NEW INTENSIVE EARTHQUAKE SWARM BELOW CUMBRA VIEJA/ LA PALMA.

Data from IGN were only  barely available since the website had been changed last year. Also not much happend since then. As expected the volcano system rather cooled down  after the high activity during the last 11 years solar sun spot maximum ( 2010- 2014) has further decreased with only one but strong proton event in 2017,  and is expected to resume around  towards the next 11 yera sun spot maximum in 2022- 2024.

This  minor serial of proton events until June 2017  however had a peak event  that was extraordinary strong with  the integral proton flux raising  above 1.000 pfu for more than three days.

The immidiate heating effects on  the earth mantle however  were not as strong as during 2012- 2014 when one proton event folllowed the other accumulating their energies,( while almost all hot spots known worldwide were active)  but nevertheless could be expected to be active for a longer time maybe a half year or more

Thus the activities now occuring on several hotspots such as the Yellowstone caldera, Mt Sinabung near the  Toba caldera or as well as this  new seimic swarm measured during the past days below La Palma / Canary Islands might be  late effect of these proton events and must be taken in account in the learnng process that just has begun.

Here just some parts of a report published by the website  " the watchers" ( thanks to there!) that describes the situation well:

"A new seismic swarm started under Cumbre Vieja volcano (La Palma), the Canary Islands on February 10, 2018. Quakes in this latest swarm are stronger than those in the previous swarm in October 2017, the first swarm in this area in 30 years.

National Geographic Institute (IGN) registered a total of 83 earthquakes between 23:23 UTC, February 10 and 07:32 UTC, February 15 with magnitudes ranging from 1.6 to 2.6.

In addition, there have been several hundred more which weren't detected due to their magnitude and depth.The depth of the quakes decreased during the course of the swarm, suggesting an upward movement of magma towards the surface.

The Canary Government called for an urgent meeting of the Scientific Committee for Evaluation and Monitoring of Volcanic Phenomena to discuss why the quakes are happening again and what might happen in the future. This is the second such meeting in four months.

INVOLCAN said that this new series is something expected based on geochemical measurements made in the Cumbre Vieja volcano.
