The activity is still ongoing.

Click on the link below yesterdays and todays earthquakes are listed on the left hand side.

It includes a 2.1 west of Lanzarote in the evening of 28th.

Thanks for all your continuing updates Jand. 


I'm waiting with interest to see what comes out of the 'disaster practice' later this year - especially the communication methods with the citizens in the event of a real situation! From what I can gather at the moment we are all meant to spend all day, every day, watching Canarian TV in case something should happen!

[jand]

I just hope the islanders now realise what could happen in the future but doubt it very much some still do not realise (or want to believe) that they live on an island where the volcano is becoming more active .

My friend has a property in Tenerife and she tells me that everyone is saying to her there is nothing to worry about.

The new update by Enrique is worth reading.

"Note 341.- Seismicity in the central building teide pico viejo, in addition to a swarm in the area of the south dorsal, Tenerife, Canary Islands, Spain. 31/01/2020.-today drawing the main seismic alignments I have taken a surprise, I have appeared some parallel alignments in ne-SW directions placed on the central building teide pico-Viejo, one aligned with the teide and another with old beak that we could Be indicating a series of efforts throughout the area with traction and displacement efforts considering the n-s efforts and breakage and decompression considering the e-w efforts.

This would not be meaningful if it was not because if it compares to the following diagram (which would have to turn 90º) would see the decompression cracks on the right, which occur for example when there is a settlement of a building, identical To those who appear in the teide building, which also indicate a movement or displacement of a portion of the island to the east (E) regarding another portion of the island to the West (w).

But this graphic does not end there marks a crack of breakage and decompression that I have marked with a circle and that could equate to the area of the swarm in the area of vilaflor, in the south dorsal, where it would facilitate the entrance of the magma or intrusion Of magma through these areas of fractured character of character. Let's see what GPS stations say in the next few days and that happens with the seismicity in the area, the truth is that these alignments are of the most interesting.

1.- the most interesting part starts in the first alignment of microsismicidad in the South-Southwest Skirt of the teide itself are a series of 4 Microdisks at a depth of 4-5 km from yesterday, in area that does not I had moved to the date so evident so far, next to the base of the hydrothermal system of the teide, which has also moved and where it ends that alignment of microdisks and whose listing I put below.

2.- the second alignment on its part is in the area of Pico Viejo, in a parallel alignment to first, but with a big difference, the 3 Microdisks (one of them even negative) are located deeper to A depth of about 11-14 km in the area where the north wall of the magmatic chamber of the caldera of ucanca is.

3.- and of course, the swarm of the area of vilaflor, in the south dorsal of Tenerife that has returned to move antesdeayer and how, with up to 14 Events located between 7 AND 9 Km, to add a couple of them more deeper to 10 and 11 km:

In the rest of Tenerife and surroundings, there are some more localized earthquakes or earthquakes, which end the SEISMIC PANORAMA BY ADEJE, arico and a pair in the area of the volcano in the middle. This starts and could get very interesting in the next few days and weeks.

Well, we keep watching, that it's not little, these days with more information from the ign that has put seismograms with more resolution, with the sign in short period (to see what last) and with the full spectrogram until 40 Hz, all a novelty. To say this was already seen in Maci, but not in the rest of seasons, something is something and it will be good for everyone.... (Enrique)"

"VICENTE PÉREZ

Tenerife is one of the most famous volcanic islands in the world, product of eruptions for tens of millions of years from the seabed and inhabited today by a million people plus tourists who visit it (they exceeded 6 million last year ). The stratovolcano of Teide is the third largest in the world if its height is taken into account from the seabed (7.5 kilometers). There are few eruptions on the island, on a human time scale, the last in 1909 (El Chinyero), and from time to time there are increases in underground signals (earthquakes, gases ...) that remind us that it is a territory volcanically active

Well, the truth is that Tenerife, in 2020, still lacks an action plan against this risk, from the perspective of civil protection. Although it is under development on behalf of the Cabildo to a multidisciplinary team.

t was the group of Podemos in the Cabildo that in 2016, with CC and PSOE in the island government, denounced that the island lacked this plan, and urged to prepare and approve it, since it is a legal obligation since 1996, and lack This document for this type of emergency was "a serious political irresponsibility."

The lack of a plan was controversial in 2016 after denouncing it We can

The then Minister of Environment and Security, the socialist José Antonio Valbuena (now Counselor for the Fight against Climate Change and Territorial Planning in the Canarian Government) responded that Tenerife had sufficient control mechanisms and emergency plans to serve the population and it was referred to the monitoring done by Involcán (Volcanological Institute of the Canary Islands) supported by the Cabildo, of the seismic activity of the Island, as well as to the Special Territorial Plan for the Prevention of Risks of Tenerife ”. The National Geographic Institute (IGN) is the one that, legally, is responsible for volcanic surveillance in Spain, and has increased in recent years the study of the bowels of the island.

But this last plan cited, as the then spokesperson of Podemos in the Cabildo replied at the time, basically proposes to locate the facilities and equipment of the Cabildo outside risk areas, “but does not establish measures of self-protection, prevention or organization of the population in case of volcanic emergency ”.

Third meeting of the Cabildo-ULL technical commission that prepares the plan

The truth is that later the Cabildo commissioned the preparation of this document and such is so that the area of ​​Security of the island corporation, which runs Cayetano Silva and that depends on the Ministry of Natural Environment and Security, has maintained this week the third of the work meetings of the Multidisciplinary Technical Commission of the Cabildo for the works of the exactly called Action Plan against the Volcanic Risk of Tenerife (PAIV), a document that is essential in the management of emergencies related to possible eruptions on the island and that in The present is in the process of projection.

"We live on a volcanic territory, in the last six hundred years there have been 16 eruptions in the Canary Islands, so we can not leave any circumstance of action to chance in the face of a new possible volcanic activity," Silva said in a statement. And he added that “for this reason we must have studied and planned all the actions that must be implemented, always attending to the procedures that from the Canary Islands Government are established in the Special Plan against the Volcanic Risk of the Canary Islands PEVOLCA, which we could say, He is the father of our plan. ”

These sharing meetings are held periodically with the agents involved in civil protection emergencies, from municipal, employer and worker representations, firefighters, different areas and services of the Cabildo itself. This week's appointment came for the sharing of the chapter dedicated to the processes of evacuation, shelter and supply of the population.

The Cabildo recognizes that in an eruption the number evacuated "can be very high"

"In the event of a volcanic emergency, the number of people who can be evacuated can be very high," Silva said, "and although there has not even been any eruption - that is, there are only warnings - the transport processes , accommodation and supply must be very well parameterized and protocolized, and we are in this work ”.

Geologists are concerned about the increase in volcanic danger due to the intense urbanization and large population that the island has had, which would multiply the possible damage with respect to past eruptions. Population evacuation needs would depend on where the volcanic episode occurred and also on meteorological factors such as wind direction. But better safe than sorry, when it comes to the forces of nature.

The drafting of this plan is being carried out between the Cabildo de Tenerife and the Disaster Risk Reduction chair. Resilient Cities of the University of La Laguna, at the head of which is the geologist Carmen Romero. "We must bear in mind that in all the eruptions that have occurred in the Canary Islands there has been an evacuation of the population, spontaneously or in a controlled manner," Romero explains in the Cabildo press release, so that they reached the point of settlement of the islands at present "a possible evacuation of the population and its relocation in shelters must be protocolized, although due to the nature of these Events, this protocol must be flexible".

“As far as volcanoes are concerned, we can talk about actions in which the population is involved for a long time, we must remember, for example, that the last volcanic activity in Lanzarote lasted seven years”, back in the 18th century, according to This expert.

The last volcanic eruption occurred in 2011 in El Hierro, where it was necessary to evacuate the 500 inhabitants of the town of La Restinga, in the municipality of El Pinar. This volcanic crisis allowed us to gauge how to deal with an extreme situation of this type on a small scale, and it was evident that there were aspects to improve on how to act in these cases not only the emergency services but also the affected population, as well as the media themselves as to how the information should be transmitted in these circumstances, so as not to generate unjustified alarms or, at least, not beyond those necessary.

No signs of a short-term eruption, according to Involcan and IGN

That said, it should be remembered that volcanologists do not signal a possible short-term eruption. Last year, Itahiza Domínguez, a physicist at the IGN, said that "The volcanic situation on the island of Tenerife is stable, but you need to study the Teide further." This Canarian researcher coordinates the Multiteide project, the largest study carried out so far on the Tenerife stratovolcano. His diagnosis was reassuring.

The coordinator of the Vulcanological Institute of the Canary Islands (Involcan), Nemesio Pérez, during a course for journalists organized last year in collaboration with the Association of the Press of Tenerife, explained that the probability of a new eruption in the Canary Islands is, in percentage terms, 94.5% in one century, 76% in 50 years, 25% in 10 years, 13% in five years and 2.8% in one year. In the case of Tenerife, this probability is even lower: just over 1% in a year, 5% in five years, 10% in a decade, 42% in half a century and 66% in a century, «percentages that would increase if there would be a volcanic reactivation process

But this geological phenomenon is not, by far, the greatest natural risk to the lives of its inhabitants, since those killed in floods by rains are counted by hundreds in the last five centuries while volcanism, with 16 eruptions, has caused as At least 23 deaths, and of these, 16 were killed not by pyroclasts or lava flows but by earthquakes related to the eruption of Arafo in 1705.
