Since the last statement, only 26 earthquakes have been located in the area. One of these earthquakes has been felt by the population. The largest earthquake was the one that occurred at 01:39 (UTC) today, with a magnitude of 4.0 mbLg at 11 km depth and felt with intensity III-IV on the island of La Palma. In the period considered, 2 earthquakes have been located at depths of 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 has low average levels, with intensifying pulses. The island’s network of permanent GNSS stations shows an elevation of about 10 cm along with deformation to the southwest between 3 and 5 November at station LP03, which is the closest to the eruptive centres. On the other hand, in the most remote stations, a slight deflation is maintained, possibly related to deep seismicity. Using a calibrated image IGN estimates a column height of 2,500 m at 08:48 UTC, with a west-southwest direction (IGN, 2021). The flow that originated along the upper south margin of the flow field has increased in advancement rate (GVP, 2021).
