Volcano Watch 2012 !

OK...looks like El Hierro is giving cause for concern

Especially givn the type of volcano it is

and the guarantee of €600,000 (~$750,000) from the government to aid fishermen whose livelihoods had been altered by the closed fisheries.

they pay up yet??

Just had a look at the seismo at El Hierro and it seems activity since 24-06-2012 at around 21:30
No eruption at the moment but whatever is going down there could lead to a new one.

Keeping an eye on that one.

"El Hierro’s volcanic alert status raised to ‘yellow’ following increase in quake activity
Posted on June 27, 2012 by The Extinction Protocol
June 27, 2012 – CANARY ISLANDS – Seismic activity has increased on the volcanic island of El Hierro. The INVOLCAN, the Volcanological Institute of the Canaries, and the PEVOLCA (the Civil Protection Plan for Volcanic Risk), have raised the alert status in parts of El Hierro to “Yellow.” About 580 earthquakes were registered from Monday to Wednesday. Thirty of them were greater than magnitude 3 on the Richter scale – a level at which they can usually be felt. The volcano 24 hour monitoring network, National Geographic Institute (IGC), recorded a total of 221 earthquakes on the island of El Hierro, specifically in the municipalities of Frontera and El Pinar, on Tuesday June 26. –The Extinction Protocol"

Ummm....very disturbing news on that site with the latest report:

Today ER report Update 28/06 – 13:25 – New PEVOLCA press report (translated by ER) We have observed a deformation of the entire island. The center of the deformation originates in the present earthquakes area (see below) The energy release and ground deformation show an acceleration of the active magmatic process on the island of El Hierro, according to information forwarded by the National Geographic Institute at the direction of the Civil Protection Plan for Volcanic risk (PEVOLCA)

The GPS network solution, measuring the surface strain on the island shows that there is a clear process of inflation, marking an apparent center of pressure in the area where the seismicity is located. The total cumulative displacement from 24 June to 24 hours yesterday, is about 3-4 cm in the horizontal components and 4-5 cm in the vertical component. Since the beginning of the new magmatic process on June 24, there have been over 750 earthquakes. An earthquake with a Magnitude 4.0, occurred yesterday at 18:55 pm in the Las Calmas Sea, 2 km from the coast and 20 km deep.

Be remembered as the seismicity started in the El Golfo bay, then moved to the center of the island, coinciding with the point of intersection of the ridges, and later migrated to the west. Since the 25th of June the seismicity is concentrated in the west and El Julan. From 12:00 hours. On 27th of June, seismicity began to migrate towards the Las Calmas sea. Comment ER : Our regular readers will find 1 surprise in this press report (the rest has been treated in many updates) – the even stronger than expected vertical deformation of the island emphasizing the very strong energy below the island (4 to 5 cm).

Strange thing about it is I was just at my parents house picking up my daughter and randomly she said she had a bad dream about a Volcano in Florida last night. She is only 5 so I couldn't really read much into it, but she said she was on the way to Florida in the car and saw a volcano explode. Of course it is most likely attributed to something she is learning in school or saw on a cartoon, but still....kinda disturbing to me.

i posted this link on Quakewatch but i think it really belongs here.. lots of updated information.

Wow,.
kinda exciting in a scary way,.
watchin this one for a while,. thanks

check this one out...

The guys on there know what they are talking about

They are apparently messing with the seismo readings over at El Hierro.....which is VERY disconcerting!

Very interesting. Anyone one have any input or info on if this is abnormal? Didn't see that one until your link.

Video from it erupting a year ago. Neat to see something like this but wonder what it could actually do.

This just posted within the last half hour by Jon Friman over on Erik Klemmetis website

"Jón Frímann Jónsson 1 comment collapsed Collapse Expand
It is just matter of hours to days at the longest before a fissure type of eruption starts in El Hierro volcano. Magma is now clearly forming a path to the surface. How long that is going to take depends on the crust. Something that is hard to impossible to predict. "

At last, a year later, NABRO is taking its place amongst climate changing volcanoes.

For most NABRO was just maybe a little volcano in the passing by;
yet in reality it did affect most people in the Norhtern Hemisphere - and still does to this day.

All the info on El Hierro you could need

www.01.ign.es...

There has been a sudden rush of earthquakes today. 50+ so far of which 19 are 2.5+ between the hours of 09:30 UTC and 12:00 UTC.

Mm, just looked at the GPS. Take a look at 05 and 10




Now look at those on the map


That is a big area of lift - 15km or so between those 2 high points.

Jon Frimann is talking about fissure eruptions as is Klemetti, but..........

ETA: Here is a (very small) map of the uplift. See my blog for the full size version (signature)

But whats happening on Santorini?

Santorini has been active for a long time now, but suddenly, its activity has decreased dramatically. There hasn't been earthquake for a month there. This would mean many things, but tremor actually decreases when lava finds its way to chamber. Same thing happened at El Hierro last year, tremor almost stopped, then it erupted.

I say its quiet before the storm. Santorini could go off at any moment, eruption is not likely very strong, but still. Volcano mostly blowed up during Minoan eruption, and cannot do similar eruption now.

Thank you Puters!

can it be verified that Katla /el Hierro and Santorini have the same triplet sequense of swarms and activity?
at least katla and hierro eased down in the same time...

Just out of interest, have any of our UK members being watching Volcano Live this week on BBC2? Link for those interested......Volcano Live

Fairly simplistic at times i have to admit but there have been some very interesting bits in there too. I am always slightly in awe of Vulcanologists anyway but last night they had a video report from a geologist from last years Mount Puyehue eruption in Chile - camping near the summit during the eruptive phase!

Like i say basic at times but certainly very interesting.

Here is another fantastic blog about El Hierro just packed with information and well followed with many good comments.

This page may be of interest: El Hierro and the Physics of magma chambers

@ Flavian....yes I have been watching although I have had to record tonight (Wednesdays) broadcast and as yet haven't had a chance to watch it...no spoilers please!
I agree with your assesment of the programme...but still interesting non the less. Believe its the old 'supers' on thursday night.

@ Puters...diolch yn fawr eto! I will have a read tomorrow as no doubt it will be precipitating and I shan't be able to get into my garden!

Well i have tried the search function so apologies if that proves to be a wasted link..........

Here is a link to The Smithsonian volcanic activity update pages.....

Smithsonian Volcanoes

Various info about many volcanoes as well as weekly and monthly updates on activity. Enjoy
