Latest update courtey of Enrique.

"the activity in the last 3 months, 4 Active Centers-Tenerife, the volcano in the middle, the iron and the palm., Canary Islands, Spain.- start with an anniversaries, one of The Strongest Earthquakes Recorded in the archipelago in the area of the volcano in the middle 30 years ago with a magnitude of 5.2 to 36 km deep and that was widely felt throughout the archipelago. (Enrique)

11215 09/05/1989 02:30:37 27.9467 16.2000 36 v 5.2 2 Atlantic-Canary Islands

As for the concentration of events, and the areas of maximum tension, where they form what is known as Mercedes stars with angles to 120º tell us where the efforts are concentrated, most of them in the swarm areas .

From far away, with the seismicity of the last 3 MONTHS WE HAVE HIGHLIGHTS 4 places like Tenerife, the volcano in the middle, LA Palma and el hierro.

Closely on the island of Tenerife, you see in turn 4 places in the area of the south dorsal and the central building, focused on the teide, the swarm of the caldera, the area of mouth of tauce and the swarm of The South Dorsal, the truth is that it sums up very well what we have these last months.

And the seismic activity in Tenerife, these last 48 h the ign has located the most important earthquakes, but not the little ones, which I guess will go out as they go through the days, today they go 4 and they look More signs of earthquakes without locate, just like yesterday. We will have to keep pending, the next few days could be moved in Tenerife and surroundings, with some earthquake felt by the population. (Enrique)"

These are some comments posted in relation to the latest post by Enrique.

All have been Translated.

"The East of Gran Canaria is the 5th place, has no proper surveillance, has many noise generation points Las Palmas de Gran Canaria, the airport, all ports, the GC-1 Highway, the entire tourist area , the 2 power plants and industrial polygons.
The Fault East of the island is very active.

Ana Yanes Siverio
Ana Yanes Siverio Great post.... Enrique and thank you for always being and reporting clear and direct

Lila Ortiz
Lila Ortiz Www, this information is known to the people who live in these islands. It's to worry, how people will evict if this volcano will activate. God bless you.

Yony Torres

Top Fan
Yony Torres The situation is normal on an active volcanic island, they are right, but the danger to the population is not normal. Because anak krakatoa has a normal activity for an active island, and Gran Canaria had an explosion that killed 80 % of life on the island, and it was something normal on an active volcanicame island.
 
Keko Palma
Keko Palma Because when you look at the spectrogram of every hour of a station you see some little stripes and then you see that hour and you don't see any sign, when in the spectrogram if you see.

Yony Torres


Yony Torres The usual, don't match the graphics. When something happens, many times I want to not look at anything to know what happened in 2010 hiding thousands of earthquakes, that the less than 1'5 in energy are blocked, that lower it remove depth and frequency to lower it The magnitude, touches a lot of morality, to say it in a fine way.

you don't see the difference, you should put the truth and leave so much cover

Keko Palma
Keko Palma And The GPS equal, you look at times at night elevations of even 15 mm and the next morning there is no longer such deformation and is in normal values....

Mike Socal
Mike Socal Kekko Palma in case you pass something for a lot that you want to hide, nature is not missing, it is a shame every day, I'm glad more to give with crazy like me, the truth always comes out as much as you want to ignore .

Latest update courtesy of Enrique.

"NEW: DEEP MICROSISMICIDAD UNDER THE BOILER AND MAGMATIC CHAMBER, IN THE TEIDE AND IN THE SUMMITS OF GÜIMAR, TENERIFE, CANARY ISLANDS.- Or the improvement of the seismic network begins to allow to locate deeper microisms that before were not located or it is that we have a new activity in that area between 29 and 31 km under the Caldera de Ucanca to the SW of Pico Viejo and about 20 km under the magmatic chamber. We'll see if they do not relocate and change the data, so you still have to go with feet of lead.

It begins to notice the contour of the caldera, in the last 3 days, to microscopy of magnitude 0.3 to 12.9 km deep in the southern area of ​​the caldera next to the mouth of the tauce, where it is believed that there is the southern part of the phonolitic chamber of the central building.

Just below this chamber, two other micro-organisms of magnitude 0.2 and 0.4 have been located, the first one under the Guajara peak at 31 km and the second one under the caldera, very close to the first one in Tauce mouth of magnitude, but much deeper to 28.7 km deep. This is a novelty, because if they are well located they could indicate things like regional efforts down there, although at the moment you can not know what type.

In Case it was little, we had little efforts at the surface level in the upper part of the Valley Valley, very close to the summits area at just 2 km deep with a negative microism of magnitude-0.3, very close From the seismic detection limit of the ign, which is already much better than that 1.3 that was in 2004.

In the teide, there is also another microsismo of magnitude 0.3 located less than 1 km south of the summit in position, and 6.5 km deep in what should be the hydrothermal system of the volcano, indicating Also small efforts or presurizaciones in the system.

It is clear that these days between the seismic swarm in the area of the volcano in the middle and earthquakes in the area of the dorsal Azores and especially with a 4.2 in Madeira, the movements do not lack and of course they start to notice things on the island , with the appearance of areas of falls of stones, smells and appearance of turbid waters, all related to the possible efforts of the ground that begin to affect it.

2019-05-10 06:39:17.1 33.32 N 12.53 W 30 km M 4.2 MADEIRA ISLANDS, PORTUGAL REGION.

I finish commenting something that yesterday put in the Canary Television a video of the IGN in Youtube to reassure that it does not reassure anything at all, especially when seeing a sampling made without any care, without gloves, sitting on the fumaroles (the pants are burned) and touching everything (which is highly corrosive and burns) without protection. Of the clothes, the footwear, the TYVEX and the mask of gases just in case not to inhale dangerous gases of the fumaroles, nor we speak.
Send to see if it is normal or not to a person who seems to be their first sampling and that lack of respect to the volcano and preparation can cost you very expensive, ending in the hospital .... (Enrique) "

If you click on the link below and use the top right hand side arrows Anterior (previous)  Siguiente (Next) you can see hourly the activity on Tenerife for each day (if IGN are not down scaling the graphs).

IGN IMO are just updating the earthquakes as they wish and not showing the true extent of the activity.

To me a joke they only updated 2 earthquakes in 24 hours for the whole of yesterday.

http://www.ign.es/web/resources/volcanologia/tproximos/canarias.html

This morning a 2.1 earthquake North East of Gran Canaria.

A question to Enrique and his answer .

Translated.

"You can only describe with one word the performance of the two of the ign, and it's pathetic.
Thank you Enrique for the information. And I would like to know what your opinion is about today's new ==features==guayota."

 · Reply · See Original (Spanish) · 15h
Volcanes y Ciencia Hoy - Volcanoes and Science Today.
Volcanes y Ciencia Hoy - Volcanoes and Science Today. The Truth Adrian is that the information that reflects is different from that of ign, does not show the earthquakes aligned with the southern dorsal, but insists on the area of the central building of pico viejo and el teide, in addition to earthquakes aligned with structural failures of the Island like the ones that form the sides of the valley of la orotava and güímar.
In addition the last swarm of the middle volcano shows us the placement of the volcano in the middle to 120º, approximately, not as the ign that almost shows 90-100º, indicating that the models of land and densities used for the location of earthquakes Of both organisms are very different, this solution of involcan is much more purified, I like more than that of the ign that leaves many areas asísmicas.
Finally, as for gas emissions, no wonder they lower, long time there is no strong activity under the island, only small blips and low magnitude, so that it will only rebound if we have a swarm with several dozens Of Earthquakes of 2.5-3 or more, as a step in October 2016, October 2017 and November 2018. I'm still waiting for the next one that won't take long to arrive. (Enrique)."

"Notable Seismic Swarm this noon in the centre of Tenerife, more seismicity in the surroundings and a 2.4 in el hierro, Canary, Spain. An interesting swarm with two small localized earthquakes, the second is a very interesting earthquake of magnitude 1.6 under the caldera of ucanca to the SW of old peak at a depth of 20 km, and the other, the first is another of magnitude 1.7 in the guide area of isora at 20 km deep a few seconds before, that I don't know if you relocalizarán, but very possibly. Another also interesting is that earthquake of 1.2 in arona at a depth of 25 km under the valley of San Lorenzo, indicating tensions in the southern dorsal.

This SEISMIC SWARM, which is perfectly appreciated in Maci, we still do not know if it is of volcanic origin 100 % but it also does but confirm that in that area we begin to have a uptick of seismic activity in the appreciable area, caused by regional efforts And locals that are affecting the entire island building of Tenerife, with enough earthquakes located around the whole central building of something that seems to push up and that is available forming axes to 120º or form of star Mercedes.

The good news is that the seismicity is not yet concentrated in a specific site, with which we basically find ourselves before regional and local efforts that are affecting the central building with seismicity around it.

Note also that this afternoon we have had an earthquake of 2.4 on the island of el hierro under the coast of the julán south of the island at a depth of 19 km, nothing new, we continue. (Enrique)"

Latest update courtesy of Enrique.

Translated.

"the things of the IGN: follow regional tensions throughout the archipelago, Canary Islands, Spain.- that the ign does things, that we know all, relocate seismic events is normal, that new earthquakes are located in deferred Or spend things spent a few days, too.

Today is especially evident these things, an earthquake yesterday that disappears and several that change and are fishermen leaving a panorama, we do not know if more clear or not where you have to highlight the two earthquakes located in the area of the fonolítica chamber of the building Central that seems to indicate something, although it's soon to know.

The truth is that if you follow the earthquakes in that camera area and rise in magnitude in the next few days would indicate a clear process of possible pressurization in it, with what that would mean. It's soon and we'll have to see what happens.

As for the rest, the earthquake of magnitude 1.6 between very close to the island of la gomera at 35 km will surely be relocalicen tomorrow. The magnitude 1.1 located in the area of arico surely too. From the other two of today, the magnitude 2.8 located in the east of Gran Canaria and the magnitude 2.3 located in the northwest of Lanzarote.

For soon it must be noted that there are things I do not understand, and basically it is because there is so few data on the networks that can be accessed by all, basically in seismic, there is only 1 station on the internet, but there is Many facilities there, more than 50 seismic stations in Tenerife, including the seismic array in the plains of ucanca of the ign and enough more gadgets, but there is no access to the ign, nor to those of involcan, nor to those of the Csic and not to those of other sites, agencies or institutions.

So we are going, and it is that with all this lack of information is generating a lot of uncertainty, all controlled or leaked information and the panorama that could be presented could be much worse if the disclosure of volcanic information does not change, with possible consequences not Planned for medium-long term in the future that could affect a lot to the people of the islands and their visitors, starting with the economic, derived from a lack of management and education about the volcanic risk that will make the rumors run like gunpowder For the networks.. There I leave for today. (Enrique)"

Interesting article on Teide.

Translated.

"The Teide the only area where there could be an eruption similar to Pompeii
A Plinian eruption, highly explosive as when the Vesuvius volcano destroyed Pompeii and Herculaneum, could only occur today in the Canary Islands in the central area of ​​Tenerife, from an evolved magma chamber and residual under the Teide.

El Teide, the only area where there could be an eruption similar to Pompeii El Teide, the only area where there could be an eruption similar to Pompeii

Natural Sciences  Red Cross  Design  Volcanic eruption  U.S  Gran Canaria  Tenerife  Washington
This is indicated in an interview with Efe Julio de la Nuez, full professor of the Department of Edaphology and Geology at the University of La Laguna, and who has given a lecture on the "Explosive Vulcanism in the Canary Islands: Pliny and Hydromagmatic eruptions" in III Course of Geological Heritage of the Museum of Nature and Man of Tenerife.
     
Julio de la Nuez explains that at certain times in the Canary Islands there have been highly explosive and dangerous eruptions, such as the Plinian eruptions, which owe their name to the Roman historian Pliny, who witnessed the eruption of Vesuvius that destroyed Pompeii and Herculaneum.
       
In the Canary Islands, the only place where an eruption of this type could occur is in the central area of ​​Tenerife, in the area of ​​the Cañadas del Teide and its surroundings, because there is an evolved and residual magmatic chamber.
       
The geologist details that the most common basaltic melts come from deep layers, dozens of kilometers or more in the mantle, and usually reach the surface quickly and produce a rash with little time for that molten material to evolve.
       
But it can be, and this has happened in Tenerife and Gran Canaria millions of years ago, that these melts are paralyzed, remain in a camera or intermediate place at shallow depths -5 or 10 kilometers- for a long time and therefore evolve, that is, they change their composition to a different one: more viscous and with a higher content of gases that can generate highly explosive eruptions.
     
This is due to the fact that the basaltic melt, while cooling, loses part of its minerals, which are separated and change their composition to one with a higher content of silicas (more viscous) and at the same time accumulate more gases .
     
All this new composition does not have the previous properties "calmer" and over several thousand years it evolves to generate highly explosive eruptions.
       
The last eruptive process of this type occurred about 2,000 years ago and originated Montaña Blanca, in the vicinity of Mount Teide, details Julio de la Nuez, who specifies that a Plinian eruption like that of Vesuvius that destroyed Pompeii and that of Saint Helens volcano in the United States United could affect the entire island.
       
In Tenerife there have been highly explosive eruptions more than 200,000 years ago, in full boiling of the magma chamber under the caldera of Las Cañadas, and some devastated the island almost in its entirety.
       
A testimony of these processes are the strata of white color - produced by the fall of pumice stone - that came to cover the whole island and that are detected in areas such as Santa Cruz de Tenerife and Bajamar, in La Laguna.
     
"The good thing is that eruptions of this type are very spaced in time and are not usually long-lasting.In the case of Saint Helens in Washington, in 1980, it lasted only a few days." It was violent and rapid since in a matter of minutes a huge explosion that devastated several kilometers around the volcano, "explains the researcher.
       
In this type of eruptions there are also precursor signals that warn of the process, because the material of the magmatic chamber must be opened to 5 or 7 kilometers of depth and being viscous produces much seismicity.
