Earthquake magnitudes, intensity, and quantity increase and deflation of the eruptive centre is observed.
Since the last statement, 66 earthquakes have been located in the area, and 4 were felt by the population. The largest intensity felt was due to an earthquake that occurred at 07:02 UTC today, with a magnitude 4.5 (mbLg) at 36 km depth. A total of 28 earthquakes have been located at depths around 30 km, the rest of the hypocenters of the period are located at a shallower depth, around 10 km. The volcanic tremor signal maintains a high mean amplitude, with no intensification pulses. The height of the scattering cloud measured at 08:00 UTC is estimated to be 4,000 m. GNSS Stations show that the south-southwest deformation is reversing (IGN, 2021). A vent located 300 m from the South East base of the main cone reactivated today, this generated phreatomagmatuc activity and gas-ash emissions. At this time increased phreatomagmatic behaviour was observed at the main cone (GVP, 2021).
