El Hierro

[jand]

On the above map of the earthquakes from just yesterday again its interesting to see they seem to be following the line staight through the area of the old Volcano Tansganagosa.

[jand]

OT but looks like the Volcano in Greece is one to keep an eye on aswell have a look at the links the magma flow is incredible.

Wakey, wakey, Guys and Gals!

Here we go:

Well good morning to you ! This looks very interesting. Is Santorini going to the focus of our attentions now that El Hierro is sleeping ? The implications of this one waking up could be severe. I was checking out a couple of websites last night and whilst much of the EQ activity in the region seems to be tectonic, experts believe that magama is on the move at Santorini.....

There is a lot of significant seismic activity near Santorini indicative of magma on the move:

Back to El Hierro the sea has been steaming since 1300.

Update 30/01 – 13:40 UTC

Note 435 AVCAN - earthquake activity - VOLCANIC - island of HIERRO - 31 January 2012-11: 00 pm peninsula - earthquake and volcanic activity continues moderate, with more microsismicidad and earthquakes located to have slightest sign of tremor. Emphasize 3 earthquakes aligned according to the supposed eruptive zone, located more to the South to 7.3km. Continues the signal of volcanic tremor in the eruptive zone of la Restinga, and although it is declining but still alternating periods with the tremor low and quiet periods in which is unstable and is seen. After a quiet morning, the tremor is rising in the last few hours. Still leaving floating and smoky pyroclastic sea which at the moment the claim is more evident that the volcano is in eruption. Magnitude between 1.4 and 0.4. New earthquakes 13. Depth between 11.6 and 14.3km (and one 7.3km and three others something more profound 16(1), 16.6 and 17.1km). Yesterday 12. Yesterday 9. Today will be 9. In total van 12091 earthquakes located in El Hierro by IGN from 9: 00 pm of the day 19 July 2011 (Henry).

Morning jand. I havent been following this thread for a week or so ( well it seems that long ) so in one sentence please, whats the latest?

[jand]

Morning TripleH

Erruption still ongoing new swarm of earthquakes happening daily shallower depths some unusually near the vent lots of steaming SLS much larger stain and talk that the magma is trying to find a new way up.

http://212.170.244.196/

Have a look at whats happening right now on the above webcam link.

I uploaded 5 screenshots of a helicopter over Bob. What i did not catch were a few lavaballons really jumping out of the water while the hei was hovering nearby.

Anyone else has seen some fontains of water in the last 15 min? It looked like something cant say if gas or stone, breaks through the surface with enormous power, they were at least 20m high. No steam columns, only enormous splash of water.
 For me a totally new observation.

Translated from Spanish.

Greetings; a couple of weeks ago I mentioned that I saw fumaroles at the Summit of Teide from my house; I've now seen again them and also have the graphic proof. That there are images taken so does nothing.

Hello Maria Belen. The fumaroles of the Teide are active on a daily basis. When it is cold at the Summit, the condensation of the steam is clearer and more visible fumaroles. The Teide is monitored with exhaust measurement stations. Does not constitute any danger which appear these small departures from steam. I them I have seen and photographed many times. The pictures are beautiful. (Elena).

Harmonics picking up again ?

in terms of seismic energy accumulated in the month of January, from the jam and subsequent earthquake of 2.8, the 25 day there has been a major release of energy, but if there is continuously in the form of small earthquakes (Henry) http://www.avcan.org/sismica/graficas/G782.jpg?t=1328010661

Update 31/01 – 13:14 UTC
 - 3 new earthquakes since our latest update. The 06:04 earthquake was by far the shallowest in a long time. Not the expect a new eruption vent shortly, but also the epicenter is totally different from before, namely to the South East of La Restinga ! If new shallow earthquakes might occur again there, we could end with a new situation.
 31/01/2012    06:01     Depth 12 km        M 0.9     SW FRONTERA
31/01/2012    06:04     Depth 7 km        M 0.7     S EL PINAR
31/01/2012    06:09               M 0.5     SW EL PINAR
 - Harmonic tremor grew to a higher level after 06:00 and is still higher at the moment compared to early in the night. Additionally we have a lot of hydromagmatic bursts today. Again a new situation. This volcano continues to surprise us.
 - ER reader New has seen some ignited gas lava balloon flashes yesterday evening and early this morning (yesterday in between  21:30 and 21:45 UTC and today at approx. 07:25 UTC).

Thanks jand, so basically much the same as a month ago?

[Florence]

Basically, its what has been happening since last July.  Hence 9 pages of pretty much the same.

[jand]

Florence / TripleH

No its not the same as a month ago that was a very very brief summary and things are changing daily especially with whats happening on the stain at the moment.

For the first time today have been hydromagmatic bursts .

As whatever I reply will be slated I suggest in future you read through as everyone else is who is interested to see what has changed since July.

Todays video from the helicopter the colours are breathtaking and you can really see how large the stain has grown.

Magnificent.[] Love todays photos too. Thanks jand.[]

Have a look again at this photo on the post Posted - 27 January 2012 :  15:13:02  .

Then have a look at the photo posted today at 1855 you can see the vents and line of fissure they look identical to what Dr Elena marked.
