4/10/2020 - 15:30h Canary Islands. - DETACHMENTS IN THE TEIDE, SWAMMERS IN TENERIFE, AND THE ACTIVITY IN THE PALM REPUNTS SOMETHING WITH A SENSE Earthquake. - On Saturday we started with a spillway on the northern side of the Teide, and this week we have had many movements throughout the archipelago, highlighting the swarm that has been in Tenerife and in the Palma, we go parts:
TENERIFE LEAKING: - A person who was this Saturday ON October 22, 2022 in the municipality of Icod de los Vines, in the north of Tenerife, has captured a small spillage in the Teide, occurred at about 12:48 hours.

In particular, the witness was able to see how the detachment took place, when he took out the cell phone and was able to record how the earth was falling: "It took a little while to get the cell phone out, but between the clouds you can see the earth. Then I took a picture of the earth scattered in the air," this person explained to NOTICE DAILY.

Interesting article from Involcan, I put the direct link, but it no longer works for reasons unknown to me, and it's the usual, something already mentioned in this space many times, which is confirmed. Just feeling that many called us alarmists and other less pleasant pearls.

Yes, although there was very very lucky in the early days of the eruption and we had no victims, the fact that it was known that it was going to erupt, where, with modeled scenarios of lava and more, the traffic light was not turned up, people were not warned, you do not know the informed them to prepare and they were not given time to avoid material, animal and sentimental damage.

What I feel most is that political-technical responsibility for this fact has evaporated like a fart in the air and nothing has changed for the next eruption, where the same will happen and we will see if luck is with us or against rio is one human disaster. This has got to change. (Enrique)


''The Volcanological Institute of the Canary Islands (INVOLCAN) within the framework of an international scientific collaboration with the University of Granada and the Trofimuk Institute of Petroleum Geology and Geophysics of the Siberian Branch of the Russian Royal Academy of Sciences, located in the city of Novosibirsk , has just published the first structural model of the Island of La Palma associated with the recent eruption of Cumbre Vieja in 2021. This work published in the prestigious journal Scientific Reports, of the Nature group, represents the culmination of a multi-institutional and international relationship focused on in knowing the dynamics of this eruption of such high social and scientific impact.For this, it was necessary to coordinate an enormous field work deploying and maintaining seismic stations as well as the enormous dedication of time involved in the analysis of seismic data to interpret the path followed by the magma from the depths to the surface.

This work began parallel to the eruptive process, obtaining the first 3D images of the interior of the Earth under the Island of La Palma two weeks after the eruptive process began. In fact, these first images, still unpublished, were presented and analyzed by INVOLCAN within the scientific committee of PEVOLCA in order to make an assessment and forecast of the ongoing eruptive process and thus help or contribute volcanic emergency management.

One of the main results of this work is the fact that for the first time the existence of a large magma reserve under the island of La Palma has been determined, which fed the eruptive process of Cumbre Vieja in 2021, and which could potentially feed new similar processes in the future. In addition, it has been possible to verify the path followed by the magma to the surface, helping to understand the reason for the high seismicity that added a higher level of risk and anguish to the population. It is an unprecedented milestone because it has been possible to effectively monitor the entire eruptive process, but inside the Earth. Finally, these results serve as a model for possible eruptions on other islands of the Canary archipelago, especially those that could occur on the island of Tenerife, because it represents a change in the paradigm or pre-established model on the internal structure of the Canary Islands. The possible existence of large magma reserves under the islands is verified, which means that the possible eruptive scenarios can take place more quickly and more explosively than what has been postulated until now with classical models.''

Apparantly Spain are starting an emergency siren beep to a mobile.

The one who warns is not a traitor: If you hear a beep on your mobile, it is that you are receiving, as a test, the new Civil Protection catastrophe and/or emergency alert system. By the way, a system that has been operating in the USA for years

Enrique, from what I see, the palm volcanoes and the Teide are different.... and it seems more damn that last one.... can it be explosive? like Stromboli?

Author
Volcanes y Ciencia Hoy - Volcanoes and Science Today.

Pedro Prestel Well yes, the volcano in the center of Tenerife is a colossus, the third largest on the planet and can be very explosive, more than Stromboli, even more than the Vesubian that ravaged Pompeii, is what happened 180,000 years ago and is known as the er choice of "the Coat".

A new study by Geociencias Barcelona of the CSIC (GEO3BCN-CSIC) assesses the impact that an episode of multiple extreme Events would have on Tenerife today . This publication, led by the GEO3BCN-CSIC predoctoral researcher, Marta López Saavedra, reconstructs the last great cascading geological event that took place on the Canary Island 180,000 years ago to analyze what consequences it would have if it occurred today .

From the Institute of Volcanology of the Canary Islands (Involcán) they have shared a video in which they show how their research staff extract lava samples without suffering burns thanks to the lava itself, which "sometimes" offers "the perfect protection" to take samples.
When lava flows offer 'perfect protection' for scientists to sample hot rock
"Extreme geological Events are natural phenomena ( volcanic eruptions, earthquakes, landslides or tsunamis ) of low probability, but high impact, which represent a risk for today's society due to their difficulty in predicting them. These episodes, which can produce chain effects and have a significant impact at a local and global level, are potentially likely in volcanic islands , such as the Canary archipelago", says the GEO3BCN-CSIC in a statement published this Wednesday.

This latest work, published in the Journal of Geophysical Research: Solid Earth , aims to predict the potential scope of a succession of extreme cascading Events that would occur during a caldera-forming eruption similar to the one that occurred 180,000 years ago in the eruption of El Abrigo .

Joan Martí, a researcher at GEO3BCN-CSIC, Jose Luis Rubio, from the Autonomous University of Barcelona, ​​and Karim Kelfoun, from Laboratoire Magmas et Volcans at the Université Clermont Auvergne in France, have collaborated in preparing this study.

According to the results of the work, the scenarios obtained show that the main urban centers and the possible evacuation routes of Tenerife would be affected , since they could be covered by the deposits of the pyroclastic flows and probably by the fall of ash.

In addition, the seismicity concentrated in the central part of the island during a collapse event in the central part of the volcanic edifice, such as the one that occurred 180,000 years ago, would produce "catastrophic" effects in various parts of the island and trigger a "devastating" landslide in the Icod Valley . This slide, in turn, would produce a tsunami that would probably have a severe impact not only on the north and west coasts of Tenerife but also on other coasts of the Canary archipelago .

"Currently, the Tenerife volcanic system is not in a situation similar to that of the last caldera eruption. In fact, reaching the conditions for an eruption like El Abrigo can take thousands to hundreds of thousands of years. ", emphasizes Marta López Saavedra, main author of the article entitled Cascading Effects of Extreme Geohazards on Tenerife (Canary Islands) . And, she adds, "at the current stage, the Teide and Pico Viejo volcanoes still seem too young to reach these conditions".

López Saavedra insists that "the chances of an eruption like El Abrigo's occurring today are very low ," although he clarifies that "zero risk does not exist and unfortunately eruptions cannot yet be predicted."

Investigate to prevent
“The results obtained in our study probably show the most catastrophic scenario that can be foreseen for Tenerife. This makes it possible to establish a maximum limit to the range of situations that can occur in order to design better risk management on this island without going overboard with minor Events, or falling short in the case of Events with greater impact ”, explains the researcher in a statement . .

López Saavedra considers that this analysis will contribute to “ improving the current Emergency Management Plan for the Canary Islands (PEVOLCA) by detailing the appropriate hazard scenarios and optimizing mitigation actions long before any emergency caused by these extreme multi-hazard Events occurs. ”.

The researcher highlights the importance of implementing continuous improvements in disaster reduction policies by the agencies responsible for emergency management. "This implies more information and training for the population of the Canary Islands," she stresses.

Technological advance: key to research
To carry out this analysis , modeling software has been combined with Geographic Information Systems to simulate each event separately and, subsequently, analyze the global result of all the scenarios obtained.

The research team used the VORIS 2.0.1 software. to obtain the area potentially affected by pyroclastic density currents; a plugin for QGIS 2.14 that allows to calculate the impact of a possible Earthquake; SLIDE software from Rocscience Inc. to analyze slope stability under seismic conditions; and finally, the VolcFlow software to simulate the propagation in space and time of the possible tsunami, as a consequence of the collision of the landslide against the ocean.
