El Hierro, Canary's - Red-Alert, Eruption Underway

[Nightwatch]

teideano:

Evacuation under way in El Hierro, evacuation under way in El Hierro. Magma migration should be inland.

The light is red for RESTINGA AREA, WHILE THE REST OF THE ISLAND IS KEPT THE yellow light.

Quote from the Mayor El Pinar to which the neighborhood of a Restinga: "Scientists have confirmed to me that approximates a mass is large and therefore we have taken these steps"

According AVCAN Facebook page " IGN expects new earthquakes of greater intensity, the epicentre of the last few hours has
shifted to the interior of the island"

Red alert and evacuation in the south of The Iron before another possible eruption


http://traductor.elmundo.es/Pages/UrlTr ... nates=True


Already there has been completed the evacuation of 547 inhabitants of The Restinga

Only half a hundred of persons needs an emergency housing

It is believed that the eruption will be more superficial and with ' major explosivity '

The people(village) is the populated point nearest to the submarine eruption of yesterday


Maxim is alert in the south of The Iron. The inhabitants of The Restinga have been evacuated to Valverde and other points of the island more removed from the coast without any incident, after having be Raised up to red level the semaphore of volcanic alert In this locality for the possibility that there takes place(is produced) an eruption more superficial than that of yesterday.

The general manager of Security of the Government of Canaries, Juan Manuel Santana, has made clear that this measure takes with Preventive character, Before the seismic signs that indicate that it is probable that a new eruption takes place(is produced) In waters nearer to the coast and less deep That on the one that was registered yesterday, Monday.

" An eruption in more shallow waters might produce major risks, because it(he,she) would have major explosivity ", Santana has indicated. The rest of the island they are in yellow alert.

In a press conference offered in Valverde, the capital of the island, Santana has preferred not speaking about "evacuation", but of " Preventive movement ", Because the situation can change with the course(year) of the hours and still(yet) there is no certainty from which the neighbors of The Restinga have to happen(pass) the night out of his(her,your) houses.

RTVC just showed some of the dead fish from south of EL Hierro being brought ashore.

Looked like a tuna type species. Definitely badly "burned. Whether by heat or chemical action I could not guess.

There is an alignment of the Earth, Jupiter, Venus on the 15th of October 2011. The Full Moon is on the 12. It might give this a nudge if the force vector passes through earth. Apogee is on the 12th also.

Special report: Update on El Hierro volcano eruption

Posted on October 11, 2011 by Jón Frímann

http://www.jonfr.com/volcano/


It is bit unclear what is going on in El Hierro. But from what I can tell least two things have happened during the past 24 hours. The first thing is that a eruption started at ocean floor around 04:18 UTC yesterday (10 October, 2011). This eruption appears to have been small and was not noticed on the surface of the ocean. Around 06:10 UTC this morning (11 October, 2011) a large movement of magma started to take place inside El Hierro volcano. Where exact break up of this magma is going to take place is unclear at the moment. But it is clear that a eruption is taking place and it is more chance then less that magma is going to find it self a new pathway up to the surface soon. As I do not think that the current eruption vent is keeping up with the current magma that is under El Hierro. But it is worth to notice that El Hierro does not seem to have a magma chamber, like Eyjafjallajökull volcano in Iceland so the eruption size is terminated by the current inflow of magma.

Here is my personal assessment on where eruption might take place in El Hierro. Please note that it might be completely wrong. But I base my assessment on the data out there, that assessment might be wrong.



The most chance of the eruption in El Hierro in my personal opinion marked by the two red circles. Copyright of this picture belongs (original) to Instituto Geográfico Nacional.

There have been some deep earthquakes in El Hierro volcano over the past few hours. This deep earthquakes mean that new magma is flowing under El Hierro volcano. This means that the flow is steady (pressure pulse in the magma creates the earthquakes). So this eruption is far from being over it seems. How long it is going to last is a good question that currently nobody has a answer to at the moment.

Tremor amplitude takes a sudden drop

[expat2carib]

Does this mean the magma is settled down? Or does it mean eruption?

Million dollar question.

Maybe it has found a new route.

Seems the pressure is off the bottle...
might be a good thing? ...
or building for a new one?

Special Report: Update 2 on the eruption in El Hierro
Posted on October 12, 2011 by Jón Frímann

http://www.jonfr.com/volcano/?p=1628


The eruption in El Hierro volcano continues today, as it did yesterday. But the strength of the eruption appears to have dropped today from what it was yesterday. But this does not mean that the eruption is over. It just means that the current fissure that is erupting is about to close up, mostly due to the material that it has been ejecting into the ocean floor. That means a new fissure or vents is about to open up somewhere. When and where is impossible to know. But this is the nature of volcanoes that erupt in this manner, but El Hierro is a shield volcano [second link here]. Good examples are Krafla volcano and Vestmannaeyjar Island volcano. Both of those volcanoes are in Iceland.

Today around 14:20 UTC there was a sharp tremor drop in El Hierro. This means that the magma flow dropped in the current eruption fissure. This also means that if the pressure is not enough that fissure is going to stop erupting. Because of this has happened a new fissure or a vent should be expect at any time as I have told before. When and where that might happen is impossible to know, as that outcome depends on where the magma finds its pathways inside the volcano. There might not be any earthquakes before this happens, as the rock is unlikey to be hard enough to make them. Some small earthquakes might happen if the rock layer is hard enough. Today few deep earthquakes have been recorded. This means that new magma is getting into El Hierro volcano from the mantle (where no earthquakes happen). This also means that this eruption might take place for some time now. But it is impossible to know for how long, as there might be a lot of magma flowing up from the mantle it self and up to El Hierro volcano.

Many people have been wondering why this eruption has not been seen. The fact is that depth drops quiet fast around El Hierro Island. Around 4 km out the depth is close to 1.5 to 2 km, it is only close to the island that the depth starts to get shallower. At the moment is is hard to say what happens next in this eruption on El Hierro. But more vents should be expect to open up then have already have.

[GCANE]

Update 12/10 – 20:04 UTC : 2 new eruption locations have been detected this afternoon. The eruption sites discovered today are much nearer to the coast than the initial location at 5 km out of the La Restinga coast.

Today’s most remote location is at a depth of 750 meter and 2 nautical miles out of the coast. The second at a depth of 500 meter and 1.5 nautical miles from the coast. (1 nautical mile = 1.85 km)

Authorities told the press that fissures has been opened which resulted in green water spots with a strong sulfurous odor. Just like Monday a lot of dead fish have been detected at the surface waters too.

Scientist are hoping that the present submarine eruptions will decrease the pressure on the main island and are hopeful that the tremors will weaken.

The new fissures have been opened when we reported the strong change in seismicity during the afternoon.

Update 13/10 – 09:10 UTC : The green water spots are still there this morning.
- some of the scientists are currenly staying in La Restinga, the evacuated city/village.



The YouTube video below shows the green ocean areas to the south of Puerto Naos. IGN has categorized the green water as a clear indication of the eruption, although many observers are not sure at all that magma erupted. Some expert volcano followers are indicating that the green color might come from gas which is emitted out of the fissures, NOT from released lava. The dead fish may be additional proof of such a scenario as well as the change in harmonic tremors. As long as we will not have a visual image of the eruption, speculation will lead the debates

13/10/2011 @ 09:01 – A new earthquake has been detected, this time to the north-east of the island. Until now, all the earthquakes have been located to the south coast. It took place at 05:10:36 (local time) and registered 1.7 on the Richter scale.

[GCANE]

13/10/2011 @ 11:41 – Residents of El Hierro have been observing the formation of ‘green patches’ on the sea surface, some 1 and a half miles from land, which appear to be growing in size at a rapid pace since this morning.

Details from the stain can be observed sea from the coast of El Hierro.
