The seismic crisis continues with no signs of slowing. More than 250 quakes large enough to be located were detected during the past 24 hours. Minutes ago, a magnitude 3.2 event at only 4 km depth occurred and was felt.
This quake can be seen on the seismic trace as the large green signal.

La Palma Island. Update

The earthquake swarm has slowed down significantly over the past 24 hours, but it is too early to draw conclusions as to whether the crisis might soon be ending or whether it will pick up again in intensity.
Seismic activity continued to migrate slightly to the northwest and quakes were mostly at depths of around 8 km, although there were also 20 quakes at only 1-3 km to the surface. The maximum accumulated deformation reached about 6 cm by yesterday, the National Geographic Institute (IGN) reported. The rate of deformation has decreased, suggesting that the recent pulse of new magma intrusion might be over.

La Palma Update

The seismo-volcanic crisis is intensifying. During the past 24 hours, earthquakes have continued to pick up both in numbers and strength.
The largest so-far quake was a magnitude 3.8 quake at 11:16 local time at 10 km depth, initially reported even as magnitude 4, but later revised. SO far, 5 quakes during the past 24 hours were recorded with magnitudes of 3 or more. All of these were felt by locals.
The increase in seismic activity is likely a sign that magma continues to intrude and push its way into deeper rock layers, thus causing the quakes. Another worrying trend is the general tendency of quakes getting shallower. Altogether, the likelihood of a new volcanic eruption continues to increase.

Is there a threat of a mega-tsunami from La Palma?
Unfortunately, some media outlets are picking up on the potential threat of a "mega-tsunami" that could be caused by an eruption on La Palma and devastate the US east coast... While this certainly is a potential scenario, it should also be said that it is the very worst case, and thus least likely scenario: by all known geological evidence, the current chance of a giant landslide from La Palma is still extremely slim, even should La Palma erupt in the near future.

Nearly all volcanic ocean islands suffer massive collapse events from time to time, and La Palma is no exception.

La Palma Update​

Eruption started at 3.15 p.m. local time​

Update Sun 19 Sep 2021 15:09
The eruption started at 3.15 p.m. local time (14:15 GMT), 10 minutes after our previous update when we noticed the strong increase in seismic activity.

Following the increasing seismic activity and the previously suspected beginning of tremor, the volcano erupted short time ago - probably much earlier than most expected.

There are not many details yet, but from initial pictures it seems that a fissure opened on the western flank of La Cumbre Vieja, feeding lava fountains and flows, burning forests and farmland.

In the meantime, seismic activity continues to increase by the minute, dominated by volcanic tremor, reflecting the flow of magma to the surface.

Oh boy 😬. FWIW, Dutchsinse’s latest report discusses the possibility of massive tsunami event that could inundate the East coast of the US should a portion of the volcano shelf collapse into the ocean.
