A stronger-than-usual explosion occurred at the volcano this morning, the National Institute of Geophysics and Volcanology (INGV) in Catania reported.
At 10.08 a.m. local time, an explosive sequence of greater than ordinary intensity took place from the central-southern crater area, throwing incandescent lava bombs and lapilli to several hundred meters height and all over the crater terrace and the upper part of the Sciara del Fuoco.
An ash plume rose above the craters, quickly dispersed towards the south by strong northerly winds. The explosions were clearly visible on seismic recordings showing that the events lasted approx. 3 minutes and had the characteristics seen with other unusually strong explosions. Volcanic tremor rose temporarily to high values. Other monitoring data, in particular, deformation, showed no significant changes, and the frequency of „normal“ explosions at the various vents has not changed either.
