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 (IGN, 2021). Tall lava fountains were observed from two vents today. Also, another new vent opened on the north west flank and effused lava at a high rate (GVP, 2021).
