This is the video which they released about the area in the North. Its not great quality.http://www.youtube.com/watch?v=h5AW3lbFO5M It is supposed to be showing the new stain on the water in the Frontera (El Golfo area)



The Pevolca confirms a change in the seismicity being valued in terms of a new eruption

  The Steering Committee of Civil Protection Plan for Volcanic Risk (Pevolca) met this morning in El Hierro has confirmed a seismic shift in the north of the island that is being evaluated to "determine whether or not there is a possibility of an eruption at that zone ".
 

In this sense, the working group of the Scientific Committee met this morning, and attended by representatives of non-tip, IGN, CSIC and IEO, have referred to "a seismicity occurs at 20-26 km depth, associated with a possible feedback mechanism magmatic eruption process in progress. "

Also establish another scenario "at 10-15 km, which itself could be valued as a precursor to an eruption." Anyway it is still early to forecast, since the acceleration of seismicity at that depth, shallower, it is not producing an increase in deformation. The deformation would have to provide evidence in the coming days designed to ensure that there would be a new source of emission in the north.

For his part, hoped that the results of the analysis of helium, performed by the non-tip, to give more information. Recall that a month before the eruption of La Restinga there was a significant increase in the gas.

THE RESTINGA

The eruption process of the South, continues to develop normally, as indicated by the tremor signal recorded, and data collected by the ship Ramon Margalef, IEO, who believe they have seen a collapse of the volcano, with the data obtained with the echo sounder. Given the murky water, it is unlikely that the ship can take video images of the underwater eruption.

Current Volcanic Islands (AVCAN)
NOTE AVCAN 295 - EARTHQUAKE ACTIVITY-VOLCANIC - IRON ISLAND - 01 November 2011-11:30 h peninsular - Seismic activity remains high, with notable increase in seismicity in the Gulf region in terms of number of earthquakes and their magnitude, with a significant tremor signal, which has begun to increase significantly (by 50% in the last 6 hours). The magnitude of the earthquakes between 3.4 and 1.5. New earthquakes 55. Earthquakes senses 2. Depths between 16 and 24km (and one and 27km). The day before yesterday 92. Yesterday 156. Now go 32. A total of 10,864 earthquakes are located in El Hierro by IGN from 9:00 am of July 19, 2011

Also, from the Directorate General of public health have been made the necessary steps with the Sub-Department of fishing of the Canarian Government for the purposes of request to the Ministry of the environment, Rural and marine (MARM), the determination of dioxins and PCBs in the laboratory of the CSIC in Catalonia, with which the Ministry has an encomienda for the determination of these contaminants in fishery productswhose limits are covered by the aforementioned regulation.

Result of the autopsy as it can be seen from the autopsy of dead featured fish on the occasion of the volcanic eruption on the island of El Hierro, the most obvious injuries were found were the macroscopic characterized by gastric eversion, gas bubbles in the cornea, ocular haemorrhages, exophthalmos, congestion in organs such as swim bladder, liver, and gills, all of them as a resultboth of the explosion itself and by changes in ambient pressure at sea.

For this reason and although, in principle, the causes of the death of the fish not must cause illnesses in people, continues to recommend that the General Directorate of public health of the Health Department of the Government in Canary, as a precautionary measure, do not eat fish caught in areas affected by the volcanic eruption to not count the results of the investigation of polluting substances which is currently being made in exemplary captured alive in the area.

The Islanders continue to put pressure on the IGN over the missing information from station H104 which is necessary for the compilation of correct local deformation data. There is a growing mistrust amongst the population about the  information which is being made publicly available and  suggestions of evidence being tampered with are being made. http://es-es.facebook.com/pages/Instituto-Geogr%C3%A1fico-Nacional-de-Espa%C3%B1a-CNIG/156297191073688?sk=wall

IGN reply to the Islanders who kept asking what was happening to station H104.... (translated from above IGN link)

National Geographic Institute of Spain - CNIG
HI04 The receiver had feeding problems due to failure in their batteries. Currently, this process of repair. There are 7 more receivers on the island who are recording and transmitting real-time information to the scientific committee that analyzes the data. The HI03 is very close to the damaged receptor in which data can be retrieved. We hope shortly to restore the information to the HI04.
(Yesterday at 10:31 on IGNs Facebook page.)

There were many replies from Islanders some of which can be seen here.

"·in any civilized country in the midst of seismic crisis,  it's volcanic crisis, not even 24 hours later changed batteries and more specifically the HI04 which is key at this time."

" This response contradicts what IGN said to  Maria Jose Blanco, which was that the HI04 did not work for problems with wifi, and was already arranged on 27 October.
        Now, you say it's batteries, and is still broken. Understand that the public is confused, when from the same institution we are given contradictory answers."

The Ministry of defence plans to send between tonight and tomorrow the emergency military unit to the iron reinforcements. The idea is to be on the island ready for setting up the camp for up to 2,000 people if an eruption in the North of the island, is reproduced as it foreshadows the surge of seismic activity recorded since Sunday, when there have been several earthquakes of magnitude 3,9.http://www.elpais.com/articulo/sociedad/Defensa/envia/refuerzos/Hierro/posible/erupcion/elpepusoc/20111101elpepusoc_6/Tes.

The National Geographic Institute  supports the possibility of an eruption north of the island, opposite the town of Frontera, the most populous, with about 4,000 inhabitants. So far, the underwater eruption in the south just hit the village of La Restinga, 600 inhabitants. El Pais (Translated)

No problem jand.[:)]

The Roquille tunnel (which was recently reopened) presents a high risk of landslides. That is the main conclusion of the technician and Mining Geographic Institute of Spain (IGME)

The document stresses that the only risk is really high seismicity with earthquakes above 4.5 degrees. The rock falls occur regularly throughout the year, so these technicians have come to the conclusion that it is a tunnel which is highly dangerous.http://www.diariodeavisos.com/2011/11/01/actualidad/un-informe-revela-que-el-tunel-de-los-roquillos-es-siempre-peligroso

Islanders are still unhappy with the lack of information (IGN Facebook) One of the messages left on their wall....

The problem is the confusion created by that kind of news. We refer to the page sismo_hierro Canary Islands Government. The note tells of deformation in a station in the NW of the island in its northern part, which one?. But in the data page of IGN GPS data has  not been updated since October 28. Furthermore, it is literally impossible to see a representation of  deformation distances in the the north. When we say  provide all data, that is precisely what we ask, among other things, deformation in three areas: east, north and vertical, as  any monitoring service should show. What is shown now is an act of faith and mistrust. Complete and accurate information is communication and this is responsible for education. An educated population knows how to act responsibly.

EMU moved to El Hierro material logistics to supplement its staffing on the island



01-11-2011... 20: 04 - Ministry of economy, finance and security


It is part of the preventive security device established last September


The emergency military unit, at the request of the direction of the Plan of Civil protection by risk volcanic Canary Islands (PEVOLCA), has moved to the iron material logistics to supplement its staffing on the island, which will remain stored in cantonment of Anatolian forts (Valverde)


This material would enable a permanent shelter to provide accommodation to people who might be evicted to a predictable volcanic eruption. The strength of this hostel consists of shops, dining and services for 2,000 people and complement which installed Red Cross can stay between the two to 2,500 people.


The transportation to the island of El Hierro is going to make two trips. 17 Trucks have been used in the first shuttle up tonight at the port of the stake.


This shipment of materials by the EMU, is one element of the preventive security device that is enabled on the island, according to the different phases which has passed the earthquake and volcanic phenomenon that develops from the summer.

En el blog de Jon Fremman han dejado el siguiente comentario: They have really upped the level of things they are doing the last 24 hours. It seems like someone kicked them in the nuts and explained the risk of things.
 It all started when Prof Sagiya from Nagoya (Now I got it right) opened his mouth and told them that it is risky. Now all of a sudden they are moving in troops, material and equipment for evacuations, shelters and what nots.
 I guess that Prof Sagiya has talked very hard and fast with them. ¿Sabe alguien algo sobre esto?

The Institute Volcanológico de Canarias (INVOLCAN) has confirmed, this morning, at the direction of the Civil Protection Plan by volcanic risk (PEVOLCA) an increase in the diffuse emission of carbon dioxide (CO2) into the atmosphere by the volcanic island of El Hierro once finished building his tenth scientific field campaign and evaluated the results of this parameter of interest for volcanic surveillance. The rate of registered emission has reached the 1044 ± 31 tons per day, the largest value observed since the beginning of the magmatic revival which is registering in El Hierro.


From on July 21, 2011 the INVOLCAN has been materialized more than 6,500 measures of diffuse flux of carbon dioxide (CO2) through 10 scientific field campaigns covering each building volcanic island subaéreo of El Hierro (278 Km2) with the aim of contributing to the improvement and optimization of volcanic monitoring. Highlight in this task they have collaborated and collaborate an important collective of volunteers resident in the Canary Islands.


The registration of the diffuse emission of carbon dioxide (CO2) by El Hierro Island volcanic building since last July 21 goes from the 331 ± 16 1,044 ± 31 tons per day. Following the work of diffuse emission of carbon dioxide (CO2) made in El Hierro by the ITER volcanológico Group since 1997, now at the heart of the INVOLCAN, is has been established that the average value of the diffuse emission of carbon dioxide (CO2) by the volcanic edifice island of El Hierro is of 340 tons per day, and whose normal values range from the 140 to the 885 tonnes per day. Prior to the underwater eruption that occurred southwest of La Restinga rate of diffuse emission of carbon dioxide (CO2) exceeded the range of values considered normal by registering some 990 ± 49 tonnes per day on October 6, 2011.


The graph and the results may not be disclosed or reproduced without the permission of the INVOLCAN.

Update 01/11 – 23:30 UTC :
 Harmonic tremor is further increasing. Harmonic tremor is one of the most important pre-eruption signals. It is is still not as strong as it was before the opening of the Las Calmas / La Restinga vent, but if it continuous to grow tomorrow it can be meaningful.

New volcanic eruption off El Hierro
0 Comment(s)Print E-mail Xinhua, November 2, 2011
Adjust font size:


The underwater volcano off the coast of the island of El Hierro begun erupting on Monday evening, which saw it expel steaming fragments of magma to the surface of the ocean.

The volcanic activity has returned after a series of seismic events had raised fears of a second eruption following the previous volcanic activity which began on October 10.

However, it has come as a surprise given that the experts monitoring the situation had assured earlier on Monday that although another eruption was likely, it was not going to happen in the near future.

It has also been commented that any second eruption could occur off the north coast of the island, following a distortion of the crust that had been discovered in that area.

The first signs of the new eruption were a deepening of the stain in the sea which was created by the first eruption off the most westerly of the Canary Islands

Meanwhile El Hierro suffered another earth tremor of 3.9 on the Richter scale Monday night. It was the last of a series of 70 tremors registered over the course of the day and the strongest felt on the island since the start of the seismic activity.

El Hierro, an autonomous community of Spain, is the smallest and farthest south and west of the Canary Islands, in the Atlantic Ocean off the coast of Africa.

Closer to another eruption

The seismic surge heralds a departure of lava from the larger town of El Hierro - defence reinforces the contingent to respond to a possible emergency


R. d. -Madrid-02/11/2011


The iron is coming every day towards a new eruption. Although the scientists managed to what happens with the magma below ground with great uncertainty, indirect signs (increase in earthquakes and release of gas) point toward a replay of the recorded phenomenon on October 10, this time possibly in the North of the island and its largest municipality, border, 4,000 inhabitants.

More than 11,000 tremors. Special

Return to the summer. Special


THE PROVINCE / DLP
LAS PALMAS DE GRAN CANARIA
Iron is prepared for eventual transfer mass of people to a hostel, where the tremors that occur in the North of the island, near the border, resulting finally in a volcanic eruption. Yesterday the emergency military unit, at the request of the direction of the Plan of Civil protection by volcanic risk in the Canary Islands (Pevolca), moved to El Hierro material logistics to supplement its staffing on the island, which will remain stored in cantonment of Anatolian forts (Valverde).


This material would enable a permanent shelter to provide accommodation to people who might be evicted to a predictable volcanic eruption. The strength of this hostel consists of shops, dining and services for 2,000 people and complement which installed Red Cross can stay between the two to 2,500 people.


The transportation to the island of El Hierro was performed in two trips. In the first transfer, that it planned to arrive yesterday evening to the puerto de La Estaca, 17 trucks have been used. This shipment of materials by the EMU, is one element of the preventive security device that is enabled on the island, according to the different phases which has passed the earthquake and volcanic phenomenon that develops from the summer.


Two scenarios


The development of the seismic phenomenon of El Hierro is surroundings in two different situations. Thus, according to reports from scientists at the University of Cádiz, and in reference to the deformation of the ground, continue two distinct scenarios. South of the island shows a remission in the increase of deformation, clearly marked by the eruptive process and evidence in the data recorded in the GPS station of La Restinga.


In the North of the island, on the other hand, an increase in the Northern component and to a lesser extent in the East, directed by an acceleration recorded in the GPS station situated in the Northwest of the Gulf is seen in deformations.


On the other hand, the level of tremor increased slightly over last Monday in the closest stations to the eruptive fountain, sign that earthquake activity is increasing in the new area of conflict.


The population is still closely and with concern what is happening, attentive to the tremors they feel in their homes. Thus, Cecoes 112 received during the night of October 31 near a dozen calls from dwellers of Tigaday, El Mocanal and El Matorral Guarazoca, located in different parts of the municipalities of Valverde and border. In addition the Coordinator Centre recorded also during the morning and yesterday morning some calls from the areas of Guarazoca and Los Llanos, located in the municipalities of Valverde and El Pinar respectively. However, there were no incidents involving these telephone care.


The hostel which is expected to mount seeks a transfer of persons less improvised and more organized than the carried out after the previous eruption. On that occasion were used already existing infrastructure, not a hostel as announced now.

Update 02/11 – 09:09 UTC :
 The UME  (Unidad Militar de Emergencias = Military Emergency group) has announced that it has transported the necessary equipment to El Hierro to build a shelter with a capacity of 2,000 people, in case that a quick evacuation would be needed. The equipment was brought to El Hierro on the request of Pevolca. The shelter will have all necessary compartments like  shops (...),  dining room and services.
 Material to install a shelter to accommodate 500 people and belonging to the Red Cross is already on the island, ready to be used immediately.
 PEVOLCA has stressed that the shelter equipment is one of the many measures to be prepared if a worst case scenario would come true.
 The shelters have not been installed so far because nobody knows the location where an eruption would be occurring, if it would occur. The most probable spot would be the current eruptive Las Calmas eruption crater as showed on the Ramon Margalef topographic 3-D image below, but the current set of earthquakes are occurring below the El Golfo bay. Pevoca is this prepared for everything.

Important Data update 02/11 – 08:27 UTC
 Rather constant but still strong harmonic tremor (might change after the strong quake).
 The magnitude 4.0 earthquake occurred a little while ago and is the strongest earthquake since the 4.4 earthquake on October 8. The earthquake occurred at a depth of 20 km in the bay of El Golfo. The earthquake was of course felt by the islanders.

A possible eruption in the north may be more problematic than in the south, not only for the affected population. The ocean floor is covered with the remains of a huge landslide that occurred millions of years ago (clearly visible from the ground). This accumulation of material can impede the exit of the gases from the volcano at the same time can promote landslides.http://www.elpais.com/articulo/sociedad/cerca/erupcion/elpepisoc/20111102elpepisoc_2/Tes


Landslides have the capability of causing a Tsunami for the Islands as they have done in the past so this is worrying. Luis Ignacio Gonzalez de Vallejo, Professor of Geological Engineering from the Universidad Complutense de Madrid said  that in the Canary Islands there have been waves of up to 50 meters created by large landslides

At last its being aired on Canarian Tv they are having a meeting again this morning because of the latest 4.00 earthquake.

The eruption in El Hierro volcano continues as it has been doing for past few weeks with little change. The first eruption vent that did open south of El Hierro Island has continued to erupt. But so far no Island has formed and it is unclear if it is going to form, as the depth is great in this area. Since yesterday around 06:00 UTC the harmonic tremor has been increasing. But this suggests that new vents have opened up in the south eruption area. I got some pictures of that yesterday in the email. But they did not show anything new in my view. Thanks to the readers how did send me those pictures.

The current fluctuation in the harmonic tremor from El Hierro suggests that magma is on the move in the north part of El Hierro Island. Both off the coast and maybe inland on the Island where earthquakes have been taking place. It is impossible to know how this is going to develop during the next few hours to days. As that depends on the rock structure of El Hierro Island and earlier eruptions.

Earthquake activity

During the past two weeks the earthquake activity have been growing in the North-west part of El Hierro Island. The reason why this is happening is that a new fissure is about to open in this area. As I have mentioned before in earlier blog posts. When and where is impossible to know for sure. The largest earthquake so far took place this morning, it size was ML4.0 with the depth of 20 km. But this is the automatic data from IGN. This pattern of earthquake activity is most likely going to continue during this eruption process in El Hierro volcano. Since the eruption type here is a fissure eruption.

It is worth noting that earthquakes in once place does not mean that the eruption is going to happen in that place. As the magma can travel in dikes all over the El Hierro Island and show it self anywhere on the Island it self. So the general risk is high in my opinion. The only action that can be taken is to be prepared for sudden eruption of new vents on El Hierro Island. Since there is a good amount of magma on the move inside El Hierro volcano.
