28 Dec The number of earthquakes reduce dramatically compared to the previous 2 days and vertical uplift recorded near the eruptive centres
The number of earthquakes reduce dramatically compared to the previous 2 days and vertical uplift recorded near the eruptive centres
The number of earthquakes recorded and felt by the population reduce
Renewed phreatomagmatic and strombolian activity
Since the last statement, a total of 77 earthquakes have been located in the area, 5 of them felt by the population. 76 of these earthquakes are located at depths 9-18 km and only one at depth around 30 km. The maximum recorded magnitude is 4.2 (mbLg) corresponding to yesterday’s earthquake at 21:11 UTC, with a depth of 11 km and a direction with intensity V. The amplitude of the tremor signal is kept at low levels.
The island’s network of permanent GNSS stations shows an elevation of about 6 cm at station LP03, which is the closest to the eruptive centers. LP01, a GNSS station located further from the eruptive centres than LP03 continues register slight deflation.
In view of the image calibrated at 08:30 UTC, an ash cloud height of 1,900 masl is estimated, and a scattering cloud in the south-southwest direction.
The height of the cone is measured obtaining a value of 1.125m. above sea level.
