Phreatomagic activity is reduced and strombolian activity continues.
Since the last statement, 130 earthquakes have been located in the area. 16 of these earthquakes have been felt by the population. The largest earthquake occurred at 7:27:39 (UTC) today, with a magnitude of 5.0 mbLg at 35 km, this earthquake was immediately preceded by an earthquake of 4.8 magnitude mbLg. The two quakes were felt by the populations on the island of La Palma, and in some populations of La Gomera and Tenerife but were experienced as one prolonged quake. In the period considered, 5 earthquakes have been located at depths around 30 km, and the rest of the hypocenters of the period are located at a shallower depth, around 12 km. The amplitude of the volcanic tremor signal has lower levels, without intensification pulses. The island’s network of permanent GNSS stations does not show a clear trend in the deformation of the stations closest to the eruptive centres, while in the stations further away a slight deflation is maintained, possibly related to deep seismicity. Using a calibrated image, IGN estimates a column height of 2,700 m at 07:45 UTC (IGN, 2021). Explosive activity increased around 1300, producing a dark ash plume that rose to 4.5 km altitude later in the day (GVP, 2021).
