The number of earthquakes recorded and felt by the population reduce
Renewed phreatomagmatic and strombolian activity
Since the last statement, a total of 35 earthquakes have been located on the island of La Palma, only one of them felt by the population. Most of the earthquakes (28) are located at depths between 10 and 15 km. However, two surface quakes were recorded near the western sector of the volcanic edifice. The maximum recorded magnitude was 3.5 (mbLg) corresponding to yesterday’s earthquake at 11:41 UTC, with a depth of 10 km. The amplitude of the tremor signal remains at low levels and is just as stable as in previous days. The island’s network of permanent GNSS stations does not show a clear trend in the deformation of the stations closest to the eruptive centers. In the rest of the stations, the slight deflation possibly related to deep seismicity has stabilized, except in LP01, which continues to register it. Using a calibrated image IGN estimated at 08:00 UTC, an ash cloud height of 3,000 masl heading northeast. The height of the cone is measured obtaining a value of 1,123 masl (IGN, 2021). During 6-7th December lava flow advanced Westward through multiple lava-tubes and fed flows 1 and 2, and the South delta (GVP, 2021).
