Since the last statement, 90 earthquakes have been located in the area, 10 of these earthquakes have been felt by the population. At 04:41 today, the largest earthquake has taken place since the beginning of the eruption (4.6 mbLg), at a depth of 37 km, which has been felt by the population with intensity III-IV . A total of 11 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, since the last communication. The height of the scattering cloud measured at 08:00 UTC is estimated to be 4,500 m. The island’s network of permanent GNSS stations shows that both the elevation and the south-southwest deformation recently recorded at station LP03, which is the closest to the eruptive centers, have reversed.

This video shows the eruption centre which reestablished phreatomagmatic behaviour yesterday. Incandescent pyroclastic material can be seen in the centre of one of the vents. Sourced from IGME (2021).
