Here is a good map of El Hierro...well labelled:

Strong seismic activity at different depths

About to blow?

Magma maybe on the move again this is the station near El Julan CJUL.

I don't know what those graphs show..seismic? but, eeks!

This looks like a big one ??

[link to www.02.ign.es]

No!

What makes you think that ?

It's been fairly quiet lately until today and now stirring with lots more quakes including shallow.
My question was only half serious after I noticed the seismic graphs ramping up from flat-line.

I'm not sure if you noticed but I will point out that this thread was started August 2011 when the activity started... and subsided.
We have had this year another significant swarm ... that subsided also.
This activity is so very minimal at the moment to what we have seen in the past year that it CAN be sniffed at.


The charts are NOT showing harmonic tremors, which means there is NO volcanic activity.

Why do you think it is going to blow ?

what is this CJUL chart?

[link to www.02.ign.es]

where on el hierro is it located? it's a new one on me.

What are you on about the charts are showing new Harmonic Tremor as shown in the graph below .

CJUL is the station in the EL Juan area of El Hierro.

i agree it is showing harmonics, but that image isn't working.

omg?

really?

el julan?

that's where the big cliff is precariously perched!

[link to picasion.com]

so, the strongest signals right now, are right under a multi million ton slab of rock, perched above very deep water?

A rise in Harmonic Tremor can also be seen on this graph.

[link to www.02.ign.es]

this is weird. these signals at el julan have NO underlying volcanic tremor, down in the 0-1 hertz range, so WHAT is causing these tremors?

I didn't realize there was NO volcanic activity associated with El Hierro, the Canaries and the graphs. Maybe a whale fart in the ocean. Please ignore my post and thanks for your info.

Interesting to note that the NO volcanic activity from El Hiero is mirrored on Gomera since 18:00 but to a lesser degree.

Seems there are two major chambers, upper & lower, that have been active today. [link to www.ign.es] It would not surprise me if there was a volcano brewing down there but that's just a guess. Ha

watch the el julan cliffs!

Were BACK in Business......


The volcanic island of El Hierro is really turning into the Little Volcano that Could.

3 earthquakes seem to have changed the ballgame around once more. First came two deep earthquakes at a new spot at 10.10 in the morning, both of them at the depth of 20 km. 26 minutes later followed a 2.6M at 10 kilometers depth.

Within minutes a sharp increase was noticed in the high frequency tremor. The tremor lacks low frequency components making this a dead giveaway that we are seeing a de-gassing event. What has happened is that a persistent earthquake swarm north of Balneario Pozo La Salud most likely finally cracked through and things started to move up beyond the de-gassing threshold.

After the 10.36 earthquake the shallower earthquakes pretty much disappeared and we had an onset of a new active deep earthquake swarm. In retrospect it is clear that we most likely caught the arrival of a new bolus of magma arriving from depth. If so it is the fourth time new magma arrives from the depth.
