Since the last statement, 136 earthquakes have been located in the area. 10 of these earthquakes have been felt by the population, having reached the maximum intensity in the earthquake that occurred at 17:52 (UTC) today, with magnitude 5.0 mbLg at 38 km depth. Six earthquakes have been located at depths 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 is maintained at medium high levels, with intensifying pulses. The island’s network of permanent GNSS stations does not show a clear trend in the deformation of the stations closest to the eruptive centers, while in the stations further away a slight deflation is maintained, possibly related to deep seismicity. Yesterday, October 31 at 14:40 UTC, due to the decrease in height of the eruptive column, the IGN issued a new VONA informing that the maximum height of the eruptive column was 3500 m above sea level today, an ash cloud of 3,000 m with north-northwest direction is estimated at 08:45 UTC .
