New seismic swarm in La Palma.
This swarm is developing (like the last ones) in the southern part of the island, but in this case earthquakes are more harsh.
The movements are taking place in depths ranging between 7 and 13 kilometers deep and so far the most energetic Earthquake has occurred just minutes ago, it was 2,5 magnitude.
The swarm goes on and it seems so far it doesn't stop. We'll be on the lookout....

This update was at 17:45

The new seismic series located in the south of the island of La Palma, continues, showing intensification of the activity. Since its beginning at 3:18 (UTC) yesterday, the 11th, until 16:00 (UTC) today, 315 earthquakes have been detected, of which 90 have been located. The magnitude has been increasing, especially as of 15:00 (UTC), the maximum magnitude being 2.8 mbLg. The depth of the earthquakes continues between 8 and 13 km.

The IGN has intensified the continuous monitoring of the activity.

12-09-2021 10:30 UTC. New seismic series located in the south of the island of La Palma.
From 3:18 (UTC) yesterday, the 11th and until 7:23 (UTC) today, 58 earthquakes have been detected, 29 located, on the island of La Palma, all of them of small magnitude, in the south of the island, being the largest of magnitude 2.0 mbLg. The depth of earthquakes is between 10 and 13 km.

In this area of the island of La Palma, since October 2017 there have been up to 9 seismic series with similar characteristics. The occurrence of Events of this type in an active volcanic zone is within normality and does not present any risk to the population.

'' THE PALM ISLAND SISM-VOLCANIC FORWARDS PALM AND DURING THE NIGHT HAS REPUNTED (PRESURIZING IF YOU PREFERRED) WITH 6 MAGNITUDE TERREMOTES 3.0, OR MORE (3.4 maximum intensity ), We carry over 350 localized Events and they go to 2 earthquakes per minute on the web, this moves. Several earthquakes of magnitude 3 or higher have been located.

They have felt the most important and some people notify me of cracks and damage due to earthquakes or a deformation is happening as the magma moves under the island.
They have also rudely lowered the resolution of the seismogram not to alarm, and for the most important Events to be seen, that continues to record the Events that are happening.

I keep editing the Post that I already deleted once. (Enrique)

This shows how IGN have lowered the resolution compared to the original in shown in the above post.

Pevolca have been called for a meeting today.

Scientific meeting of the Pevolca for the increase in the intensity of earthquakes in La Palma
During the past night, 12 earthquakes that have exceeded magnitude 3 on the mbLg scale have been felt by the population, two of them, detected in Fuencaliente, have reached 3.4,


The new seismic swarm that began last Saturday in the south of La Palma has intensified in intensity in the last hours. During the last night from Sunday to Monday, 12 earthquakes that have exceeded magnitude 3 on the mbLg scale have been located, some of which have been felt by the population. Two of them, detected in Fuencaliente, have reached 3.4. The number of localized earthquakes has also increased. Specifically, from 00.01 am to 06.19 this Monday, September 13, 122 seismic Events have been registered by the National Geographic Institute (IGN), most in the municipalities of Fuencaliente and Mazo, and 4 in the municipality of El He passed.

The depth of the earthquakes detected in the last hours is between 7 and 11 kilometers.

From the ING they have indicated to La Palma Now that the follow-up work has been intensified ”. A meeting by videoconference of the Volcanic Emergency Plan of the Canary Islands (Pevolca) has also been convened this Monday.

The National Geographic Institute (IGN) reports this Monday that "from the beginning of the seismic series at 3:18 (UTC) on the 11th, until 8:00 (UTC)" on Monday, the 13th, "there have been 1,570 earthquakes were detected in the southern area of the island of La Palma, of which a total of 354 have been located ”.

The magnitude of the earthquakes, he adds, "has been increasing in recent hours with a maximum Earthquake of magnitude 3.4 mbLg that has been felt by the population."

The depth of the earthquakes remains between 8 and 13 km.

The IGN has intensified “the continuous monitoring of the activity”.

''PALM ISLAND ISLAND SISMOVOLCANIC HAND, CANARIAS 13/08/2021: INFORMATION RELEASURE. That you can improve the information about this swarm is clear, and on the Volcanodiscovery web they have some very interesting tools like those of released energy and the depth we used in AVCAN, and that changes the way we look at this swarm.
I'm sharing with all of you this website where graphics can be personalized quite a lot on demand for what you want. (Henry).''

La Palma volcano (Canary Islands): strong seismic swarm suggests magma intruding at depth


''A strong Earthquake swarm started under the area of La Cumbre Vieja volcano in the southern part of the Island yesterday. So far, more than 350 tremors have been detected, including 14 quakes of magnitudes above 3.0 and 226 quakes between 2.0 and 2.9.
The strongest was a magnitude 3.4 event at 00.46 am local time this morning, which was felt by nearby residents.
Most earthquakes are at shallow depths around 8-12 km, suggesting that new magma is currently intruding into a reservoir under the volcano. Whether or not this might be leading up to new volcanic activity is impossible to say at this stage, as there seem not to be other signs of significant volcanic unrest at this stage. Similar Earthquake swarms have occurred in the past as well, most recently in late Dec last year; however back then, the quakes were deeper (at around 30 km depth), which could indicate that magma has now risen higher in the volcano's underground storage systems.
La Cumbre Vieja volcano last erupted in 1971, and it is considered one of the most active volcanoes of the Canary Islands. The situation clearly merits close monitoring.''
