Earthquake magnitudes, intensity, and quantity increase and deflation of the eruptive centre is observed.
Lava spreads and prompts confinements which are later lifed as risk reduces.
Since yesterday, 102 earthquakes have been located in the area, and 7 of these earthquakes have been felt by the population. the maximum intensity being felt in the epicentral zone III-IV (EMS98), in an earthquake which occurred at 14:33 UTC on the 13th, with a magnitude of 4.4 (mbLg) at a depth of 36 km. Fourteen of the earthquakes located since the last communication were at depths around 30 km, the rest of the hypocenters are located at a shallower depth, around 10 km. The volcanic tremor signal maintains a high mean amplitude, with no intensification pulses. The height of the eruptive column measured at 6:30 UTC is estimated at 2,600 m. The island’s network of permanent GNSS stations shows uplift and warp to the south-southwest at station LP03, which is the station closest to the eruptive centres (IGN, 2021).
