The marine geology  commented yesterday that there does lurk the possibility of a landslide causing a Tsunami.


..La actividad sísmica continua en las inmediaciones de la isla, amenazando con posibles episodios volcánicos, a pesar de que la incertidumbre del evento es muy alta y no sabemos ni cuando ni donde podría presentarse. Mientras escribo estas lineas se comenta en los noticieros el terremoto de magnitud 4.9 que ha sucedido este medio dia y que ha sido sentido claramente por la población. Se produjo un importante desprendimiento de ladera con caida de bloques y material disgregado en las cercanías de Pozo Perejil. Uno de los efectos inmediatos de los terremotos son precisamente los deslizamientos de tierra tan abundantes en la isla de El Hierro. No se nos oculta el riesgo tsunamigénico que afecta a la isla, en caso de producirse un importante deslizamiento en las vertientes acantiladas que dan al mar y sobre los cuales ya hay modelos matemáticos avanzados..

..Continuous seismic activity in the vicinity of the island, threatening possible volcanic episodes, while the uncertainty of the event is very high and we don't even know when or where could arise. As I write these lines discussed in the news the earthquake of magnitude 4.9 that has occurred this noon and has been clearly felt by the population. There was an important detachment of slope with falling blocks and material disintegrated in the vicinity of Parsley well. One of the immediate effects of earthquakes are landslides so abundant in El Hierro island. Not hidden us risk tsunamigenico  affecting the island, in the event of a major landslide in the steep slopes that already give the sea and about which there are advanced mathematical models...

Statement from the PP Party El Hierro 20th March.


El Hierro PP calls for prudence when it comes to inform


..Based on the experience already acquired from the day in which began the process, we know that we possess the necessary expertise as people to react to such an event.

We know that it is not necessary to create alarm before a natural fact that we have learned to live together, but not only El Hierro, but Canary Islands in general, since they are islands of volcanic origin, it is for this reason that we cannot allow that relying on such process some get their 5 minutes of glory, no matter that the economy of the entire being charged with such alarmist statements an island that has had to join a major economic crisis a earthquake-volcanic crisis.

Taking into account that we approach an important season for tourism on the island, from here we ask all those responsible technical and political, as well as to the various means of communication, both how audiovisual writings, dealing with the information with the naturalness that it requires, without alarm, and without exaggeration, since they are an open window that serves as a springboard to sell the island as a prime destination..

- Project Vulcano is sharing their daily works around the island. We truly appreciate their openness with the public, and what they shared today we bring to you, translated by Julio.

They video below shows the first stage of a project that will transmit live data to the open net of the conditions just above the volcano. Data to be broadcasted will be measured from just the top of the volcano, the cone, at 89 meters, and 15 meters above it. 2 ton weights will hopefully hold the system in place. This will include measurements of  oxygen, chemistry levels with two CTD and doppler current meters. In a around 45 days, the communication system that will transmit the data to land will be installed and soon after we will be able to monitor the situation online. Very exciting!

- TV crews and news services have gone today to El Hierro after the strong earthquakes to report on the crisis. Here is a good report from Antena 3 noticias, a national popular channel in Spain, which includes comments from Nemesio Pérez, expert from INVOLCAN. Video is, of course, in Spanish, but images shown have been recorded today.
- Interesting comment from divers at La Restinga: "When the 4.9 struck, we were diving and we heard it like a small roar, but there was no movement"..

The sound of the earthquake reaching La Palma...


just took the spectrogram of the quake..

[link to www.01.ign.es]

and made a sound file of it at 30 times the hertz shown on the chart to make it audible. interesting those divers heard a roar too.

it's also interesting that the roar at la palma is longer than at el hierro

Divers who were diving at the time of  the 4.9mb earthquake have been discussing how they felt on the radio.

Los submarinistas hablando en la radio sobre como lo sintieron... y a esto yo me pregunto..No pueden haber derrumbes bajo el mar??? En la zona donde estaban buceado y sintieron como ellos dicen esa presion en el pecho que no fue algo desmedido pero si bastante erceptible por el grupo de buceo en el que estaban. No hay nada que pueda descolgarse bajo el mar o esas zonas de buceo son completamente diafanas y llanas ? Solo es una pregunta ...

Divers talking on the radio about how they felt it... and this I wonder...There can be no landslides under the sea? In the area where were diving and felt like they say that pressure in the chest that was not something wasteful but if enough erceptible by the Group of diving in which they were. There is nothing that can sag under the sea or those areas of diving are completely sheer and plain? It is only a question...

..Increased activity led to the Security Ministry of the archipelago to activate the protection plan before volcanic risk (Pevolca) in phase of pre-emergence March 27. Since then another indicator, the seismic traffic light, is in yellow. According to the website of the Ministry, "meaning that we must prepare for an unfavorable evolution of the phenomenon, and most importantly, be aware of the official messages of prevention and self-protection that will be specific to areas of risk".

Civil protection plan implies time cutting some minor cart (HI 50 between the junction table and Sabinosa and the access road to Playa La Madera, of the Pozo de la Salud to the confluence with the HI 503) risk of landslides, and, more importantly, of the lane nearest to the mountain of the highway linking the capital of the islandValverde, with the largest city economically, the border, to the North of the island. Both locations are linked by a highway that allows you to reach one another in 20 minutes thanks to a tunnel that runs through the mountain. Two years ago, the closure of the tunnel to the risk of landslides meant a great loss, because the alternative route is through a mountain by the middle of the Island Road, that could triple the journey time.

On the other hand, the movements have not meant that it has reactivated the volcanic focus of La Restinga, to the South of the island. This town was the most affected by the onset of the phenomenon, since open mouths underwater closed the port, leaving the population without activity. La Restinga is a site that depends on Ayuntamiento del Pinar, in the interior of the island, and living from fishing and diving clubs. The population was evicted a couple of times before the risk of underwater emission gases to reach dry land.

The latest information of the Canary Islands Government are that there is a slight increase in CO2 emissions, but their values are within normal limits.

The earthquakes of El Hierro, unlike other earthquakes, are not related to movements of continental plates, but with the intrusion of an underground magma layer that struggle to get out. However, experts review current volcanic Canary Islands (Avcan), as Vicente Soler Javaloyes, volcanologist of the volcanic Canary Islands station (CSIC), said on March 21 that there seems to be enough energy so that, on this occasion, the intrusion lead to an emission of lava..

Comment from Volcanocafe re the threat of a Tsunami.

..No, you are not fear mongering Luis. I think the danger of rock fall (desprendimientos), land slides (deslizamientos) because of heavy earthquakes – as they are happening at this moment – is a serious danger for the people on Hierro. That is not just people getting hit on the head by falling rocks, but because it still includes the danger of a tsunami. Even when it's not the overrated mega-tsunami that will wipe out the US east coast, nearby beaches, villages and ports on Hierro or the other islands may get some sloshing when a piece of rock chips off due to a heavy quake, especially since the seaboard at most of these places rises up pretty steeply. Maybe it's just me, but I get the feeling the governing bodies at the Canarian Isles trivialize this danger a bit because they have gotten used to seismic activity, and nothing happened all those other times...

..Conditions physico-chemical water point situated on the underwater volcano of La Restinga, El Hierro, presented today "much higher" anomalies that the who had in December, with parameters such as the temperature of the water at the bottom, has uploaded three degrees.

This is one of the results obtained by researchers at the Spanish Institute of Oceanography (IEO) and the University of Las Palmas de Gran Canaria in the campaign "Vulcano" is being the ship "Ramón Margalef" since March 22 in El Hierro, to determine how has altered the way the underwater eruption that occurred between October 2011 and March 2012.

"Ramón Margalef" team has completed an exhaustive study on the conditions of the sea in the area of the volcano, which has made 36 hydrographic stations from the surface to the bottom to know the status of 40 parameters physico-chemical, such as temperature, salinity, oxygen, pH, or presence of CO2, among others for three consecutive days.

As reported today the IEO, the environment of the underwater volcano continues to present anomalous parameters, as already noted the oceanographic vessel "Ángeles Alvariño" last December, during the campaign Raprocan (deep Radial of the Canary Islands).

"Now, the anomalies are much higher, and there is also a significant increase in the temperature of the water tied to the Fund up to three degrees." Measured pH has been 7.4, representing an acidification of 0.5 points with respect to normal conditions", requires the scientific campaign team Vulcano, who directs the researcher of the IEO Eugenio Friar.

The sanilinidad, alkalinity and total inorganic carbon present in water also show high values with respect to normal, even though they were not detected in any significant concentrations of reduced sulfur compounds, one of the elements made by the volcano on a massive scale during the eruption and which then formed in the sea a huge green area.

Scientists have also observed that, in the absence of a definitive analysis, zooplankton communities remain "relatively normal" values of abundance and biomass, requires the IEO.

The "Ramón Margalef" just placing on top of the volcano in La Restinga, 87 metres of depth, the anchor of the buoy that within a month and a half will go in real time, and continuously the evolution of the water conditions.

Now, this ship of the IEO leaves the coast of La Restinga and goes to the maritime area located to the West of El Hierro, where are concentrated the majority of earthquakes that have occurred in recent weeks.

The Vulcan campaign, involves the Oceanographic Centre of the IEO in the universities of Las Palmas de Gran Canaria and La Laguna (Tenerife), the Spanish bank of algae and the Museum of nature and the man of Tenerife, Canary Islands..

- IEO, Instituto Español de Oceanografía, has published a press report a few moments ago that the mission of the Ramon Margalef  revealed some anomalies. The "vulcano" mission has nothing to do with the current seismic crisis and was planned many months ago. The mission is in part funded by the European Union.
The most important anomaly they found is a 3°C higher temperature at the new crater in the Las Calmas sea (this is the -87 meter submarine crater who erupted in 2011-2012). The temperature is also higher than during another mission which took place in last December which showed also anomalies. 40 (mostly chemical) parameters were examined during this mission. Some showed anomalies (see press report).

- As many of you may have seen already, the CHIE graph has been rescaled. We expect that IGN has done this to get the complete amplitude of the strongest earthquakes visible on the graph

2013-04-01 09:53 UTC
- The seismic crisis is continuing with still a lot of (mostly weaker) earthquakes at a safe distance from the coast.
- We have a special interest for 3 weaker quakes who are located at 11 to 14 km depth below the old island crater area (see map). The depth 11 to 14 km is still deep.
- 34 earthquakes listed by IGN so far today (hundreds weak or micro-quakes in reality)
- 11 earthquakes M3 or more
- strongest earthquake so far today M3.8
- These data seem small at the moment compared to the previous days but are still significant. We do however NOT like to scare people at the island when there is NO reason to do this. So far there is NO reason apart from rockfall in steep cliff areas to be afraid from. Keep away from steep cliffs is our main advise. On top of this you should ALWAYS be prepared for a major earthquake by at least fixing heavy objects in the house + read also : Be Earthquake Prepared

Pevolca insists that there are no signs of eruption enminente in El Hierro

..
The Director of the Institute of Geografía Nacional (IGN) Jose María Blanco confirmed, however, that there has been "an intensification of the recovery process", similar to that occurred in June 2011.
Sismico-volcanica crisis - 01/04/2013 RTVC web writingThe Plan of Civil protection by volcanic risk (Pevolca) ruled out an imminent eruption in El Hierro after the recent earthquakes recorded in the West of the island.

The Director of the national geographical Institute (IGN) José María Blanco confirmed, however, that there has been "an intensification of the recovery process", similar to that occurred in June 2011, which ended with a deformation of 10 cm on the ground and earthquakes with a maximum of 4 magnitude 6 on the Richter scale.

White insisted that there is no "surprise" because the parameters are almost the same as in the previous Quake-volcanic episode, at the time noted that the epicentre of these movements is situated at greater depths.

The Pevolca met Monday for more than two hours to discuss the recent earthquakes recorded on the island.

The Committee has confirmed that the island has suffered more than 2,100 seismic events in recent weeks, the vertical deformation on the island reaches a cumulative value of about 11 centimeters, while values of emission of CO2 into the atmosphere by volcanic island El Hierro building exceeded the normal values range, as it had recently spread.

The Plan maintains the semaphore of volcanic risk in the yellow part of the island, in the area bounded by the race HI-500 at the height of the Pozo de la Salud to the South, at the confluence of the HI-500 with the HI-400, at the junction of The Tomillar.

Closest to the mountainside Tunnel rail continues closed at the exit of the border, the HI 50 Road between table and Sabinosa crossing and the access road to the Pozo de la Salud playa La Madera, to the confluence with the HI-503.

The South, via the accesses to the Ermita de Los Reyes and el Sabinar HI 400, are open..

Seismicity, explained María José Blanco, still located about ten kilometers west of the coast of El Hierro and to between 15 and 20 kilometers of depth, except some more superficial moves to 2 km from the beach of the Verodal.

The movements have been recorded displacement to the South and West since its inception.

So far has been measured a deformation of 11 centimeters in this seismic turnaround, which has released energy from its start one raised to thirteen joules for ten.

Geochemical data indicate levels of carbon dioxide from 1,700 tons per day, when the normal values are between 150-890 tons.

"The data are not running to a scenario that can trigger immediately," and there are no signs of tremor, said María José Blanco in relation to a possible eruption like that took place under the sea in October 2011 near the South coast of the island.

Since the eruption, there was another seismic rebound with similar values to the current concluded without eruptive consequences, which may now be the same scenario or not, "but there is no indication that will have an immediate outcome," according to the experts.

Scientists hope to continue for the time being seismic movements in the same quantities, but cannot be a spatial or temporal framework on its evolution, said María José Blanco. .

- The PEVOLCA meeting has ended with a press conference where Maria José Blanco explained to the press that no new measures are decided.
She could not comment on the IEO reported anomalies but believed that the higher temperature may be explained as the influence of degassing.
Answering a question "what next" she said (of course) that nobody knows what will be coming but a summer 2011 scenario should not be excluded (the volcanic action below El Hierro started in the summer of 2011 and went on for about 3 months before a submarine eruption took place).
She also explained why the M4.9 yesterday was changed into a M4.6 and later again to a M4.9. It was just a matter of appropriate scales (we have explained this yesterday after the event took place). They changed it again to M4.9 when people started to make grim remarks about it (conspiracy to hide the truth)..

MEETING OF THE PEVOLCA... NOTHING NEW...(Enrique) Intensified sismovolcanica of El Hierro without data allowing to establish a prognosis of 01-04-2013 evolution continues... 04: 59 Pm - Ministry of economy, finance and security held in El Hierro civil protection measures the Scientific Committee of the Plan of Civil protection by volcanic risk (PEVOLCA) met this morning in Tenerife has concluded that data from the process of intensification sismovolcanica that is taking place in El Hierro do not allow to establish a prognosis of evolution. During the last 24 hours the seismic activity has decreased comparatively with respect to previous days, but with events of high energy, which are locating in the last 24 hours are still being located west of Orchilla, between 15 and 20 km deep, approximately 15 kilometres from the coast. Since the beginning of this new series have been located about 2,130 earthquakes, the largest of which are magnitude 4.9 registered yesterday March 31, at 10:59 (UTC)., and there has been a cumulative deformation of 11 centimeters. The anomalous values of helium 3, recorded from October 2011, as well as considered normal in the diffuse emission of CO2 doubled by El Hierro island building remain logged in relation to geochemical parameters. For the Scientific Committee, consisting of representatives of the national geographical Institute, volcanological Institute of the Canary Islands, geological survey and mining, Spanish Institute of Oceanography and the University of La Laguna, this process does not have to lead to an eruption as the occurred in La Restinga, in October 2011, since values now are similar to that reached in the reactivation of June 2012. Some 2,800 earthquakes of at least 170 were felt by the population, reaching a maximum magnitude 4.2 and accumulated deformation of 10 cm occurred in concrete between June 24 and July 15. Faced with this situation the PEVOLCA maintains civil protection measures taken last Wednesday in El Hierro given the magnitude of the seismic activity, that they are as follows: * will disable the tunnel rail closest to the slope at the exit of the border; the closure of the stretch of road between the junction table and Sabinosa HI 50 and the access road to Playa La Madera, of the Pozo de la Salud to the confluence with the HI-503. It is important to avoid transit through these areas because of the risk of landslides. * Remain open access to the Ermita de Los Reyes and el Sabinar in the southern area, HI 400 * is maintained by both the yellow traffic light of information for the population in the area bounded by the HI 500 at the height of the Pozo de la Salud to the South, at the confluence of the 500 HI HI 400 at the intersection known as El Tomillar. The address of the PEVOLCA would like to remind that in real time of the phenomenon and constant monitoring is becoming so that any change in the characteristics of the movements that involve risk would communicate immediately. Also, it is recommended to take into account the advice of self-defense in the event of earthquakes, known by all, and that can be found at http://www.gobiernodecanarias.org/dgse/descargas/sismo_hierro/autop_sismo.pdf. http://www.gobcan.es/noticias/index.jsp?module=1&page=nota.htm&id=152939

(01/04/2013 - 21:00 Kuwait, Canary Islands 19:00, 18:00 h UTC) Earthquake-volcanic swarm of iron continues to evolve, now with less energy release and updated map you can see how it is changing the pattern, already not dispersed energy as yesterday, but since yesterday at noon becomes focus Seismicity in some specific areas in the S part of the swarm, which means that this swarm continues. As regards energy, seen from the start of the swarm seems volcano relaxes and gives a truce... and I say it seems... and is than that to make the graph of the released seismic energy accumulated tonight, take me a surprise to represent only since yesterday at noon and the curve that I came out it was ascending, expected something that indicated that the system was relaxing, maybe not... indicates just the opposite a weak recovery, indicates the system after release lots of energynow does not release so much, it seems as if the estaviera saving... but increasingly loses more to take pressure, i.e. I think that continues to pressurize. So what is week and can that you part of the next, the probability of earthquakes equal or greater than 4.9 last is there, do not forget it.

..And already, one of shallow earthquakes between 0 and 5 km, in yellow every since I started in June 2011, in red that we have had in this swarm since March 1 and green both today. These earthquakes are important because they mark the areas of surface weakness where you could open an emission point. Right now two candidates, one in the area of summits between Sabinosa and Orchilla and now we must begin to consider the marine area to the West of the island, prolongation of the Summit under the sea area, where we have had 4 shallow earthquakes in the last two days.
