Phreatomagic activity is reduced and strombolian activity continues.
Since the last statement, 83 earthquakes have been located in the area. Four 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 shows a slight deformation towards the southwest at station LP03, which is the closest to the eruptive centers.
At the most remote stations, a slight deflation is maintained, possibly related to deep seismicity. Yesterday, October 30 at 19:05 UTC, due to the increase in the height of the volcanic ash cloud, the IGN issued a new VON communicating that said height reached 5,000 m above the level of the sea.
