Earthquake magnitudes, intensity, and quantity increase and deflation of the eruptive centre is observed.

Data type: Geological report

Groups: Seismic activity – Volcanic tremor – Volcanic tremor intensification pulses – Plume height – Earthquakes felt

Since the last statement, 101 earthquakes have been located in the area, and 7 of these earthquakes have been felt by the population. The maximum intensity was felt due to earthquakes that occurred at 11:06 and 23:57 UTC on the 17th, with magnitudes 4.0 and 4.6 (mbLg) at 35 and 36 km depth, respectively. A total of 35 earthquakes have been located at depths of 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 4,000 m, decreasing by 200 m from yesterday (IGN, 2021).
