Detected an earthquake of 3.8 degrees northwest of La Frontera
Emission points of the line underwater eruption in the Sea of Calm
Risk if the earthquakes exceed 4.5 degrees
Remarkably sharp decrease of seismic activity
Weapons Alpidio "areas like La Restinga die"
There is no life at 1.5 miles from the eruptive source
The Canary Islands government has reported the alignment of the emission points of the submarine eruption along the fracture in the Sea of the calms of El Hierro, noting the pictures taken by the scientists of the National Geographic Institute (IGN) in a flyby of Emergency and Rescue Groups Canary Islands Government (GES).

The regional administration indicates that the images can be seen smoking pyroclastic materials and bubbling caused by released gases.http://www.universocanario.com/siete-islas/el-hierro/erupcion-volcanica-en-el-hierro/emergencia-el-hierro/focos-de-emision-erupcion-se-alinean-mar-de-las-ca/281497?utm_source=twitterfeed&utm_medium=twitter

Wow - amazing photos fifi.

If you had the misfortune of being in a boat and hit by that turbulance, you would sink like a stone to the seabed, due to sudden lack of buyancy.

There are reports on Avcan this was also felt in the North of Tenerife.

Don;t know, people at AVCAn are also wondering about that.
 But someone said the earthquake was felt in the North of Tenerife, at Los Realejos, about 90km away.

Has anyone else on Fuerte felt anything.

Below just posted on Avcan by a Spanish person.

Don't want to be alarmist, but a few seconds before reading it in the post, I felt two tapping as stop of lift in Fuerteventura. Very soft, but dry.

AN EARTHQUAKE OF MAGNITUDE 4.4, WITH EPICENTER IN FRONTERA, HAS BEEN SENSE IN LA GOMERA AND TENERIFE...


04-11-2011... 21: 18 — Ministry of economy, finance and security


It has also been felt in Arafo and Santiago del Teide (Tenerife) and Valle Gran Rey (La Gomera)


IGN has confirmed to the direction of the PEVOLCA that there has been an earthquake of magnitude 4.4, West of border, with a depth of 21 kilometres.


This earthquake has occurred in an area close to the coast of the Hierro municipality and has been felt, in addition to the three municipalities of El Hierro, Arafo and Santiago del Teide (Tenerife) and Valle Gran Rey (La Gomera), according to calls received in CECOES 1-1-2.


This movement has caused some landslides in the core of Sabinosa, and on the slopes in the area of Guinea.

The last earthquake showing on the Islands tremor charts

[jand]

Without being shot down I am trying to ask a sensible question.

The Japanese Tsunami was caused by eartquakes causing rifts under the sea is there not a possibility now that these earthquakes happening in the Canary Islands undder the Atlantic ocean could do the same ?

[fifi]

It is possible jand but not predicted at the moment. It depends on what happens.

Article posted previously....

Mega Tsunami theory never proven, local Tsunamis on the Islands with waves of 50 metres proven. La Vangardia (Translated)

"It's pure speculation in the past a tsunami originating in the Canary Islands came to the U.S."
Luis Ignacio Gonzalez de Vallejo, Professor of Geological Engineering from the Universidad Complutense de Madrid said however, that in the Canary Islands there have been waves of up to 50 meters created by large landslides

[jand]

Well all I can say is why the hell have not the Canarian Goverment placed Tsunami alerts on all the Canary islands.

This is not a dream or idle chitchat these earthquakes are happening right now magma is on the move and who can say its not happening under all the islands !!!

[fifi]

They have no reason to at the moment. Nothing has happened yet which suggests that it is about to happen. There is advance warning given for any changes in waves like there was yesterday.

[jand]

Fifi

If it was not for you yesterday lots of people including myself would have known nothing about the alert for highwaves.

How are people going to find out about a Tsunami alert if they have no mobile or internet connection or TV.

The happenings on El Hierro are not happening as expected Mother Nature is in charge now .

Surely now something like an air raid siren could be placed on each island (better to be safe than sorry).

[fifi]

Fair point jand. I think its safe enough though unless the seabed collapses or there is another landslide.

The EMU is ready for any contingency in the Hierrop
04.11.2011 / 19:10 h

Valverde (El Hierro), November 4 (EFE) .- The Emergency Military Unit (UME) is prepared for any contingency that may arise in El Hierro island where troops have moved 34 ready for any circumstance, said today Efe Santiago Diaz, press officer of that unit.

Santiago Diaz, lieutenant, said that the contingent of EMU is in El Hierro to perform all the necessary logistics for the organization of means that are necessary to successfully tackle any type of contingency.

The military barracks Anatolian sources in the village of La Caleta, municipality of Valverde, is these days the logistics center of the Emergency Military Unit.

In this quarter are deployed tents that house the equipment necessary to install a camp that could accommodate 2,500 people in the event of an evacuation, said Santiago Diaz, who commented that in the coming days will come more material.

Santiago Diaz said the material is moved to the island after the request by the Pevolca as a measure of precaution, and explained that at no time this should be cause for alarm for the population.

In this sense, the lieutenant of the Emergency Military Unit (UME) reported that in the case of EMU might be necessary to move in just 6 hours some 3,000 of the unit, which would be one hundred percent operating with resources that are already on the island.

In the same vein, Alpidio Armas, president of the Cabildo de El Hierro, has ruled out an imminent evacuation La Restinga and other towns on the island. EFE http://www.abc.es/agencias/noticia.asp?noticia=988056 (Translated)

11/04/2011 ... 23:57 - Ministry of Economy, Finance and Security


The direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) has decided this evening to close the access road tunnels Roquille until 7.30 am as a preventive measure before the earthquake of 4.4. which took place at 20:36 hours, Border, and the possibility that it could raise that amount, according to warnings from the National Geographic Institute (IGN). The opening of the tunnel in the morning will be done with surveillance and security measures.

It has also carried out the eviction of the 11 houses of the points that were more likely to be affected by landslides.

These preventive measures are discussed in separate morning meetings of the scientific committee and steering committee to assess maintenance or making other decisions that may be necessary depending on the situation.

Earthquake
The Emergency Coordination Center and Security (CECOES) 1-1-2, under the Ministry of Economy, Finance and Security of the Canary Islands, received between 20:37 and 21:28 tonight, 45 calls by inhabitants of the three municipalities of El Hierro and related to the earthquake that occurred this evening on the coast of the island

Also in that same time slot, the Canary attended 1-1-2 calls from some municipalities Arafo and Santiago del Teide, both located in the south of Tenerife, and Valle Gran Rey in La Gomera.

The most important incidents connected with this phenomenon have been associated with some detachments located in the heart of Sabina and in the area of Guinea, without consequences.

In this sense, IGN has confirmed to the direction of PEVOLCA that there was an earthquake of magnitude 4.4, the western border, with a depth of 21 kilometers.

Recent comment posted on Avcan by a Spanish person Translated.

When the pevolca says q is no risk to the population is a regrettable statement knowing the geography of the island the risk of retinal detachment by earthquakes of magnitudes exceeding 4 q already are, and a volcanic crisis q follows a course difficult to predict... I understand q want to calm but it is not question to say all the time messages from school playground... are talking about people within a fully active volcanic system and risk while it lasts and stays...

The Japanese Tsunami was caused by eartquakes causing rifts under the sea is there not a possibility now that these earthquakes happening in the Canary Islands undder the Atlantic ocean could do the same ?

The Japan tsunami was caused by a sudden upthrust of the sea bed where one tectonic plate slides under another. It was estimated that about 500km of the fault line was affected. That is on hell of a lot of water displaced & looking to go somewhere.
The earthquakes under & around El Hierro are cased by magma movements, not direct tectonic plate shift, & are a fraction of the magnitude

The only way you are going to get a tsunami from this event is if a large chunk of real estate falls into the sea (in one piece) or the seamount that is building under the water, falls apart.

What would you have the authorities do Jand? Close up shop in the Canaries, until this goes away? Even after this eruption stops, the risk is still there, however it is so small that one really should put more effort into worrying about more realisic threats such as driving, swimming & some of the more hazardous cliff climbs down to the beach.

I will be on the beach in a couple of weeks & have no worries about it. However I am not stupid, I know my nearest route off, & will take it should I become concerned about the sea state. Other than that, I am quite happy.

[fifi]

3.5 closely followed by 3.9 Intensity not calculated yet. From looking at the tremor on some of the other Islands I would say that they might have been felt again on some of the other Islands like they were last night.

This is a simple explanation of how the waves are created.

What is a tsunami?


A tsunami is an ocean wave produced by a sub-marine earthquake, landslide, or volcanic eruption.  It happens when a fault occurs creating a speed reduction with overlapping primary waves.  A tsunami poses danger to all land near the area of the disaster.  Just like earth quakes, not all tsunamis are large enough to cause harm, or even be felt.

Sorry Jand, but I have to play the Devil's advocate here. Its OK saying "Issue a tsunami alert" but then what? What practical measures would you put in place to keep people & property safe if you where in the hot seat Jand?

[jand]

Magoo

I really am trying to be practical here and do not wish to scaremonger at all.

I am not saying that the canarian goverment should start an island panic what I am saying surely under the circumstances at least they should put some form of alert maybe sirens on each island to warn people IF the earthquake tremors start a wave that could turn into a Tsunmi.

We had a 2.4 earthquake under the ocean on the west coast of Fuerteventura the other day.

Lets say you were on the beach on near the coast and did not have a mobile or laptop with you how would you know a Tsunami was on its way.

I am not talking about a huge wave this could be only three feet high but remember the force behind this would be the problem .

This subject is being talked about all over the internet and all over the world.

All I know Magoo is that no one can say 100% there is  not going to be a Tsunami wave whether small or large caused by whats happening around El Hierro at the moment.
