Rapid decrease in the number of seismic events but a high magnitude is maintained.
Since the last statement, a total of 26 earthquakes have been located, 4 of them felt by the population. The maximum magnitude recorded is 3.9 (mbLg) corresponding to today’s earthquake at 7:53 UTC, with a depth of 11 km and intensity IV. In the period considered, 7 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 lower-mean levels. The island’s network of permanent GNSS stations does not show a clear trend in the deformation of the stations closest to the eruptive centres. In the rest of the stations, the slight deflation possibly related to deep seismicity has stabilized, except in LP01, which continues to register it. Yesterday at 12:50 UTC, due to the increase in the height of the eruptive column, the IGN issued a new VONA (Volcano Observatory Notice for Aviation) communicating that said height was 4800 masl.
