The number of localised earthquakes has decreased and the Eruptive column has decreased by 500m in height but the Volcanic tremor remains high.

The number of localised earthquakes has decreased and the Eruptive column has decreased by 500m in height but the Volcanic tremor remains high.

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 the 12th of October, 66 earthquakes have been located, 6 felt by the population. Of the earthquakes located since the last communication, 5 are found at depths greater than 30 km, and the rest of the hypocenters are located at a shallower depth, around 12 km. The total number of localized earthquakes has greatly decreased. The volcanic tremor signal maintains a high mean amplitude, with no intensification pulses since the last release. The height of the eruptive column measured at 6:30 UTC is 3,000m.
