Eruptive column reaches 5200 m and ash cloud spreads S-SW at 3500masl

Increase in the number of seismic events

Renewed phreatomagmatic and strombolian activity

Group: Geological report

Since the last statement, a total of 341 earthquakes have been located in the area 12 of them felt by the population. 334 of these earthquakes are located at depths 8-17 km and the rest (7) at depths from 20 km. The maximum recorded magnitude is 4.8 (mbLg) corresponding to yesterday’s earthquake at 13:04 UTC, with a depth of 37 km and direction with intensity IV. The amplitude of the tremor signal is maintained at medium levels with intensification pulses.

At LP01, the GNSS station further away from the eruptive centre, continues to register slight deflation.

In view of the image calibrated at 08:45 UTC, a column height of 5,200 masl is estimated, and an ash cloud of 3,500 masl, with a south-southwest direction.

The height of the cone is measured obtaining a value of 1,127m. above sea level.

This video taken on the 1st of December shows lava flows sourced from the northern sector of the volcano which shows strombolian activity. However, there is no lava emission from the westernmost vent which had been active almost continuously until a few days ago. point of exit or emitter focus of the main cone, which worked continuously throughout the eruption until a few days ago.
