An increasing amount of shallow earthquakes although a low percentage are felt by the population
Since yesterday, 113 earthquakes have been located in the area, and 5 of these earthquakes have been felt by the population. The largest earthquake was the one that occurred at 4:24 UTC today, with a magnitude of 3.7 mbLg at a depth of 14 km and felt with intensity III-IV on the island of La Palma. In the period considered, 3 earthquakes have been located at a depth of around 30 km, and the rest of the hypocenters of the period are located at a shallower depth, around 12 km. The amplitude of the volcanic tremor signal continues at low-mean levels with some intensification pulses. The island’s network of permanent GNSS stations continues to show a reversal of vertical deformation at LP03, which is the closest to the eruptive centres, it remains at a lower level than previously established. On the other hand, the southwest deformation registered in the station is still continuing. In the rest of the stations, a slight deflation is maintained, possibly related to deep seismicity. Using a calibrated image, an eruptive column altitude of 1,800 m and westerly direction is estimated by IGN at 08:45 UTC. The altitude of the cone was measured, obtaining a value of 1,131 masl.
