End of eruption. Pyroclastic activity has ceased but low level seismic events continue.

Data type: Geological report
Groups: Seismic activity – Volcanic cone measurement

Since the last statement, 20 earthquakes have been located on the island of La Palma, none of them felt by the population. The magnitudes were between 1.3 and 2.7 (mbLg). The location of the hypocenters continues under the central area of ​​Cumbre Vieja in the same areas as in previous days; 14 earthquakes have been located at depths between 8 and 19 km, 4 earthquakes at depths less than 5 km, and 2 at depths of around 35 km. Volcanic tremors are still not observed, and seismic noise remains at levels close to the pre-eruptive period. The island’s permanent GNSS station network shows that the elevation at station LP03, which is the closest to the eruptive centres, remains at the level it reached on December 19. In the rest of the stations, no significant deformations that could be associated with volcanic activity were observed. No type of emission is observed, and the height of the cone is measured, obtaining a value of 1,122 masl (IGN, 2021).
