Rapid increase in phreatomagmatic activity
Since the last statement, 274 earthquakes have been located in the area. 24 of these earthquakes have been felt by the population. Of all the earthquakes, 110 have a magnitude equal to or greater than 3.0 mbLg, and 4 of them have a magnitude of 4.0 mbLg. The amplitude of the volcanic tremor signal has increased considerably, with numerous intensification pulses. The column height measured at 07:45 UTC is estimated at 3,800 m. In the stations further away from the eruptive centres, a slight deflation is maintained, possibly related to deep seismicity (IGN, 2021). Strong explosive activity was observed today, 600 m tall fountains at the South East vent, and the main cone partially collapsing twice. Detached blocks rafted downslope on lava flows. Lava flows affected area previously unaffected by the lava such as Alcalá (GVP, 2021).
