First of all my sincere congratulations to Julio del Castillo Vivero who is updating this article when i am traveling (with a 7 hour time difference !). Julio is not only a great time lapser (see the video with his flashing lava balloons today) and photographer, but has been following the El Hierro events since a couple of months now + of course Joke, thanks to her activities, all the readers of this article are almost present on El Hierro – Armand

THE SUBMARINE VOLCANO IN THE RESTINGA CONTINUES EXPELLING MAGMATIC MATERIAL TO THE SURFACE.


01-02-2012... 12: 32 - Ministry of economy, finance and security


In yesterday could appreciate different hues in the stain generated by the eruption


The submarine volcano of La Restinga has continued expelling magmatic material to the surface of the calm sea intermittently during the past few days.


Since early yesterday, as it confirms the National Geographic Institute, you could see in the area of emission the presence of ash generated by a central Brown and rings of different colors around it, surrounded by a large area of green in the English channel. As the day progressed, the area of emission of ash decreased from size and greenish area was extended in this direction. Throughout the day was observed gas emission and fragments of steaming lava, on the morning of continuously and by the evening of intermittently.


As regards seismicity, IGN found yesterday 13 earthquakes of magnitudes between 0.7 and 1.7 and depths between 12 and 17 kilometres to the West of the island, in the area of El Golfo and El Julan. Monday, January 30, there were 14 movements with magnitudes between 0.4 and 1.6 on the Richter scale, in the same area and at the same depth.

EARTHQUAKES 31ST JAN. -Green course (3)
EARTHQUAKES 31ST JAN. -Red (14)
EARTHQUAKES 30TH JAN. -Blue clear (13)
EARTHQUAKES 29TH JAN. -Pink (16)


Earthquakes today are three, the last in the mar de las Calmas, and the other two in the Gulf area, one on land and one at sea. Senotan NNW-SSE alignments by dorsal South area and in the normal alignment. Last night focused activity in the area of summits and under Tanganasoga, in addition to some in the calm sea and border, three of them close to the area eruptive aligned NW-SE, to all these we must add several antesdeayer in the same area, but more widely by the central part of the island, and one in the Gulf Coast, three in the area of summits and two in the mar de las Calmas near the Julan. The earthquakes of the day 29 are more westward aligned in the direction of NNW-SSE from Sabinosa until the mar de las Calmas passing through the area of summits.

Eruptive surge in la Restinga. No, it is not now effusions of balls. It's a surf spot, produced by the volcano, which must have earned meters in height and is approaching the surface lentísimamente. (JR)

I can assure them that the phenomenon described as storm surge is real, we have seen that in the days of increased activity and lately is very common and it is real waves emerging from the center of the warhead on the submarine volcano sideways. What should happen now, is that to register output of steaming balls at the moment and match a strong wind to flush with water of more than 25 knots, shape in the ridges eddies white with foam, we see just in that area. We have seen waves of nearly two meters in some moments, what happens is that the images of the webcams are taken from positions with little azimuth and are almost flat and very distant. I think JR is very successful in his commentary.

I should imagine that there are a lot of people who read this thread and don't post, just keep up to date with the info and click the links that interest them.
I fail to see anything constructive in anyone taking the trouble to post disparaging comments; in fact it says a lot about the posters methinks...on one hand there's folk willing to share information and opinions and pull links together in one place...on the other there's folk who like to think they are clever with 'playground' remarks - Enough chips on shoulders and sour grapes to feed a vegetarian army! I cannot see ANY reason for it.

Let Jand do her excellent updates without them being sullied by nitpicking and childish jibes - if you have nothing constructive to add to the thread, go do something more positive than dissing a fellow Canaries lover instead.

Florence you hit the nail on the head your quote shows ONE earthquake near Ireland  maybe you have not grasped the difference in what happened in Ireland and whats happening now in El Hierro shall I enlighten you.

The difference is El Hierro had 46 earthquakes alone in the three days before the 2.1  happened!!!!!

Update 02/02 – 06:45 UTC
 - 2 earthquakes since our latest update
 02/02/2012    04:40     13        0.9    W FRONTERA
 02/02/2012    04:41     15        1.1    W FRONTERA
 - harmonic tremor all night the same, not very strong but neither at minimum

Update 02/02 – 02:21 UTC
 - At the time of this update IGN has listed 1 earthquake since midnight :
 02/02/2012    00:36     Depth 12 km        M 1.1     W FRONTERA
 - Harmonic Tremor is still strong enough to speak from a sustained magma flow. We might have to watch the waves as described by Julio and Joke. If they are increasing the following days with a limited HT (like now) we might go into a new phase as the vent gets closer to the surface. The lava balloons are not specifically linked to a lesser depth of the vent. The same process can occur at depths of several hundred meter.

Yes, the wind is coming from the south east, but there is a vent 100 metres outside of the righthand wave-breaker. And remember that it is gas being vented here, and if that gas goes into La Restinga people will get mighty green mighty fast...

Have they evacuated La Restinga?
 There is a vent right outside the harbour mouth, and if the progression continues the next will open inside the harbour.
 This is bad, I hope the IGN is ontop of it. If a vent open up in the harbour people will become gas poisoned quickly if the wind is not very strong.

The 0,59 and the 0,26Hz tremor is back very clearly today on both EGOM and EOSO. Looks like new magma being pushed up again. Bad news for La Restinga.
 Is there anyone who can check if they have prepared for, or have started to evacuate La Restinga?

Hello Leoonardo, the increase in la mancha there is no doubt that is by biggest outflow of material, but is also due to a change in through departure, where there is more interaction with the water, causing the material is fracture and chop more by explosions. When they go out balls of lava piroclasticos afloat there is less interaction into the output pipe, now do not go, but the color is more dark, indicating a greater trituramiento of material that comes out.
Avcan FB Copied and Translated.

These past days has been deep seismicity indicating contribution of magma at depth, there have been several Lps or Largo-Periodo events that indicate movement of magma by depressurization to certain discusses the measurement of gases, specifically CO2 by the INVOLCAN reflects an increase, the deformation in the Restinga according to the GPS of Nagoya reveal a small inflation (to the IGN nobody has access) and the tremor has not stopped... conclusion the eruption increases its activity with respect to past days, far from stopping, has another increase in its activity (Henry).

Continues the signal of volcanic tremor in the eruptive zone of la Restinga, which is increasing its activity, because since the reboot at 07: 00 pm yesterday, has not stopped, as came doing the previous days, the explosive has dropped something, they are less hidromagmaticas explosions. La Mancha produced by the output of materials under water is larger and is morning has gotten into the port of la Restinga. Magnitude between 1.6 and 0.9. New earthquakes 5. Depths to 10.1, 12.2, 12.5, 13.1 and 14.8km. The day before yesterday 14. Yesterday 5. Today van 3. In total van 12121 earthquakes located in El Hierro by IGN from 9: 00 a.m. of the day 19 July 2011 (Henry).

Well... well... welll.

Dear people of IGN...

You ara a SHAME...

Where are your reports (february 1st) for january 31th?
 Where IS the month of February in your page?

I´ll answer...
 The report of February 1st, for january 31th is made under and in the name of PEVOLCA, not as a comunication of IGN.
 I assume you finished reports in your page and PEVOLCA will be the Lord of the words...

You´ll never learn...
 Shame shame shame...

Dear Diana and Geoloco I assume a volcano can be predicted more than you think, but in this case these litle sheeps are making reports under a political flag or administrative flag...
 These litle sheeps know more things than you can expect... hahhahahahaha

 Always fun to read you.
 There's a difference between "predicting" that an active volcano like Bob might grow in activity and even have some potential onland than predicting anything about Campi Flegrei. Each swarm under such a beast can be the "usual nothing" as the start of whatever. And even if you predict that now starts an trip towards a big bang, who will listen to the good Randy and begin the "depopulation" of millions of people declaring "according to geologists it might be that from now until in 50 or 100 years this whole area will look like megamegameganuked, so in the 10 years to come you will all have to find a job and home and football club somewhere else at least xxx km far away". I was once in the situation to be one of 3 scientists recommending the decision makers to evacuate something like 40 people for something like 3 or 4 days. And there was not a lot to predict, it was in a valley and we were standing in the middle of the whole poo around us coming down... Yeah, well, you know, I let you go with the try to evacuate Napoli on the basis of some earthquake swarms under Campi Flegrei...
But the sheep you're talking about sure know a lot they are not to say...

Thats a pretty handy sequence.

you can even make out how some of the pre-existing sediment has been disturbed and flowed down the northern side of the slope and how it lays against other features/rises.

My point is that there is no need to get worked up about the small earthquakes.  It means that there is a movement in magma with some coming to the surface off Restinga.

I am interested in this subject but this forum is not the place to find out anything meaningful because all we can see are a multitude of postings that do not make sense in any language.  That is a constructive comment.

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.

I see what you mean jand. The fault line seems to be getting weaker and weaker. It looks like it will soon be in the Harbour.

What does it mean tremor and seismicity were given at the same time?
 This means that energy is flowing out (tremor) while inside there is more energy (seismicity), prepared to continue flowing out.

Update 03/02 – 02:34 UTC
 - A M 2.7 earthquake with a depth of 12.6 km at 01:14 UTC has been felt by many people on El Hierro island, including Frontera and La Restinga. The earthquake occurred at a location with high daily seismic activity for the past weeks. Epicenter: 27.7002 -18.0593  W EL PINAR

Well, I think that magma is cumulative in that area, before earthquakes indicated us the passage of the magma of the North (where it is usually give the entrance of magma to the great camera or whatever) towards the South, towards the volcano; but little by little could be seen both the behavior of the tremor, and seismicity that magma had problems on that journey. Meaning that channels through which passes are clogged, even were these significant stoppages of play activity. So I think that although the volcano is still much, expelling the steady stream of magma and problems in those ducts makes for a zone under the Julan, Tanganasoga, Pinar, throughout this area more or less, where magma is cumulative. That is why these earthquakes have occurred, and they remain in place.
