The seismic activity under la Cumbre Vieja has picked up again during the past 12 hours, after having decreased significantly during the previous day.
The largest quake was a magnitude 3.2 event at 03:26 (UTC) today, at shallow depth of 0.1 km, and was felt by the population. Up to today moment and since the beginning of the series, 5391 earthquakes have been detected, of which 1102 have been located.
The maximum accumulated vertical deformation is around 10 cm in the area close to the earthquake swarm and its distribution is still compatible with a center of pressure from a magma intrusion under the same area. These movements have been observed both with the island’s GNSS network and through InSAR data (Sentinel-1).
While the seismic swarm is still far from the levels of the first days of the crisis, which had started on 11 Sep, there is a noticeable trend of quakes becoming shallower. Combined with the ongoing deformation, the chances of a new volcanic eruption are gradually becoming larger: it seems that the pulse of new magma intruding underground, causing both the quakes and the uplift of the ground, has not yet stopped.
