Phreatomagic activity is reduced and strombolian activity continues.
Since yesterday, 54 earthquakes have been located in the area. 7 of these earthquakes have been felt by the population, The largest earthquake was the one that occurred at 23:05 (UTC) yesterday, with a magnitude of 4.5 mbLg at 35 km depth and felt with intensity IV on the island of La Palma. In the period considered, 4 earthquakes have been located at depths of around 30 km, and the rest of the hypocenters of the period are located at a shallower depth of around 12 km. The amplitude of the volcanic tremor signal has low average levels, with intensifying pulses. The island’s network of permanent GNSS stations shows slight vertical deformation at station LP03, which is the closest to the eruptive centres. At the most remote stations, a slight deflation is maintained, possibly related to deep seismicity. Using a calibrated image, IGN estimates a column height of 3,500 m and south-southeast direction at 08:48 UTC (IGN, 2021).
