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
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.
