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.

This video taken on the 3rd of December shows slowly advancing lava flows which originate from the Northeast vent. On the Northwest of Tajogaite sulfur, deposits can be observed. Sourced from IGME (2021).
