Next Eruption on El Hierro 'Hours Away'

Scientists and observers on the Canary Island of El Hierro are expecting further seismic activity and volcanic eruption over the next few hours, according to reports by experts.

After the two undewater volcanic eruptions earlier this week, the number of earthquakes that have recorded on the Island has been reduced significantly. But the concern continues because the data that predicts the occurrence of volcanic activity is not complete and likely to produce a new volcanic eruption. According to the Centro Superior de Investigaciones Científicas (CSIC) the next eruption could occur on land. The question now is where the next activity will be and when

Professor Ramon Ortiz from the Center for Scientific Research (CSIC) commented yesterday that the only thing that can be said about the situation is that it will result in one of three things: the fissure which the magma will escape from will move south, to deeperwaters; that fissures will open further inland and twoards the coast of La Restinga; that new fissures could open up on the Island itself.

The count of earthquakes since the recent swarm began in July has now surpassed 10,000, and both the Canary Islands Volcano Institute and the National Geographic Institute (IGN) agree that the activity has not ended.

MADRID - De Spaanse autoriteiten autoriteiten hebben schepen en vliegtuigen zaterdag opgedragen uit de buurt te blijven van La Restinga op het Canarische eiland El Hierro.

Toegenomen seismische activiteit wijst er op dat een onder water gelegen vulkaan op uitbarsten staat.

El Hierro is het meest zuidwestelijke van de Canarische eilanden. De ongeveer zeshonderd inwoners van het havenstadje La Restinga zijn afgelopen week geëvacueerd.

De regionale regering van de Canarische eilanden zegt dat in de lucht boven de zee bij La Restinga vulkanische deeltjes zijn aangetroffen.

Een onderzoeksschip dat monsters verzamelde is teruggeroepen. Ook journalisten die zich in het gebied hebben verzameld, is verteld dat ze moeten vertrekken, meldt de televisiezender La Sexta

15/10/2011 @ 18:09 A new eruption has been detected on El Hierro at just 2.4 km from the coast of La Restinga and 150 meters deep, according to data provided in a press conference by Juan Manuel Santana, Director General of Security. He confirmed that there is bubbling in the sea surface and pyroclastic material floating as a result of magma flowing in shallow waters.

La Restinga returns home to the volcano glancing
The Canary Islands government announces the return to their homes of people evicted from La Restinga and the Gulf and the reopening of the tunnels Roquille,''under extreme surveillance if they return to be evacuated.''

El Pinar today applauded the president of the Canary Islands, Paulino Rivero, when it announced it wanted to hear a whole people, anxious for days. Gradually, the island of El Hierro seems back to normal, though under the watchful eye of the volcano that grows beneath the waters of La Restinga. Recent days have been very busy, where nervousness was evident in every face. Yesterday, even the rumor of the evacuation of El Pinar. Nothing is further from the truth.

Today, everything has changed, at least for now. Thus, President of the Canary Islands, Paulino Rivero, has announced that the Directorate of Civil Protection Specific Plan and Emergency Response for Volcanic Risk (Pevolca) will in the next 24 hours evicted the residents of La Restinga and The Gulf re- their homes. It also reopens tunnels Roquille to certain restrictions. Also, there will be extreme vigilance in La Restinga, if necessary by re-evacuation.

In this sense, the president explained that there would canary enough time to evacuate the basis of information that will provide the hydrophones to be placed in the port of La Restinga and the signs of the evolution of the volcanic process. This equipment will allow the position to know which is the central issue, and the direction of the crack, and could detect if it were to produce the appearance of a new source of emission.

This decision is based on reducing the level of seismicity that scientists have detected and parameters observed in the evolution of the eruptive process. In this sense, it was determined that there is no danger to the public on the current situation and that this could be extended in time from days to months.

However, the school activity will remain in El Pinar, will not be allowed to return home for bedridden people and to remain permanently transport in La Restinga.

Regarding navigation, Rivero reiterated that maintaining the exclusion zone but allow fishermen to move their boats to the port of La stake for them to continue fishing.

R8ivero Sunday again insisted on the "exemplary behavior" of the population of El Hierro and especially the residents of La Restinga, and confirmed that it would take a package of measures aimed at individuals, freelancers and small businesses have been affected the consequences of this phenomenon.

quote:

17/10/2011 @ 07:15 – Scientists and researchers studying the volcanic activity have said that if the eruption follows its course, there may be a new small island emerging within 2 weeks.

17/10/2011 @ 09:08 – Residents of La Restinga have been allowed to return to their homes after spending days relocated at a sports venue nearby, despite the eruption moving closer to the coast of the island. The authorities claim that they will have enough time to re-evacuate the population should there be a need to do so.

El Hierro supplied with extra troops and resources

The Regional Government of the Canary Islands has mobilised a unit consisting of 16 troops (thirteen policemen, two officers and a deputy) and four vehicles (two trucks, one jeep and a patrol car) to facilitate the return of the residents of La Restinga, as well as being on hand to assist in any further evacuation if required.

Meanwhile, the telecommunications infrastructure on El Hierro has been improved in the event of further volcanic activity on or close to the island resulting in further evacuations being required.

Three stations have been implemented at Taibique, La Peña and San Andres in order to monitor the situation, with a further mobile unit being available. It has also installed a radio link from Afoba to La Gomera and a VSAT satellite link from Valverde.

Furthermore, Telefonica have responded to the request of the regional government and installed an Advanced Command Post at San Andres, along with 6 extra landlines, with an extra 2 lines for the sports center of Valverde, which is being prepared as a potential evacuation post, with a further extra line being provided for the Island's Hospital.

El Hierro Volcanolgists report new island may be formed

Further to this weekends continued Volcanic eruptions off the southth-weatern coast of the island of El Hierro, and meetings held on Sunday afternoon by the PEVOLCA committee, scientists have ressumed their analysis of the activity.

The Oceanographic research ship Profesor Ignacio Lozano has left port early this morning to monitor the eruption area, in particular investigating the numerous fish killed in vacinity of the 'stain' and collecting gas and pummice samples brought to the surface.

Whilst many residents of the evacuated village of la restinga have slowly begun to return to their properties, many have chosen to remain away from home due to fears of further volcanic activity. The authorities have not ruled out that a further evacuation may be necessary at just 7 or 8 hours notice.

Volcanologists from the CSIC (Consejo Superior de Investigaciones Científicas) have also concluded that if the activity continues for a further 2 weeks then the magma production coul result in a new island being formed just 2km off the coast of la Restinga. form a new small island 2 km out of the present El Hierro coast if the eruption continues like it does today.

Research tems have ruled out the possibility that any such 'island' would be connected to El Hierro.

Meanwhile, the Directorate General of Telecommunications and Information Technologies, under the Ministry of Presidency, Justice and Equality, made during the last days, a substantial strengthening in telecommunications infrastructure El Hierro installing additional generating the necessary redundancy If the occurrence of the failure of some existing ones.

In particular, we have placed three mobile stations Taibique TETRA Network, La Peña and San Andres and there is another alert transportable station if necessary use. It has also installed a radio Afoba to La Gomera and a VSAT satellite link from Valverde.

Meanwhile, Telefonica, at the request of the Government of Canary, installed on the Advanced Command Post (WFP) regional government, located in the San Andres, six basic lines, two in the sports center of Valverde, where they are evacuees located, and one in the Hospital of El Hierro.

There is not enough magma to form a new island El Hierro

MADRID, 17 Oct. (EUROPE PRESS) -

The scientific coordinator of the Institute of the Canary Islands Volcano, Nemesio Perez, stated that in order to form another island next to El Hierro should have an eruption of magma "incredible", which, as explained, "so far is not happening ".

In an interview on National Radio, as reported by Europa Press, Perez emphasized that the eruptions that occur or have occurred in the past in El Hierro have been low index fossils. It has also indicated that "when magma instead of going by land out near the coast to 50 to 20 feet deep, will increase your explosive" because the interaction with water causes it to break and be more explosive .

However, he pointed out that the submarine fissure eruption is about 2.5 kilometers south of La Restinga and the emission occurs at about 150 meters deep. Therefore, he noted that "the most obvious manifestations of this rash are those rocks or floating material as a result of gas content that exists in the lava."

On the other hand, has indicated that "the hydrophones that have been possible to detect which in turn allow the eviction" and noted that "volcano monitoring is based on monitoring of seismic activity, deformation and gas" and with that information "could detect any change in volcanic activity."

Finally, he stressed that "the recovery of the marine system could be quite rapid, especially the smaller species."

El Hierro Volcano 'entering a new phase'

Volcanologists on El Hierro beleive that the Volcano moved into a new phase on Momnday afternoon following signs of a number of volcanic tremors, which could indicate that the processis moving faster than originally predicted.

The Sulfur stain coming from the eruption in the Atlantic to the south of the island of sulfur is almost bigger than the island itself, and yesterday saw an increased number of bubbles rising to the surface.

Scientists predict that if things continue at the same rate huge columns of smoke may be produced, reaching some 500 feet, after high pressure steam and gas is released from the seabed, followed by explosions caused by magma at 1,200 degrees coming onto contact with seawater on the ocean floor.
The Professor Lozano research vessel of the Canary Institute of Marine Sciences (ICCM) returned to port on El Hierro late yesterday to review data, but it became clear that the lava still contains a high concentration of gases after lava rocks collected were found to break easily due to a large number of bubbles in them.

The decision made following Sunday's PEVOLCA meeting, to allow residents of la restinga to return to their homes after evacuation last week, has now been postponed until later today.

Scientists are continuing to collect samples of pyroclastic formations, fish, and water characteristics such as temperature, salinity, pH, chlorophyll, turbidity, dissolved oxygen, gases and nutrients to monitor changes in the eruption process.

The exact nature of what is happening underneath the island remains unknown for the time being, which has lead to speculation that a new formation, or 'island' may grow from the magma production 2km offshore in the Atlantic.

Towards the end of the short video clip you can see the bubbles being produced rising to the surface.

De vulkaan lijkt "Relaxed"


^{This image was produced this morning (Tuesday) and then ceased activity. Gelmert Finol}
Sergio Gutierrez, El Pinar (18.10.2011. 13:20 pm)
The area of ​​eruption has dawned calmer. At least, that the signs seem to indicate less intense than days ago that at this time can be seen in the area of ​​Los Carilo, about three miles from La Restinga and the epicenter of information these days.

According to sources consulted by AVCAN DAILY HIERRO, the decline of the tremor signal may be due to several reasons. On the one hand, the activity has ceased magna closing its output abroad, which could raise the pressure and therefore increase, again, the seismicity on the island.

It may also simply mean that the eruption has ceased, the magma is cooled in the crack, like a dam and leaving only residual seismic activity would decline.

Finally, the third possible scenario could be that the system stops cavitate or flutter, ie the area or the point where depressurization occurs is more than just size, so do not pass the magma forced by that point. AVCAN view of one form or another possibility, "would be great on curved or straight devil taking as the starting energies the stopping point of tremor".

However, it will take to the explanation of the scientists who are working on the island of El Hierro.

The Prevolca does not allow residents of La Restinga go home

The residents of the town of El Hierro La Restinga can not return home permanently, as announced by the Director General of Security and Emergency of the Canary Islands, Juan Manuel Santana and the president of the Cabildo de El Hierro , Alpidio Armas , after the last meeting held by the scientific committee Prevolca this afternoon.


Santana explained that, although the volcano eruptive activity has declined in recent hours and that the air quality in La Restinga no problems of toxicity recorded recently boosted currents by emission spot submarine to the coast by that "we must be attentive to the wind" and an increased number of tests.

Also, forward a reinforced security and controlled access area, which will increase the time that those affected can go to their homes. Weapons acknowledged the situation "embarrassing" that plagues the economy resulting from the eruption of El Hierro underwater, in reference to the fisheries sector, among others.

The director of the National Geographic Institute (IGN), Maria Jose Blanco attended the event, said that so far there has been no columns of steam and that the decreased activity could mean that the mouth of the volcano "could be closing." However, he noted that it is a hypothesis, since it is not ruled out a rash on the mainland.

White said that depends on the political representatives, and not IGN, allowing residents access to La Restinga.

Scientists needed over 48 hours whether the disappearance of the bubbles is symptomatic of the end of the eruptive process or not

President of the Canary Islands, Paulino Rivero, advanced in an interview in 'breakfasts TVE that scientists who study the phenomena of El Hierro euruptivo hope to offer a response to recent symptoms "in 48 hours." Since yesterday there is no bubbling in the sea and the intensity of the tremor has decreased.

These two phenomena could be symptoms of a "disappearance of the process or the emergence of a new point of eruption in another area," which could be on the ground.
Rivero said the inability of residents of La Restinga can not return permanently to their homes, due to security measures at the inability to determine the causes of the current phenomenon and its consequences. "It's logical uncertainty felt by the neighbors," he said, but "the priority is the safety of citizens."
The president argued that the Pevolca canary "is working perfectly" and that all measures being taken by authorities are based on the recommendations of scientists. He moved that "today you may decide to relax some," as the eviction of the residents of La Restinga or passage in the tunnel restringuido The Roquille.

19/10/2011 @ 08:00 It all seems to have gone quieter on the El Hierro eruption, the bubbling seen previously has stopped and the registered continuous tremors have decreased in intensity. Residents of the coastal town of La Restinga are only allowed to return to their homes during the day, and for a limited period of time. The El Roquillo tunnel remains open only for commercial and emergency vehicles.
