End of eruption. Pyroclastic activity has ceased but low level seismic events continue.
Since the last statement, a total of 10 earthquakes have been located on the island of La Palma, none of them felt by the population. Magnitudes range from 1.6 to 3.2 (mbLg). The location of the hypocenters continues under the central area of Cumbre Vieja in the same areas as in previous days; 3 shallow earthquakes, 3 earthquakes at depths between 11 and 15km, and 4 earthquakes at depths greater than 30km. Low-frequency (LP) events continue to be detected in the records of the island’s stations, in addition to localized volcano-tectonic earthquakes. In the last 24 hours, no volcanic tremor has been observed, keeping the seismic noise at levels close to the pre-eruptive period. Like the previous day, the network of GNSS permanent stations on the island does not show significant deformations that could be associated with volcanic activity. Using a calibrated image IGN reports that at 08:49 UTC, no type of emission can be seen. The height of the cone was measured at 1,122 masl (IGN, 2021). On the 13th of December strong explosive activity ejected bombs and lava fountains, on the 14th of December gas emissions were high and lava continued to move from the west of the base of the main cone causing small break outs near Montaña Cogote and Las Norias. On the 15th of December neither ash plume or pyroclasts were emitted by vents for the first time since September 19th, but lava in the flow flow field remained active in tubes (GVP, 2021).
