Data type: Geological report

Groups: Seismic activity – Volcanic tremor – Plume height – Reversal of deformation – Subsidence – Earthquakes felt

Since the last statement, 177 earthquakes have been located in the area affected by the volcanic reactivation of Cumbre Vieja, 25 of these earthquakes have been felt by the population. The largest earthquake is the one located at 2:21 p.m. on the 27th, with a magnitude of 4.8 mbLg and a depth of 37 km, which has been felt with a maximum intensity of IV on the island. 9 earthquakes have been located at depths around 30 km, the rest of the hypocenters of the period are located at a shallower depth, around 12 km. The amplitude of the volcanic tremor signal is maintained at medium-high levels, with no intensification pulses. It is estimated that the column height was 2600 masl at 7:45 UTC on 27th October. GNSS stations confirm that the uplift previously recorded has reversed. However, the southern deformation recorded by the station has only partially recovered. At the most remote stations, a slight deflation is maintained (IGN, 2021).

This video taken on the 28th of October shows the slow creeping of an 'A'ā lava flow. Sourced from IGME (2021).
