“Since the last statement, 135 earthquakes have been located, and 20 of these earthquakes have been felt by the population. The earthquake that occurred at 15:34 UTC on the 23rd had a magnitude of 4.9 mbLg at 38 km depth, up to this moment it is the largest earthquake since the beginning of the eruption. The 15:34 UTC 4.9 mbLg earthquake was widely felt throughout the island from La Palma and with a maximum intensity II and was felt weakly in some populations on the islands of La
Gomera and Tenerife. In the period considered, a total of 9 earthquakes have been located at depths around 30 km, the rest of the hypocenters of the period are
located at a shallower depth, around 12 km. The volcanic tremor signal maintains a high mean amplitude, with intensifying pulses.
The column height measured at 07:45 UTC is estimated to be 3,200m. Slight deflation recorded at GNSS stations further away from the eruptive centres is maintained, which is possibly related to deep seismicity.”
