Volcanic activity in Canary Islands 2021

[jand]

Update by IGN at 13:00.

Translated.

Seismic activity continues to migrate slightly to the northwest, at depths of around 8 km, with 50 shallow earthquakes between 1-5 km also being recorded. The maximum accumulated deformation reaches about 10 cm.

The seismic activity started at 3:18 (UTC) on the 11th continues. As of 09:30 (UTC) today, 4530 earthquakes have been detected in the southern area of ​​the island of La Palma, of which they have located a total of 1023. Activity continues to migrate slightly in a northwesterly direction. Since 00:11 (UTC) on the 15th, 50 earthquakes have been located at depths between 1-5 km. The accumulated energy so far is 2.8 × 10 11 Joules.

The maximum accumulated vertical deformation is around 10 cm in the area close to seismicity and its distribution is still compatible with a center of pressure in this area. These movements have been observed both with the island's GNSS network and through InSAR data (Sentinel-1).

The IGN has intensified the continuous monitoring of the activity.

The IGN will continue to monitor the activity that can be followed through the Web pages:

Interesting Video sorry cannot translate it.

El experto en volcanología Vicente Soler explica en este vídeo a qué puede deberse la súbita actividad sísmica detectada en La Palma estos días (sptiembre 2021).

Proud of myself sent it to Enrique and got a thank you back.

He has been a good teacher for me and I am still trying to learn.

gracias por el vídeo, voy a verlo.

PALM ISLAND ISLAND VOLCANIC ENJOY, CANARIES 16/09/2021: INFORMATION RELEASURE.- FOURTH ENVITE. - The seismic activity or fourth upturn or envite that began this noon after a small Earthquake of brokenness or depressurization that has lasted a few hours in what is already the fourth piece of activity of this seismic swarm, where you can see many things:
1.- First thing is that it has been lighter or smoother than the previous three, it seems that the activity is going to less fortunately which does not mean a stronger one in the coming days.
2.- The depth of earthquakes takes a tendency to rise, something like half a mile daily these 5 days of swarm from 10 km to 7.5 today on average and rising... but getting tired or running out of energy today... this quieter.
3.- The reverse distribution of released seismic energy follows a downward lognormal distribution, indicating that the system loses power or runs out of energy, starting from a maximum of energy at little time when the intrusion began, which makes it think the intrusion has been on time and stops, until the next intrusion comes that will give a new swarm.
4.- The one who is stopping or slowing down the deformation is noted in the graphic of the IGN inclinometer that is seen as moderating deformation or inflation although it appears that yesterday there was still some magma contribution that has kept moving.
5.- There is no estimated eruption date possible as there is no way to calculate it by having a line or trend of downward released seismic energies. To draw an estimated date, you need a line of upward energy or ladder of the devil, with steps growing bigger and bigger and we have the opposite, steps getting smaller since it started 5 days ago.
6.- There has not been a broken Earthquake or firing of a sufficient magnitude (magnitude 4-5 or even more) to enable the eruption to reach the surface as usually happens in volcanic eruptions. We keep waiting.
We'll see what happens, what seems to be taking a break, but this is more than interesting for the next few days. Gas, deformation and seismicity will be the most interesting thing in the coming days. And it can be re-reactivated anytime in the next two weeks almost certainly with seismicity above the 3 magnitude and whether it comes strong 4 or more. (Enrique)

The Minister of Public Administrations, Justice and Security of the Government of the Canary Islands, Julio Pérez, today chaired the constitution and implementation of the Steering Committee of the Special Plan for Civil Protection and Attention to Emergencies due to volcanic risk in the Autonomous Community of the Canary Islands (PEVOLCA ) on the occasion of the seismic swarm of La Palma.

Present at this meeting were the highest representatives of the Cabildo de La Palma, the municipalities of Fuencaliente, Los Llanos de Aridane, El Paso and Villa de Mazo; the Delegation of the Government of Spain in the Canary Islands, the General Directorate of Security and Emergencies of the Government of the Canary Islands, the Canary Health Service, the Ministry of Ecological Transition, Fight against Climate Change and Territorial Planning of the Government of the Canary Islands, the Emergency Service Canario and CECOES 1-1-2. Likewise, technicians from the different administrations have been present.

The Steering Committee is constituted to analyze and achieve the best development of the actions contemplated within the action plans provided by each of the municipal, island, autonomous and state administrations.

Miguel Ángel Morcuende, head of the Environment and Emergencies service of the Cabildo de La Palma, has been appointed technical director of PEVOLCA and will be responsible for the direction and coordination of all the actions carried out under the Plan itself.


At this meeting the general situation was addressed based on the reports provided by the Scientific Committee, which also met this Thursday. The Government of the Canary Islands has decided to reinforce the Canary Islands Emergency and Security Network (RESCAN) with the increase of repeater stations, as well as communication terminals that are made available to the Technical Directorate.

In addition, it has become aware of the increase in the means of surveillance by the National Geographic Institute and the Volcanological Institute of the Canary Islands, who have deployed seismic instruments in the Cumbre Vieja area. This Friday, both the Steering Committee and the Scientific Committee will meet again.

The Plan Directorate has also recommended to the Technical Directorate the activation of emergency plans at the municipal and island level in the affected area. This alert phase of the PEVOLCA, yellow traffic light, includes the preparation of a possible evacuation of the population. In this sense, both the Cabildo and the municipalities intensify information to the population about their self-protection plans, meeting points and evacuation routes, as well as the travel needs of people with reduced mobility.

Since 04:00 this morning seven of the earthquakes have only been between 4km 3km 1km in depth .

All can be viewed on the link below.

It looks like the strength of the earthquakes has just started to increase again since 06:30

This is a worry if there is a lava flow look how the villages are placed below Cumbre Viaje just hope that they will be asked to evacuate in time .
