Tirelessly updating Avalon on the El Hierro eruption.

Frequencies spectrogram, the vertical streaks indicate “events” (tremors/EQs) whereas the horizontal ones reflect volcanic/magmatic activity:

From Wikipedia: A Harmonic tremor is a sustained release of seismic and/or infrasonic energy typically associated with the underground movement of magma and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

* : Polly was so named from the “polycephalic snake” look of the initial cumulative energy graph (see post # 327).
The name became most appropriate when the eruption from multiple mouths/vents/cones/heads started to develop.

Sorry old Bud,
Why is this at the top page news!

The only thing I can imagine, is that what may incoming, i.e. Solar flare. possible comet,astroid,or
hitting the Rift, or nuclear annilation. OR NATURAL earth changes!

[Amzer Zo]

To get an idea of what's happening currently with El Hierro, imagine that the Meridian Island is sitting on a giant water bed but, instead of water sloshing around, it's a more viscous (less fluid) magma that's moving around.

Hence, what one sees happening with the GPS is magma moving around from one corner of the bed to another.

Since said magma hasn't yet found (or punctured) a hole through the upper mantle (manto) and Moho boundary; well, then, the magma keeps sloshing around over a period of several days.

The following illustration given as an explanation for the previous eruption shows that the earthquakes located within a 25-17 Km layer have therefore not gone "over" that Moho boundary.

If/when that happens, then an eruption can be expected; not before, unless a major EQ blows gasket, cylinders head and engine hood all in one shot as happened the last time with a Mag 4.4 EQ on Oct. 8, 2011.

I suspect what you're asking, Ol' Roy, is why this thread is "sticky", which keeps it near the top of the active thread lists.

Amzer Zo ... perhaps you have thoughts on this ... whether this thread is still one of those few threads that warrant being sticky, so people are less likely to miss them. I will confess that I've not been following this thread closely of late. My (ill-informed) guess would be that it's not a key thread that should be sticky now, but that if something "heats up" again, it should be made sticky again.

Your thoughts ... ?

[Ol' Roy]

I respect all that is useen to the Amatuer ( beng me). Thanks Amer Zo for this clarification. Most of us dumb ass's don't understand with all your charts and grafts. But wih your recent explantain, I do understand what you are talking about.

Please forgive my ignorance on this subject. I have been following you since day1 . I do appreciate your post.

A little explanitation with each post would be be appreciated .

I do have a lot of interest, as well as many Avalon participrents, if you you kindly put it in layman terms.

We are tiredly awaiting your interuptations of these events.

Much thanks to you,

Ol,Roy

Your thoughts ... ?

My sole objection to "un-stick" this thread from under the "Climate and Environment" header is that compared to the other "sticky" threads under that same heading, El Hierro draws a steady 10,000 viewers monthly.

Accordingly, keeping the thread as a "sticky" makes it easier for these 10,000 viewers to find it and get the current updates...

That's my few cents....

You've got a good point there -- this is the hottest thread by far in "Climate and Environment".

I'll just leave things "stuck" the way they are.

Cool .

A big

THANK YOU !

to the more than 150,000 viewers who visited this thread!

Since July, IGN has officially logged 15,147 tremors at El Hierro... and still counting since the seismic activity is still on going!

Thank you for your support and for dropping by!

THANK YOU !

Sneaky Polly... she grew up 4 meters while no one was watching!

Following the trail of a comment on Earthquake-report.com (http://elhierro1.blogspot.be/), it appears that the main underwater cone, instead of being dismantled and crumbled down, grew up by 4 meters from a depth of 88 m up to 84 meters.

That simply means that magma kept erupting -- very -- quietly under everyone's nose.

This is the bathymetry as of June 9, 2012:

... and the one from Aug. 27, 2012:

The increase in elevation is not very obvious from these pictures but that's what the commenter was told by the Atlantic Explorer's crew and which needs to be further verified at the ULPGC for accuracy.
