"The volcano has erupted, now all the discovery channel shows fearmongering comes to mind, but there it is... it's possible... right now not "likely", but it's possible for sure.

We are between "possible" and "likely", we are between a "watch" and a "warning". We're between "don't worry" and SHTF.

Video of the large volcanic fissuring taking place here: https://www.youtube.com/watch?v=sEpWY...

If a Tsunami happens the buoys won't be helping, since there are none in the location or anywhere across the Atlantic until the coast of the USA directly , smh https://www.ndbc.noaa.gov/

I suppose if the island fractures and falls into the Atlantic, the government might tell us on https://tsunami.gov

"The video is the nice way of reminding everyone what I said earlier this week.

What I WANTED to say was: Settle the heck down. I told you earlier this week the intrusions were small so far - and if they get bigger we can worry about the tsunami risk. Yes, harmonic tremor swarms approaching the surface means a volcano may erupt... but the size of the quakes tells you a lot.

Yes, we will continue to monitor her, but the quakes are dying down, and until they go up to higher magnitudes the FEAR over this volcano this is overkill."

Could the plume of smoke at about the 46 second mark, and that we see in the still photo, satisfy the conditions the remote viewers say they foresaw in September?

That's what I think, see this post (<---)

[pyrangello]

So my st helens as I recall just built up pressure before it blew, this one is spewing the pressure out , now the trump cards are the steam in the rock being created and the excess weight of the lava on top of the land that is unstable ? I'm just throwing this out there , I don't know squat about geology? Unless the quakes start to build larger on the scale because it not relieving enough pressure.

Explosive eruption are dependent on the "acidity" of the lava (i.e., silica content)... in the Canaries, the lava is close to basaltic, very fluid and effusive, much like Hawaii or Iceland, rather than explosive.

[Ascension]

In 1958, a landslide in Lituya Bay, Alaska caused what is thought to be the highest tsunami wave in recorded history, 1720 feet high. It was tempered by surrounding geographic features and did not have the impact that an unobstructed wave could have caused.

It was a 90 million ton displacement.

The El Hierro rock (the one that could theoretically be dislodged here) is 500 km³ in volume, 25 km long, 15 km wide, and 1400 m thick. (That's a BIG rock.)

If the rock is volcanic, then it weighs something like 3500 kg/m³. So that means the whole thing would weigh a mind-boggling 500 x 3500 x 1000 x 1000 x 1000 kg. Check my work, but I calculate that to be about 1.75 trillion tons.

Er, I am confused, El Hierro is a different island to La Palma, and hasn’t been mentioned in msm relative to eruption.
Our olde “tirelessly” thread was about El Hierro, not La Palma. However, it’s all a wee bit of a dodgy situation at the moment, so hopefully nothing drops off any island !

You're 100% right, and my apologies. Here's a map:

Etna volcano (Italy): new paroxysm from SE crater sends tall ash plume to 9,000 m altitude

After little more than 3 weeks of calm, the volcano has again produced a violent lava fountaining episode, known as paroxysm, from its SE crater this morning:
At 4.20 a.m. local time, volcanic tremor suddenly began to rise sharply. At 8.15 a.m., ash emissions were seen from the New SE crater, and strombolian explosions started a7 8.55 a.m., generating an ash plume that quickly rose to 4,500 m altitude.
This activity continued to increase, and by 9.55 a.m. resulted in lava fountaining that generated a tall column reaching approx. 9,000 m height and drifting to the ENE. At the time of this update, the activity is still going on, but seems to be reaching its end as tremor started to descend again.
As during the previous paroxysms, a lava flow is traveling from the southern rim of the crater towards the SW.

Wonder what other volcanoes are happening

LA PALMA UPDATE: MORE EARTHQUAKES OVER NIGHT, ERUPTION CONTINUES, 166 BUILDINGS NOW GONE


Days after the eruption of the volcano, the earth continues to shake and last night a quake of 3.8 degrees shook the ground and opened the 9th ‘mouth’ of the volcano for lava to spill from. This was followed by another earthquake of 4.1 degrees early this morning in the area of El Paso, and another of 3.2 degrees just after 6am. It has also been announced that the maritime exclusion zone is being expanded from two to three kilometres around La Palma due to the danger of the volcanic eruption.

It is all the way on the far EASTERN side of the island. The fact that the ground is now sinking along the eastern coastline is indicative that a tear is forming at that part of the island. If the island tears apart, the ramifications for an Atlantic Tsunami grow exponentially. ( combine this with the higher quakes in the last 24 hours and were having a perfect cocktail being made, and yes the temperature of the lava is increasing as well)

UPDATE 12:21 PM EDT --

New readings from the Satellite-enabled GPS instruments at the far south of the island of LaPalma show that the lift CONTINUES despite the flow of lava.

The southern end of the island is being pushed up from underneath, and has now risen 24 centimeters, even after three full days of lava flowing out from vents. Here is the official government sensor reading:

In answer to last question.

Etna exploded! The most powerful volcanic eruption in Italy!
https://youtu.be/JW5wUxKj964

Another big eruption is still ongoing in the Canary islands. Earthquakes have reached 4.2 on the Richter scale, and the ground is still rising on the mountain, showing that the magna is still building underneath. This eruption could go on for several more weeks. And, there still is a danger of the mountain sliding into the sea that might create a dangerous tsunami that would hit the east coast of America.

This seems to be the most scholarly modelling of a potential tsunami:

https://websites.pmc.ucsc.edu/~ward/..._Palma_grl.pdf

Looks like here in Gran Canaria we can expect between 100m and 150m waves about 40 minutes after it all kicks off!

UPDATED 3:15 PM EDT -- GETTING WORSE: LaPalma Volcano Update
UPDATE 3:15 PM EDT --

From the Government of Canary Islands: "The Canary Islands Seismic Network has been registering a strong increase in the amplitude of the volcanic tremor since the last 4 hours, which is an indicator of the intensity of the strombolian explosive activity in the active mouths (vents) at this time."

(Hal Turner Translation: It's STILL getting worse!)
MORE:

INVOLCAN, which is the official Volcano Monitoring System of the Canary Islands is showing that the pressure of lava flow out of the existing vents, it LITERALLY now "off the scale."



(Hal Turner Translation: Things are not only getting worse, they've gotten MUCH MUCH worse!)

La Red Sísmica Canaria está registrando desde las ultimas 4 horas un fuerte incremento en la amplitud del tremor volcánico que es una indicador de la intensidad de la actividad explosiva estromboliana en las bocas activas en este momento pic.twitter.com/hWzbPhEdFg
— INVOLCAN (@involcan) September 21, 2021



EVEN MORE:

According to radio traffic from the GUARDA CIVIL, "The north of the island, which is supposed to be dormant is waking up."

SONIC WAVES ARE BEING REPORTED IN NEARBY VILLAGES DUE TO THE INTENSITY OF THE ERUPTION - WINDOWS AND DOORS ARE SHAKING

So I'm not into fear , just staying educated, and here in avalon is the place for that. Looks like this is building up pressure faster than it can relieve it , so sideways direction for now until more fissures blow , but in the law of physics , pressure takes the path of least resistance. Should this get locked up sideways and no fissures appear then the original site of the blow off becomes the point of interest. I have no idea what the odds are on this , this is way above my pay grade. IF and thats a big IF should this thing blow that mountain side , I would suggest what hal turner has been , going to the store for essentials and fueling up your car, even if its in the middle of the night. That would be most drastic case scenario, for now just keep an eye on this situation.

[I am B]

Tonight's reports here (8:30am now) say that a new vent oppened and it got into a more explosive phase.

I'll try to edit with articles.

... indeed, see this post (<---) and this article: La Palma no puede generar megatsunamis...

As Hervé mentioned somewhere in the "El Hierro" thread, the Banda Ace tsunami had a strong linear component whereas the putative La Palma one would be punctual. That means that the initial energy imparted keeps getting more and more diluted/distributed/dispersed/diminished along an ever increasing circumference of the wave front like happens to the waves generated by a pebble thrown in the middle of a pond. In such a case, the Canary Islands and West Africa might suffer, but there would be little energy left once going across the Atlantic.

That's a worse case scenario since it considers the slide to be instantaneous; if the sliding takes over 1/2 hour, then there is no sudden energy imparted to the sea. The difference in splashing could be compared to the difference between high-diving from a diving board in a pool and slowly getting one's toes wet...
