One of the theories if there is a flank collapse of Cumbre Vieja.

Update from Involcan from their Facebook page..

''Additional information on recent seismic activity recorded at the Volcano Vieja Summit (La Palma).

Since 19:01 p.m. (Canarian time) today July 25, 2020, the Canarian Earthquake Network has recorded a dozen earthquakes in the volcano Cumbre Vieja (La Palma), in addition to the 6 mainly registered on July 24, 2020, and reflected in the previous report. These earthquakes also turn out to be located at a depth of about 26 km. The highest magnitude has been 1,6 and has been recorded at 19:37 p.m. (Canarian time).

Earthquakes have not been felt by the population given their low magnitude and depth. Taking as a reference to the seismic swarms recorded at Old Summit last October 2017 and February 2018, it is likely that over the next few days there will be a low-magnitude seismic event that pose no risk to the population. We will continue to report on the evolution of this recent seismic activity recorded at the Volcano Vieja Summit.

These results have been achieved and analysed by the VOLRISKMAC projects ′′ Strengthening R & I+D+i Capacities for Monitoring Volcanic Activity in Macaronesia (MAC / 3.5 b / 124), which co - Funds the INTERREG V-A Spain-Portugal MAC (Madeira-Azores-Canary Islands) 2014-2020 of the European Commission, LPvolcano ′′ Monitoring and Research on Volcanic Activity in La Palma ′′ which finances the Security and Emergency Area and Environment of the Cabildo Island of La Palma and CAN CAN volcano that funds the Directorate General for Security and Emergencies of the Government of the Canary Islands, as well as the support of the City Council of Fuencaliente thanks to which the headquarters of INVOLCAN in La Palma is located in its municipality following an agreement signed between the City Council of Fuencaliente and INVOLCAN.''

''DEEP SOSMIC ENJAMBER ON PALM ISLAND, UNDER THE VOLCAN OLD CUMBER.- 25/07/2020-Yesterday I warned that these earthquakes could be the anterior of new seismic activity more Earthquake in the next few days., and evolution indicates that it is taking energy, yesterday I reached 2,1 and at the moment the most energetic Earthquake has reached a magnitude of 2,5, in an important series of dozens of earthquakes, many of them without locating, especially minors of 1.7 that could right now be hundreds.

Yesterday I commented that the first earthquakes looked like one of long periods or ′′ LP ′′ and it seems that something had, since then seismic activity has not stopped increasing both in number of Events and in magnitude. This gets interesting, if the seismicity continues, the next thing you would have to sing is the GPS, with a mild deformation in the next few days given the great depth to which it is occurring, with a swelling of the south of the island of La Palma, We'll see what happens.

As I said yesterday, in the earthquakes do not wait to see much, the system is with the resolution to the minimum, near a road with noise and with the clear intention that nothing can be seen, still something is seen in the Earthquake , little, but you can see. Better use the Gomera station, where you can see this afternoon's swarm between 18:00 and 19:00 UTC perfectly.. (Enrique).''

Involcan have added this video of the recent activity (which is ongoing) La Palma.

''In this animation you can see in red the hypocentres of the last seismic swarm located under the Cumbre Vieja volcano, compared to the hypocentres of the previous swarms registered in October 2017 and in February 2018 in blue.''

''MORE LOCATED SISMIC SISMIC SISMOS IN THE PALM ISLAND, UNDER THE VOLCAN OLD CUMBER.- 27/07/2020-In a policy change, clearly, the IGN has released some of the data that did not put yesterday of earthquakes that are happening under the Canarian island of La Palma, right now are already 45 localized earthquakes, that is most with a location that leaves much to be desired or deficient (look at the value of GAP, more from 200 on perimetral and not down from 100 on the whole island). especially in the Events of smaller magnitude and at sea and that does not convince anyone.

The reason for this comment is the strange distribution of earthquakes, the most magnitude in the center and surroundings those of smaller magnitude, for a very large area, it is not very credible to say.

But you have to wonder why this change, is the usual, not make a fool of yourself, because others handle better information and the video that Involcan has presented, with a much better location, with much more Events and that are placed in bunches under the volcano as expected in this type of activity on volcanic islands. The result is that they have exposed their better praxis again.

Today you see some more earthquakes in the sensor of the Gomera, possibly palm and of a magnitude between 1.8 and 1.2 that have not been located yet, maybe tomorrow.

And what will happen in the next few days? The truth is that we have two clear possibilities, the first is that possibly as other swarms will calm down, with small upsets every 15 days. Now there is also another possibility of making more noise and the hypocentres are becoming more and more somerous and loud, which would take us to another phase, a yellow light phase, no less. Now it's time to wait for him to move... (Enrique)''

''The truth is, the map viewfinder of the Canarian archipelago of IGN is like rarely, with a lot of seismic activity from the last 90 days. I haven't seen anything like this in a long time, the last two minutes ago with a magnitude 3,0 Earthquake in the volcano quite deep in the middle of 33 km and an Earthquake of magnitude 3.1 southwest of the El Hierro, also deep 30 km, almost nothing.

Latest update courtesy of Enriqiue he has commented when could be the Pevolca meeting.

I have already updated about the new swarm in my comments earlier this morning.

''And continue the seismic swarm of La Palma today... with 5 earthquakes perfectly aligned and passing through an old summit in what would be one of the bibs of this volcano. They also located some of yesterday's missing.... For when the ENVOLCA meeting, I wonder?? (Enrique)''

''MORE LOCATED SISMOS OF THE DEEP SOSMIC ENJAMBER ON THE ISLAND OF THE PALM, UNDER THE VOLCON OLD CUMBER, NAMBROQUE ZONE-TODAY black.- 29/07/2020-Follow the seismicity on the Palma Island, although The magnitude is falling and already find earthquakes around magnitude 1 and 1.3, something we didn't have a few days ago. The best place that had been available to see earthquakes is the spectrogram of the Gomera sensor, fails, - how rare - and finally we have had an Earthquake in Tenerife in the area of Icod de los Wines to finish the film, we will see if is that solo or accompany him more in the next few days.

The graphic shows that seeing the main structural lines of the island of La Palma, (form a near perfect Mercedes star centered on the boiler of Taburiente, it makes one a better idea of the matter and above all where the efforts of these days are focused watching the earthquakes of the last days, the Nambroque volcano area.

El Hierro seems to be quieter, there are no new Events located by the IGN, but as you don't see anything in the earthquakes and spectrograms (they took away the best station, CHIE), we don't know if new ones have come to produce. We'll see how this all evolves. (Enrique)''

I think Pevolca will have a meeting soon.

Guayota for La Palma


Statement from Involcan.

Translated.

''We are pleased to inform you that, starting today, a weekly graphic informative of INVOLCAN will be issued weekly on the monitoring of the earthquake-volcanic activity of La Palma. In this web link www.involcan.org/guayota-la-palma you can download the GUAYOTA-La Palma on July 31, 2020. This week we started editing it in Spanish and English. In the coming weeks it will also be provided in other languages. We edit it in color as well as in white and black for the purpose of reproducing it weekly by the media. This weekly graphic informative is prepared thanks to the LPvolcano projects, which funds the Security and Emergency Area of the Cabildo Island of La Palma, and CANvolcano, which funds the Directorate General for Security and Emergencies of the Government of the Canary Islands.''

El Hierro and the volcano of Enmedio, quieter today, without localized seismicity at the moment. In Tenerife they have located a microsism only in the area of the boiler, on the hillside of the Teide, in what would be the extension N of the Roques de Garcia.

Follow the swarm and the Pevolca still does not meet to see what they do or what measures they take, because if this swarm continues long, it will indicate the entrance of fresh magma under the island and its evolution could give many headaches, especially if it will evolve towards the surface, which would take many months, even a couple of very very busy years. We will see what happens, at the moment there is nothing more, GPS indicate nothing relevant and the gases do not know anything, nor will it be known until within a month at least, that will be the time that takes to notice the pulse when rising surface..
