emission products include volcanic lavas and andesitic and andesitic breccias and some basic lavas and pyroclastic deposits of more differentiated composition (andesites and rhyolites).
The intermediate volcano nearby, called Paleo Reventador Volcano (VPR), is also a stratovolcano.
The growth with a pyroclastic avalanche from the caldera directed towards the East, is easily recognizable in the current topography and avalanche deposit is estimated at 8 km.
The age of this event is estimated at 20 000 years BP.
The compositional range of volcanic products of this building is restricted to basic and intermediate components, (basalts, andesites and basic andesites ).
The primary cone, called Volcano Reventador (VER), is built into the latest avalanche caldera.
As for VPR building skywards, this presents as a restricted cone of volcanic products ranging from basic andesites and andesites range.

The current building (VER), is one of the most active volcanoes of the Ecuadorian arc, being especially active during the twentieth century.
Important activity has been reported in the 20's (1922, 1926, 1929), in 1936, in 1944, in the 50's (1955, 1958, 1960) and 70 (1972, 1973-1974 and 1976).
Of these periods deserve special attention eruptions 1944 (VEI ~ 3), in which an ashfall in Quito reported for 5 hours, and the eruption of 1976 (VEI ~ 2), which was observed and described by ML Hall (Hall, 1980).
During the historical periods of activity, the level of explosivity of these eruptions has been moderate (VEI 2-3), with an eruptive dynamism that can be classified as Strombolian or Vulcan.
Volcanic phenomena generally were recognized during these eruptions with moderate ash falls in the Sierra, with pyroclastic flows and lava flows around the cone and mud and debris flows (Lahars) that fell by the rivers.
A little bit of video when there was just some small activity last November. No spectacular eruption in this video..

Speaking of Ecuadorian eruptions, here`s a pic of Tungurahua as it erupted this morning, taken as we flew past at 35 000 feet. The plume quickly reached our altitude, but by then we were past it and descending into Quito. Timing is everything!

Historic since the 17th Feb 2014 - Reventador has been becoming active ALSO as I had been pointing out with Tungurahua (further south) in Ecuador at about the same time period windows as the solar particle storm influx hitting the earth when the Sun approximated ZENITH (overhead).
Starting with the 17th, note the time local

In the Tungurahua thread I had pointed out the seismographic system was experiencing an offset skew (similar to a change in the magnetics, creating a local shift of baseline), see image, http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014022012.gif and in the above image at the Reventador seismic system over 100 miles away.. see the local time from 1400-1500 hours in the two graphics to see the similar type of offset. It is believed that the geomagnetic storm (solar induced) was creating this energetic activity..

Sorry, Bobd, I cannot report on Quito. As soon as arrived at the airport, we hopped into a taxi to get us to a bus pickup for Tena, which is where I am now. Tena is about four hours by bus, E/SE of Quito, on the Amazon basin side of the Andes.
I'll keep my eye on the sky for the next few days, though! This country is full of surprises!

25th February 2014 - ACTIVE
Reventador in Ecuador is erupting and the pattern is tracking the solar zenith - see below

Solar activity
X-FLARE! Long-lived sunspot AR1967 returned to the Earthside of the sun on Feb. 25th and promptly erupted, producing an X4.9-class solar flare. This is the strongest flare of the year so far and one of the strongest of the current solar cycle. It was not earth facing though.
http://spaceweather.com/images2014/25feb14/coronalhole_sdo_blank.jpg?PHPSESSID=ccna29immkadb3vf3b88kb3144
Squarely facing the Earth, the coronal hole continued to eject solar particles earthward.

Reventador in Ecuador continues to Erupt
The event of eruption is still corresponding to the solar zenith. Today an apparent geomagnetic offset caused a skew repeatedly in the seismic recording in a few placed during the eruption periods (see below)

Hia Seehas - nice to touch base, I watch your posts too with enjoyment :) very well done !
if you could keep an eye on Reventador.. What is specifically very interesting is the tracking when the sun starts to get near 10:00 local time, the volcano starts to peak, as shown in the seismic - not sure how to determine the ground shakes closer to Quito..
My friends near Tungurahua when they were at altitude, on the high plains, did have ash issues, and sulfur dioxide (choking) gas issues.. When Tungurahua calmed down, the northern volcano(s) started to get active, all the way up into Columbia.
I'm following Mitch Battros' theory that solar particle storms can trigger/evoke volcanic eruption and earthquakes, and so far as I can tell, it is tracking.

Like clockwork Reventador, Ecuador, is erupting starting about when the solar zenith starts to approach and the particle stream causes the magma to activate.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014022712.gif
I took a brief look at Tungurahua down by Banos and there are slight increases in the spike, and a very small eruption event.
Solar activity shows:
"CME IMPACT TRIGGERS GEOMAGNETIC STORM: A moderate G2-class geomagnetic storm is in progress following the glancing impact of a CME on Feb. 27th at 1645 UT. Sky watchers in Europe are reporting bright auroras. Ruslans Merzlakovs sends this picture from Nykøbing Mors, Denmark:"
There is a coronal hole also squarely earthfacing.

Expect increased volcanic and earthquake activity.
Auroral activity was seen in Denmark
http://spaceweather.com/images2014/27feb14/denmark_strip.jpg
Reventador was erupting a little earlier today and continued a bit into the evening a bit longer. 28 Feb 2014
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014022812.gif
As to the volcano to the south, Tungurahua, I have never seen this type of seismic activity. A type of eruption was happening without intense magma evolution.
(Showing Tungurahua here for reference comparison).
http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014022812.gif
Looking at the two seismic graphics, we can see even though the over 100 miles differences in locations, the timing of the activity started about the same time.
Solar activity continued to stream particles from the coronal holes which are still earth facing.

Taken by Francis Anderson on February 28, 2014 @ About 4km just outside Tuktoyaktuk, Northwest Territories Canada on the arctic ocean
Reventador continually erupting since last nite. 1 March 2014
The volcano started earlier yesterday morning, in its eruption cycle and continued with increasing seismic activity throughout the nite. This is tracking the solar particle storm activity that was predicted earlier in the week from the CME's, geomagnetic unsettled events, and coronal holes.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030100.gif
7pm local time Ecuador, on wards showed strong activity
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030112.gif
Above is the daytime activity showing strong rumbling, magmatic activity, and eruption
Tungurahua to the south (Banos) only showed a brief spiking in seismic activity as the solar zenith started to approach, although there is no current eruption showing.
Earth's polar magnetic field is still glowing with auroras following the CME impact of Feb. 27th although there is some diminishment.
http://spaceweather.com/images2014/01mar14/coronalhole_sdo_blank.jpg?PHPSESSID=l19gkdob49g60fncrj0n1a8k26
Coronal holes currently are diminished, and residual heating is slowly subsiding. Class "M" flare activity is 70% probable in the next two days.
Reventador volcano Ecuador is having an unusual eruption and seismic cycle - showing up today and last nite, as having had periods of long term eruption, then moderate seismic activity, then almost zero activity during the wee hours, and then intense regular "rumbling" without obvious eruption.
Is this unsettled activity, or finally is it calming down? We'll track this for a few more days to see, taking a look at the other of the two "erupting" volcanoes in Ecuador (as according to their geological institute).
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030200.gif
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030212.gif
As seen in the second seismic graphic above, the strange period of total calm was punctuated with a few small blasts, then the rumbling starts..
http://spaceweather.com/images2014/02mar14/coronalhole_sdo_blank.jpg?PHPSESSID=06da4ugueumnloap82jtt6oiq2
There are no direct earth-facing coronal holes present, and there is winding down of particle streams from the previous events. Prediction from NOAA is that there still is a potential for M Class flares (70% possibility).

Auroral activity was diminished
Reventador remained unsettled, and active through out the night as seen in this seismic chart below - 3 March 14
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030300.gif
As Solar Zenith approached, activity increased with a rapid series of seismic spikes (sharp bursts of energy release), then generally the activity of magma movement increased.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030312.gif
Coronal Holes are starting to form and move into Earth Facing position, which if tracking indicates what has happened previously monitoring this effect, there should be an increase in volcanic activity in the next couple days from the volcano when solar zenith approaches.
http://spaceweather.com/images2014/03mar14/coronalhole_sdo_blank.jpg?PHPSESSID=9cujui2136trej2390ko0ajm06
Reventador 4 March 14 - seismic equipment went offline in Ecuador last nite and didn't come back online until 0100 local time.
After coming up, the seismic activity showed nil activity.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030400.gif
Morning afternoon seismic graphics shows nil activity.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030412.gif
The sudden cessation of Reventador is unusual, considering the dome growth report of the Tungurahua volcano matches the similar pattern (cessation of activity without gradual diminishment) we see here with Reventador. This will be watched to see if this is a temporary cessation, or if a cap rupture potential is indicated. If magma solidifies, it forms a growing mass, can act like a cap, trapping gases within, eventually leading to a catestrophic large explosive event (as is seen in stratovolcanoes around the world, i.e. Krakatoa Sumatra was the explosion "heard round the world" paraphrasing a bit (http://www.livescience.com/28186-krakatoa.html).)
EDIT UPDATE: - at about 1430 intense rumbling resumed, with no explosive event. Watch this closely as well as the GuaGua Pichincha to the west.
Reventador volcano, Ecuador 5 Mar 14 - no activity - no eruption activity - this is unusual.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030512.gif
Where is the magma?
Reventador, volcano Ecuador came back to life today (as well as tungurahua) 6 March 2014
The previous night and early morning was quiet showing no indication that any activity was about to happen. This is unusual, indicating that there may have been a plug forming preventing the releases of small amounts of gas and ash. Possibly the small spikes are indicative of small fractures releasing..
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030600.gif
About 1230 local time, sustained continual eruption after a period of quiet was occurring.

http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014030712.gif
Eruption activity started earlier today, at about 0800 AM local time and continued for a 5 hour eruption almost constantly until 1300 hours local time.
POST UPDATE - after about a break of an hour, Reventador continued constant eruption activity. (See the seismic graphic above for the time/duration events)
Reventador continued erupting until about 2215 local on the 7th then for today, the 8th March 14
resumed moderate activity, picking up in intensity, about 1800 local time.

Reventador - Ecuador - 12/13 March 14
Seismic monitoring network went off-line and remained off-line until about 1930 local time Ecuador (13 March 14).
Key volcanoes were not being monitored due to the data-outage.
Reports have now resumed.
The last available report before the network outage was:

Reventador today, continued its crazy very high frequency spikey seismic activity. Good to see the seismic reporting network monitoring once again these volcanoes in Ecuador - the network was down 12 March 14 from about 1430 through 13 March 14 1900 hours local
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014031412.gif
we'll update the report later this evening as things progress.
Geomagnetic activity is relatively quiet, and the eruption pattern apparently is showing no major eruption activity. Earlier in the week there was some high intensity X-ray ionization in the earth upper atmosphere leading to aurora activity, and a surge in eruption activity (see post 25 above).
Ed Note - shortly before 1600 hours local time, notice that there was a small but sustained seismic rumble.. two other volcanoes, GuaGua Pichincha and CotoPaxi both about the same time started experiencing seismic volcanic events. CotoPaxi by far had the larger of the two.
Reventador picked up eruption activity later in the day once again, after a period of quiet from early morning activity.

Reventador for 16 March 14 seismic activity
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014031612.gif
Significant - the event that was starting at 1025 am local time was 2 minutes prior to the events at CotoPaxi and Tungurahua, and 13 minutes after the event at GuaGua Pichincha, possibly showing that the magma river in this arc chain of volcanoes had the impulse start in the upper North-Northwest and traveled eastward, and then southwards to the other volcanoes. Never-the-less this connection is showing that a common feed system exists - the obviousness is that, these volcanoes do not make up just separate small volcanoes, but possibly the total magma volume that is feeding these are actually a "super-volcano".
Will a massive event happen, unknown at this time what triggers a massive event simultaneously, except that the plate system that is generating the heat, could massively slip/compress resulting in a large release of the fluidic rock.

Reventador - 17 March 14 - seismic report
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014031700.gif
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014031712.gif
SIGNIFICANT - at about midnight a significant event occurred, and about 20 minutes later. This tracked exactly with the CotoPaxi Volcano, and the Tungurahua volcanoes to the south. This shows a common magma system exists, and demarks part of the size of the potential "supervolcano" perimeter of Ecuador's northern Andes active volcanic range. There is no understanding at this time, on how much magma is present, which is a requirement to determine the potential size of a potential supervolcano eruption, nor what triggers such events.
The determining factors could be "plate stresses" which could slip radically and dramatically, squeezing melted rock through the channel systems, and of course how much melt is present in such chambers. What is significant is that we are seeing simultaneously timed events happening, indicating that the driving plate structure is pulsing at the same time or within moments or minutes of each other, and that these volcanoes are separated by a vast distance.
The ring of fire region on the eastern side has been experiencing large seismic events in the last few days from northern California, off Baha Mexico, within Columbia, off Ecuador, off Peru, and off Chile.. and we have been seeing increased activity in relatively calm volanoes, and volcanoes which are normally erupting have changed their patterns and cycles.

Reventador - Ecuador - seismic and volcanic activity - status intermittent eruptions, unsettled activity, large rumbling continues 25 March 14
Reventador continues to do it's job to be the "escape valve" for the northern chain of the Andes volcanic arc in Ecuador, letting off what amounts to immense pressures from the magma river deep below the surface.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014032500.gif
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014032512.gif
With this much activity, when things move to totally SILENT, one would be very concerned as there would be either a diversion of the magma river, or there has been a massive plug that formed (or plugs).
It is important to watch the volcanic chain from Chile, northwards thru Peru, Ecuador, and Colombia to understand what is happening on-shore with volcanic activity, or offshore with large deep earthquakes - such are events on the eastern side of the Ring of Fire - which leads all the way up the coastal ranges, all the way up to Alaska (through Canada's Vancouver Island, Washington/Oregon, California, Mexico, Pan/Central America)..
The heat has to go somewhere, and it converts through magma flow, into lava and eruptions. It's a balance and things have to continually operate properly to keep extremely large catastrophic events from happening.
The 14th and 15th of March was particularly worrisome when activity stopped and went totally quiet.. Later on the 15th this corrected with whatever was stuck letting loose, and Reventador acted like a pop bottle being shaken, releasing a lot of fiz and liquid.
Imagine a steam radiator, with a relief valve which must remain open when certain pressure levels are reached. If that pressure isn't gradually released, if the pressure relief valve gets stuck, blocked or frozen, the boiler down below continues to heat up, and pressurize the system.. Eventually if not corrected the pipe breaks, and something really nasty could happen. That's why the flow needs to be balanced and stable..

Reventador continued its multi-day erupting until about 0600 when it slowed down, to a minute eruption, a minute off, a minute eruption - then it slowed down to about a 2 minute gap between eruptions.
There have been quakes up and down the coasts of S. America and up into California.

There was a network outage of the server at the University yesterday, preventing the graphic pages from loading.
As anticipated, when Reventador slows down its erupting, the other volcanoes in the region should pick up activity - Checking CotoPaxi, about 50 miles away there has been increasing activity. Tungurahua, about 110 miles away did not show any activity or tracking (which is odd). It appears then that the southern volcanoes are slowing in output, while the northern volcanoes are showing increasing activity. GuaGua Pichincha showed a LOT of activity during the night and morning.

Reventador - volcano - Ecuador - seismic and volcanic activity - 31 March 2014
The volcano during the night continued with its erupting, but with shorter bursts a brief calm, then some longer sustained bursts.. Reminds me of a drain hose hooked up to a pump that has been sucking up debris, when the denser chunks are present, the flow slows down, then loosens up and a lot of flow comes out, then slows down, then picks up.. Looking at the graphics one can imagine something like that seeing the patterns change over time..

Reventador - volcano Ecuador - Seismic and Volcanic Activity - 1 April 2014
There was a server outage until 2200 last nite, however after the connection was restored, it was noted that there were a series of very brief short bursts, similar to the CotoPaxi and G. Pichincha volcanoes. It is unknown if that was a data-error from the recording seismic channel, or if activity had actually stopped and the recording real. IF the recording is real, this is significant, that the volcano went silent..
We are waiting on a potential CME reaching the earth from an event from Saturday (x-ray flare), which supposedly will glance, or hit starting about 11:30ish pm 1 April and continuing through the 2nd April.. If that happens, there may be increased activity, and we will note it one way or another..
The volcano is strangely dropping in eruptive and seismic output.. generally when that happens when activity has been "high" either the volcano has emptied it's magma channels, or something is being plugged up. If plugged up the tilt-meters would show tilting when the cone and ground changes shape. The Geological Institute which provides these graphics is watching the tiltmeters and will report if there is substantial tilting on a report on their main page.
Activity started to resume shortly after 0400 am with about a minute eruptive bursts and then a lot of rumbling, and lesser and lesser duration bursts.. Between 0700 and 0800 there was a flare of activity, then calming once again.. A little bit of activity between 0900 and 1000 and then a lot of calming and some ash slide activity.. This IS unusual..

Reventador - volcano Ecuador- Seismic Event from Chile - 1 April 14
The volcano started to peter out, starting about 1600 and then after one small blast, all activity stopped. This is very strange. This volcano is quite far north and east of Reventador. Very slight seismic activity was indicated from the Chilean 8.0 which at 1852 local time. It continued to show harmonic ringing (very slightly) until 1909 local.

http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014040200.gif
It could be possible that the precursor to the Chilean quake was showing up in a change of the volcanic MAGMA system that feeds Reventador, and that there is not a large plug that formed that stopped the pressure relief output.. KEEP a watch on this volcano to start up "normally" to continue to act as the pressure relief valve for the Northern Andes volcanic arc chain..

The eruption periods of Reventador have changed since the Chilean 8.2 quake of 1 April. The Geological Institute says they are monitoring the volcano for any substantial change in patterns.
"Seismic activity of the volcano is Reventador at high levels since March 25, as mentioned in Special Report issued on 26 of this. In recent times, this has increased and is characterized by the presence of a continuous simian tremor with few breaks and so far manifested steadily CONE station located in the north-eastern flank of the cone ( Figure 1). This activity is consistent with the visual observations of the volcano and have corroborated the presence of surface manifestations almost continuous emission material."
"Superficially it was possible to observe a continuous emission of gases with variable ash content whose address has changed between the north-west and south-west. It has been observed through the visible and thermal cameras range (infrared), generating secondary pyroclastic flows, related to the partial collapse of the dome which is continuously growing inside the crater since 2011. These flows have fallen by the eastern flank, south-eastern and south; walking distances up to 1.5 km from the summit. Additionally there have been at least two lava flows descend the south eastern and eastern flank of the volcano, whose fronts are approximately 500 m below the summit level. The detail of this information can be seen in Figure 2, in which a superposition of a thermal image is displayed and visible range of the eastern sector of the volcano."

Reventador - volcano, Ecuador, seismic and volcanic eruption report 4/5 April 2014
the volcano radically changed its eruption pattern since the big 8.2 Chilean quake of 1 April 2014..
As of today and last nite, there have been about up to 1 hour gaps between eruptions, and eruption periods have not been consistent in duration. For example 6 minutes eruption, 45 minutes calm, 4 minutes eruption 10 minutes calm, 45 minutes eruption 2 minutes calm - very varied, no longer a calm regular "venting" of the magma river from down below.. The other 3 volcanoes, Tungurahua (erupting), CotoPaxi (showing explosions), and G. Pichincha (showing explosions) are showing increased activity.

The volcano continues to exhibit strong hour long eruptive periods interspersed with very quiet periods, and periods of strong rumbling.. This is somewhat similar to the currently erupting volcano to the south Tungurahua about 110 miles away. Both volcanoes in the middle of that range, CotoPaxi and G. Pichincha are exhibiting increases in activity during unique parts of the day and night.. There is no clear indication if those other volcanoes are experiencing any magma buildup in their domes or magma channels.

Tungurahua the other volcano to the south in Ecuador was highly diminished in output with hardly any eruption. The other two volcanos being monitored in these threads, are showing more "volcanic like activity" is becoming obvious than simply remaining quiet and asleep. No direct indication is showing up at the moment, despite some periods of minor harmonic tremor in those other volcanoes earlier in the week.

Reventador, volcano Ecuador, seismic and volcanic activity 16 April 14
Yesterday afternoon the activity continued to reduce, almost 5 hours without a serious major eruption. It almost seemed like Tungurahua to the south when it's period of eruptions were stopping. However during the evening, closer to 22-2300 local time, the volcano lit up quite strongly. That continued until about 0400 am then the output changed to a roar interspersed with a 3 minute eruption blast now and then.
The intense roar rumble continued strongly without a major burst until about 1800 when some more normal in strength puffs occurred. The roar continued into the later hours, with a puff burst now and then and was continuing that pattern, 30 second bursts up till shortly after midnight when this report was written. It is definitely a change in behavior for the volcano.

Reventador, volcano Ecuador - volcanic and seismic activity - STATUS CALM (very unusual), occasional puff/event 18 April 14
The volcanic activity has subsided immensely, and this is very unusual for Ecuador's most continually active volcano. Where has the magma river moved to? After the large >+8 magnitude Chilean quake which rocked the region, volcanic activity in Ecuador changed and continues to show changes in seismic patterns. The CotoPaxi Volcano and the GuaGua Pichincha volcano have continued to increase in seismic activity, while, both Reventador and Tungurahu are changing the eruption patterns to less dramatic outbursts.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014041800.gif
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014041812.gif
A couple bursts near 0200 am last nite corresponded synchronously with similar activity down by Tungurahua volcano to the south about 115 miles away. This is showing apparently that the earlier CotoPaxi linking about 50 miles away previously (which was showing linking activity with Tungurahua) now extends further northwards to Reventador (that does show that a supervolcano magma structure potentially exists, but as with any supervolcano, the amount of melted rock (magma) and gases has to be sufficiently large to present a larger danger of simultaneous massive eruption.
The volcanoes in the heated region of this volcanic arc provide a relief from the heat, from the pressure of the magma.. The river system (magma molten), periodically relieves itself to the surface in the form of gases, lava and ash eruptions. IF that stops for any period of time, that heat still exists, and will continue to melt rock increasing the size of the magma pocket (or domes). This is one of the factors to be looked at, having eruptions stop for any length of time really is not a good thing, as pressure can build, and massive amounts of magma can build-up.
The Geological Institute in Ecuador is monitoring for this magma buildup, and have commented that Tungurahua (to the south of Reventador), although the constant eruptions have diminished, magma IS building up deep, at least a mile below the surface, and they are concerned about explosive eruptions in the upcoming weeks.

Reventador Ecuador volcano - volcanic and seismic activity - 23 April 14
The volcano was strangely quiet, with 6 explosive events, and no appreciable eruption. This is a bit worrisome, where is the magma, where is it building up, what is clogging up the channels? After the April 1 Chilean large 8.2 quake, the plumbing system all up and down the ring of fire, the eastern side has been changing. Older quieter volcanoes have been picking up activity, the existing erupting ones have changed their eruptive pattern.

Instead of seeing INcreased activity, overall we have been seeing DEcreased activity with Ecuador's two most active volcanoes. Hard to say though as there appears to be a cycle appearing where during "quiet" periods, lasting 1-3 days, they are followed by a flurry of continual explosive, eruptive activity. That would be coincident with the magma freezing/thawing having to melt different new fresh rock due to the slides/slips of the regional deep faults. However we have been seeing increased activity with G. Pichincha, and CotoPaxi. Where is the magma is the question..

Reventador Ecuador volcano - volcanic and seismic activity - 24 April 14
The volcano started to come back to life shortly after 1500 yesterday afternoon with a moderate eruption.

http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014042412.gif
Closer to 2000 hours local, the volcano switched to continual eruption up till about 0800 this morning, and started to diminish in eruptive output. As of 0945 eruptive periods were diminished to a minute to a minute and a half, with roaring. What was interesting to watch was how when the volcanic activity dramatically decreased over the previous days, (and the magma obviously cooled and/or solidified to an extent, plugging up the plumbing so to speak) then the subsequent melt and replenishment of the magma in the channels resumed with intense pressure release showing continuous eruption.

Reventador Ecuador volcano - volcanic and seismic activity - 26 April 14
The volcano slightly had diminished activity today, mostly with a LOT of roaring and some outbursts. This pattern of less output has been present since the April 1 14 8.2m earthquake in Chile which appears to have shifted some of the faults and magma sources.

Reventador Volcano Ecuador volcanic and seismic activity 28 April 14
The volcano started roaring shortly before 2000 last nite for about two hours then calmed down, and started up with a fierce eruption sequence close to 0200 am local time. There was a pause for about an hour and again there was a period of 2 hours of eruption, very strongly presenting.

http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014042812.gif
Shortly before 1100 local time this morning after periods of relative calm, there was a sustained 20 minute eruption peaking about at the 10 minute interval.
There appears to be a day long "SLOW WAVE" with the eruption pattern, which could be indicative of a larger deeper magmatic surging occurring in the region, something like a slow sloshing up and down the Ring of Fire, from Chile northwards (thru Ecuador), up the PanAmerican region, up the coast of Mexico, the US, and over to Alaska then down to Japan and towards Indonesia. It could be like a slow pulse traveling, like a wave in that plate channel, a wave in a river so to speak.. Watching for this could show were the next series of eruptions would occur.

The volcano was emitting less activity yesterday evening into the early morning hours. Average eruption time is about 1-2 minutes, with periods of sustained roaring. "Event" total period duration time appears to be about 30 minutes (instead of the hour long durations previously noted).

Reventador Ecuador Volcano - volcanic and seismic activity - 30 April 14
The volcano started to quiet down yesterday, a pattern we have seen, which might change in a day and a half (a low frequency surge cycle of the magma river possibly). The events last nite and this morning are marked by periods of eruption for 1 1/2 minutes in duration on average, 4 eruptions per hour, a bit less in event timing than Tungurahua to the south.

That there are no major continuous hour long eruptions is interesting too. We will see if the slow period cycle picks up.
Reventador Ecuador Volcano - volcanic and seismic activity - 1 May 14
The volcano started back up with long periods of eruption, up to an hour at a time, making up for the previous days minimal activity. There appears to be a pattern in the magma refill rate for the underground river or feeder channel.

Activity has been clearly reduced, with periods of calmer (activity remains) moments, with 1 hour and 3 hour eruptive periods. There has been a change obvious between the April 1, 14 Chilean 8.2m seismic event and May 1.. patterns of eruption and periods of calm have been altered.
Reventador Ecuador Volcano - activity 3 May 14
The volcano continued to oscillate between calm with periods of eruption, 10 minutes long continual, 1 1/2 minutes long, and up to an hour long. Periods of roaring marked the silence between ash/gas lava near the cone tip.

It appears that the slowing down of the emission is again occurring. Last nite a 2 hour period of moderate eruption was marked an hour later with periods of only 5 minutes, 4 minutes and 1 minute with a 3 hour calm period punctuated with only one puff a little after 0700 local time. The noise level is high, showing vibration is present, and a rumbling started up shortly before 0900 and changed to a visible eruption by 0915. A stronger roaring and some emission started up closer to 1030 local time, and is continuing as of the writing of this post.

Yesterday evening about 1720 it looked like the seismometer network developed recording difficulties for this channel. Shortly before 0600 am it appeared that activity was present, recording massive activity from the Volcano which continued until shortly after 0700 am local time (1 hour period of eruption).
1030 marked another 1 hour period of eruption, followed by some massive magmatic explosions (about 1 minute apiece) close to 1230 local time. Roaring and roiling continued up until after about 1830. Another period of events started up with an eruption about an hour later and was still continuing as of the time of this post.

The seismic sensor appeared to go off-line yesterday about 1300 hours and appears to be offline. If the volcano actually damaged the sensor, that is possible, emission could be still happening, the IR sensor camera is shown after the graphics, if any activity is present such would show up here, unless the whole monitoring station is down. If the volcano actually stopped emission that would be a serious matter. We will watch this to see what is happening.

it looks like the seismometer connection dropped out shortly before 1900 hours local time, and noticing that the IR camera is still off-line. There may be a power problem or radio link problem on the volcano or something else happening with monitoring. No notices have been put up on the website at the institute explaining the difficulty.
Reventador Ecuador Volcano - activity 13 May 14
The seismographic system appeared to come back on line about 1020 this morning, after a long period of intermittent activity.
At the time of reactivation, very large rumbling roaring was indicated but no appreciable seismic events indicating active magma.
http://correo.igepn.edu.ec/heli/heli/CONE_SHZ_EC_--.2014051312.gif
The IR camera trained on the cone/volcano is not showing any thermal activity at the cone, which does then match the no eruption activity showing up in the seismic sensor readouts.
When the volcano stops its eruption for long periods of time, that pressure builds up and has to be relieved somewhere. There are numerous volcanoes in the region with activity appearing in volcanoes which normally are quite docile. Following the underground magma is interesting, watching and following the earthquakes up and down the ring of fire is very informative.
The CHILES thread in NEWS and UPDATES has a discussion about new activity in the region.
There was a recent large earthquake in PANAMA, also along the ring of fire, and this does correspond with activity being seen with the oscillating pulse train up and down the ring of fire.
(Note UPDATE - the IR camera is now showing lava flow on the sides of the cone)

Reventador Ecuador volcano 14 May 14 activity
The seismic system sending unit has still been having difficulty from the volcano. I did a capture of a very interesting event from the IR camera where one can see a large fireball being thrown out of the volcano.
The roaring surging is present currently with the emission from Reventador, but it has been reduced slightly from couple days. This volcano acts like a pressure relief, so it's emission is essential to prevent other volcanoes from erupting within close proximity. Tungurahua to the south is totally quiet, plugged up possibly. The other volcanoes to the north have been picking up activity, and Reventador has been diminishing activity.. Where is the magma? Chiles volcano up north towards the border is showing intense spikey quakey activity, and low and short wave seismic events of long duration (same is Cotopaxi showing periods of slow )(long) and short duration seismic sustained activity).

Reventador Ecuador Volcano - activity 18 May 14
Activity seems a bit less with Reventador, the "safety valve" for the region, and the other active erupting status volcano Tungurahua seems nil in output. Overall, GuaGua Pichincha, and CotoPaxi volcanoes which haven't had significant activity appear to be increasing in rumbling, seismic events, all indicative of magma movement underground. Will the magma break thu is yet to be determined.

Although still erupting, there is a period of diminishment in output compared to early prior to the April 1 2014 8.2m Chilean quake. There still remains a 1 1/2 day slow wave oscillation, that should be showing up in the magma channels, and quite possibly is traveling up and down the ring of fire zone. This volcano thankfully remains as a safety relief valve keeping output up to release the underground stresses. When this volcano stops activity, the magma builds somewhere, depending on the pulse circulation, the solar particle influx, we could see additional eruptions or quakes. This dynamic pattern being watched sufficiently over a long enough period of time is showing these patterns, and could help with predictability.

The morning of the 26th was very quiet proportionately to the other days. The 1 1/2 day activity cycle appears to be present, but output still is reduced, so the question is, where has the magma moved to in the region?
