El Hierro

[jand]

As far as I understand (and may be wrong) a lot of the recent conversation today is about IGN and how they have been hiding and manipulating data which even goes back 2 years ago.

Translated.

,,Let this situation which has the IGN is like being in the middle ages, and this is due to that that body has a near monopoly situation that allows you to do this, we will if we compare we are is like in the past time the node, map of isobars and thanks for that little more had, same TV meteorologists sometimes did on a Blackboard with the data that meet, but these data used, or milk, then hand opened and the data from the stations started to become visible and public and now the difference is huge, we have data in real time, historical series, modelling. some paid and some free, but accessible; and everyone can see and comment on the subject. We are the difference is abysmal, I hope that the policies of the IGN and other organisms go moving in this direction by the pressure of the people as it has already happened in other countries such as Italy, USA, Mexico and Iceland, to name a few.

By the way, I take to leave the map updated with three earthquakes we have already today that seem to show regional tensions on the island, with earthquakes aligned direction WNW - ESE.(Enrique).,

Opinion of a Spanish person on the Avcan Facebook Page. Translated.

,,I have not even asked for data, already is that will the thing, just them wrote 1 April 2013 via e-mail, instead of complaining on twitter, as I suggested the community manager of his @IGNSpain twitter account, to ask which is the policy of data scientists, and they never answered, here can see the revolutionary demand http://geomechanics.wordpress.com/.../carta-abierta-al.../.

Subsequently, I adhered to the portal of @CIVIO tuderechoasaber.com, given the tidal wave of transparency that flooded us last summer, and requested new information with questions simple and simple http://tuderechoasaber.es/.../acceso_a_datos_cientficos... which at any time has its work (on 7 August, and then September 12). What has happened with 3 requests for information, as benevolent as their current systems do not have running..

The debate still goes on that the government is burying their heads in the sand over El Hierro and trying to cover up or not being truthful about exactly what is happening at the moment.

There is an  article in La Opinion Tenerife about El Hierro listed below are the comments from Enrique Avcan which have been translated.

..The article is good, but reading it I want to sell that no problem in the island, which is a volcanic island that is quiet and calm, and the volcano is to blame for the crisis and misery...! then go volcano! don't even look at the surface and is affecting all Canary Islands, Peninsula, Europe and the whole world... is not that they are using it from scapegoat to hide what is really happening?, Srs and SARS are in crisis if they had not realized.

Policy that is following with the volcano and everything that happens to her around, trying to cover everything concerning their behavior, their data and everything what feels, hears, smells and surrounds it with I think going contranatura, that is a mistake, as in iron, turn your back to the volcano, is to deny the reality of what has the island.

The non-transparency in the transmission of data and of what happens in some organisms, the occult and erre to te erre finish does not accept that nature will do what it pleases, we like it or not, both earthquakes as the 5.1 of the other day or future volcanic eruptions in the future only can complete a form with this fitness, in a disaster human and may be material by lack of education volcanic, not knowing what to do in case of eruption (few campaigns information and little crowded for fear he will say) and by not knowing the land in which they live or worse yet, that you are visiting and not have marked or prepared nothing.

The Islanders and people that depend on the Islanders deserve something better, only I can tell you that they care a bit between if the own Islanders and above all its tourists and will have more tourists.

Put in the skin of a tourist, to see who is the handsome that gets into an island with an active volcano where there is no information, run rumors and hoaxes, and in which of course no one knows what can happen because they have no volcanic education and data... same thing erupts and I caught... thats how I can think... they are sensible and put in the skin of the tourist, you'll see that something wrong with the current model and its attitude towards the volcano.

Look but that we are back, we went from having the information almost in real time and webcam, but little was at least early, delayed it an hour on average as it is the case with the seismic data. With others is worse, simply go to update it as referred to the deformation of the ground measured at GPS stations of the island of the Meridian, which takes 3 days now without a day since last Tuesday 21, almost anything... from bad to worse.

Information clear, transparent and continuous in time about the State of the volcano, as it is the case with the meteorology would avoid all these problems and of course would make the flow of visitors to the island much bigger, that safe.

I conclude by saying that the volcano of iron has yet for several years, 5 at least (twice what has been active), with more swarms and who knows if any or some eruptions, so as soon as possible to agree to it and recycling, better for everyone, the Islanders, the rest of the Canaries and Spanish inhabitants and of course its visitors.

OT there has been a strong earthquake in Kefalonia Greece,

..A strong earthquake of 5.9 degrees on the Richter scale occurred at 15:55 hours, in Kefalonia. The focus within the framework of the Euro-Mediterranean Seismological Centre identified two kilometers of Argostoli and Lixouri seven kilometers and the focal depth was 10 km.

Vibration was felt especially in the Peloponnese, in many cities of the continental Greece, Athens, Karditsa and Larissa, while features of the quake was long.

Early reports speak of damage in Lixouri roads and old houses.

By order of the Prime Minister, Antonis Samaras, Minister of the Interior, Yiannis Michelakis, a helicopter ride military in Kefalonia, previously reached by a strong earthquake.

Vehicles fire patrol and the prefectures of Achaia, Ilia and Acarnania to find any damage caused by the earthquake.

As said you the seismologist Gerasimos Chouliaras Skai TV, the main earthquake was successful at least five replicas of intensity 4.4 to 3.7 on the Richter scale.

Meanwhile, the situation on the island after an earthquake, described the Mayor ANA-MPA Evangelos Kekatos Kefalonia.

"We are in the process of evaluation of the damage, the earthquake was felt throughout the island and caused great inconvenience to the residents. All the services of the municipality of Kefalonia are on alert and have taken to the streets. Fortunately there were no wounded only reported damage, most of the glass windows broken by shops and other articles of glass and old buildings on the island, he said.

Even Mr Kekatos said: "some areas of Kefalonia and get a job, to restore the damage, were left without electricity and garages PPC and there are rocks and landslides on rural roads."..

There has been a 2.5 earthquake near to the east coast Tenerife this morning reported on the Avcan Facebook page.


For those joining now, let know them that at 06:21:22 this morning the National Geographic Institute (IGN) located a 2.5 earthquake (mbLg) in the sea, near the coast of el Puertito de Güímar (Höfuðskáld. 28.2916 / length. - 16.2685) and a depth of 31.8 km (margin of error 3.6 km).

The calculation of magnitude was conducted with data from stations CGUI (3.4 mbLg), EBAJ (2.7 mbLg), EOSO (1.9 mbLg), TBT (2.6 mbLg), CTIG (2.5 mbLg), CFTV (2.0 mbLg), CFUE (2.7 mbLg) and EFAM (2.4 mbLg).

They did not intervene in the calculation of the magnitude Tenerife CCAN and MACI being out of service stations.

We can not offer reading from any station of the island Tenerife is without public information of any of its stations. You can see the spectrum of EOSO (Gran Canaria) at the following link:

,,CURRENTLY TRACKING AND EVERYTHING WHAT HAPPENS PROCESS EARTHQUAKE-VOLCANIC ISLAND OF IRON. -01/02/2014 - 7:00 h Canarias.

Tonight we we have released with a few earthquakes, 3 last night, and two more this morning starting with a few earthquakes in the center of the island and then activity has migrated to the west-northwest of the island, the latter, quite deep indeed.

Earthquakes yesterday, the two children line up in n-s direction and the third magnitude 1.8 is in the area of the swarm. The other two today are in the west-northwest of the island area, in the same area of 5.1. Both the n-s alignment and that deep quake, especially when they occur in the area of the Gulf, have been a symptom in other previous cycles, where were forerunners of moments with more activity, we will see what happens the next few days.

Deformation indicates that sensors in the Gulf remain stable or a slight tendency to the under-filling or collapse especially in the Centre of the island and South, something normal, although the scatter of data is greater interference with the latest weather storms that have passed over the Canary Islands. ,,

..SMALL SEISMIC SWARMS - CURRENTLY TRACKING AND EVERYTHING THAT OCCURS IN THE PROCESS EARTHQUAKE-VOLCANIC ON IRON ISLAND. -02/05/2014 - 14:00 h Canarias. Follow earthquakes, follows the seismic activity, following the earthquake and volcanic activity, and even though many insist on thinking that this has ended... we have much to see the end of this... years... at least that I'm pretty sure.

The truth is that this is not over and although we have periods of calm, the volcanic system returns to give signs of activity from time to time, today is low, and also focuses on the center of the island, in the area of the escarpment of the Gulf and peaks area, the area of los Llanillos and Malpaso pico, but indicates that something is there below that is not precisely in balance.

Yesterday we had a swarm with 3 earthquakes located nearly at the same point in the area of los Llanillos and similar depth between 1.7 and 12.2km and the same time located in the spectrogram were some more... This morning, 5 more times, emphasizing the last two that seems to be part of another small swarm, as well as some other earthquakes... everyone in the central area of the island, and aligned NNE - SSW.

Certainly seems to see earthquakes every day, that effort is from top to bottom, the first earthquakes above and then they earn in depth, curious the less both the 3 yesterday and 5 today...(Enrique)..

,,And the graphical evolution of accumulated released seismic energy. without any doubt, that the trend in the last month is increasing its activity, showing a couple of blips in the activity in the form of steps, with a slope that appears to be increasing, although we will have to wait a few days to confirm this, rather clear says this graph shows, in recent days the system has revived somewhat.

Come on, that this is nothing new, it has already done so other times... as with the data that we have of earthquakes located by the IGN we have passed almost not have earthquakes, have some localized and this is a reflection on the accumulated released seismic energy that tends to increase your rising or their rate of release in recent days.

,,CURRENTLY TRACKING AND EVERYTHING WHAT HAPPENS PROCESS EARTHQUAKE-VOLCANIC ISLAND OF IRON. -12/02/2014 - 14:00 h, Canary Islands. At the moment the seismic activity today has been located by IGN to the West of the island between 10.3 and depth 11.4km.

Map shows after a quiet January, with just concentration of seismic events in a point, indicating that earthquakes of regional efforts, there is a slight revival of the volcanic system, with a concentration of seismic events in the Centre of the island in February indicating that the process of continuous intrusion, little by little, but continuous efforts located between 10 and 12km areathe last in that area today.

If we test these observations with the IGN GPS deformation data, light swelling between 0.5 and 1 cm can be seen at several stations in the Gulf in the past six weeks, coming to net values maximum at the moment in most of them, not increase much, but does not decrease.

Also today is remarkable that possibly related to seismic activity, shown in the spectrogram of CTIG an earthquake seconds before producing a landslide in the area of the Gulf that seem to be related. This landslide of rocks we have given testimony to a beautiful photograph of William Rodriguez polished from the Mirador de la Peña and some more that have been subsequently published...

,,It is very unfortunate that this is the aspect of the CCAN station, the only National Geographic Institute is open to the public on the island of Tenerife. More unfortunate is almost always so, or damaged. And even more unfortunate is that rather than worry about solving these problems, they engage in search thousand formulas to shield information and that it cannot reach the citizen. And the same is true on the other islands of the archipelago. So, it is no surprise that us is much easier tracking the activity of any other country, including the least developed, which have a minimum idea of what is happening beneath our feet. Sad, troubling and very risky. Let us hope that someday political nuestrtos pay attention to the things that are truly important and have very directly with the security of citizens because although we live in a paradise, nature is the boss.,

The truth is that I tried putting another map, but earthquakes are out and are not... in this shows that they are close together, like a swarm and almost at the same depth around the 10 km, indicating that follows pressurizing there far, may we have some more in the area or will locate any more that could be in the pipeline as the weak seen in the spectrogram one hour before the first and one course to 06:17 h just after the first, as well as some more at 06:51 h 08:06 h, 08:08 h and 13:57 h shortly after the second UTC.

,,Una pregunta... Hoy fui a caminar por la pista que va de La Caldera hacia Santa Úrsula en Tenerife y por la parte de la Casa del agua olía como cuando estuve por la zona del faro de la orchilla en El Hierro como a huevos podridos. Y al bajar por la carretera de Colombo también me llego ese olor. ¿Son emanaciones de gases? o no tiene nada que ver. Es que en medio del monte me extrañó.A question...

Today I went to walk the track that goes from the boiler to Santa Úrsula in Tenerife and the part the water House smelled when I was in the area of the lighthouse of orchilla on El Hierro and rotten eggs. And down the road from Colombo also I get that smell. They are emanations of gases? or not has nothing to do. It is that in the midst of the mountain I was surprised.

Yesterday we had an earthquake located by the IGN in the Centre of the island of el Hierro, which aligns more earthquakes of the last few days in direction WNW - that both in the interior of the island and the sea, in the area of the beaches, and even lined up with some craters on the island in the same direction.

These regional efforts are affecting these days the island in such a way that we have small swarms when the system moves slightly or magma makes it to relocating the efforts between 9 and 13 km deep.

Incidentally that deformation graphs the IGN in Izaña GPS has been affected by the snow and cold of the storm, indicating deformations which should not be that real... but problems associated with temporary snow past.

These comments have recently been posted on Volcanocafe.wordpress.com (people commenting on this site have been following El Hierro since 2011).

..Granyia, the thinking here was that the magma did try to emerge via Tanganasoga, but that a pluton of old hardened magma barred it's way, so it found it's way out via the flank vent known as BoB. These revised localisations would seem to support that...

..Yeah, that pluton is pretty large. It showed up as a dead region of quakes that was pretty much circular, with the dominant Tanganasoga cone situated on the southern part of the almost perfect circle of no quakes.

It had quakes all around it, but almost none inside of it, The first few weeks of quakes showed that.

My guess is that it is hardened material from when Tanganasoga was last active, forming a sort of plug. If enough pressure builds to push that up as a dome... then someone really ought to start worrying.

Evidently I used Tinypic and can no longer locate the URL. I was able to poke around on my hard drive and located the rewqorked image that I had done when I was originally yammering about it.

Remember, this is an early plot of the quake set from several months ago. That area that lacks quakes, in my interpretation, could be the bottom end of a plug/dome feature that is pretty resilient to fracture. Probably the old vent that fed Tanganasoga..

There have been 2 earthquakes on Tenerife today and a lot of discussions on the internet whether these are normal or may have a connection to whats going on with El Hierro.

2.1 earthquake degrees in the interior of Tenerife

At 09:49:19 31 this morning the National Geographic Institute (IGN) located a seism of 2.1 degrees (mbLg) southeast of Realejo Alto, in the interior of the island of Tenerife (Höfuðskáld. 28.2).945 / length. -16.5431) and a depth yet determined.

For the calculation of the magnitude the IGN has used phases of the following stations: MACI 2.4 mbLg; CRAJ 2.4 mbLg; CCAN 2.6 mbLg; CGUI 2.9 mbLg; EBAJ 0.9 mbLg and EGOM 1.5 mbLg

1260739 27.02.2014 09:49:19 28.2945 - 16.5431 2.1 0 mbLg is REALEJO ALTO.ITF

Another earthquake North of Canary Islands. In this case of 2.4 degrees

At 15:42:38 14 hours in the afternoon the National Geographic Institute (IGN) located a seism of 2.4 degrees (mbLg) in the North of the archipelago (Höfuðskáld. 29.5853 / length. - 15.1456) and a deep yet determined.

For the calculation of the magnitude the IGN has used phases of the following stations: CFUE 3.4 mbLg; EBAJ 2.5 mbLg; EFAM 1.8 mbLg; CGUI 2.4 mbLg; MACI 2.2 mbLg; CRAJ 2.5 mbLg; CCAN 1.5 mbLg and EGOM 2.7 mbLg
