What caused Mount Etna to erupt in 2002?
Early on the 25th November, two new explosive vents opened to the N and SSE of the 2750 m cinder cone. This caused a shift in explosive activity from the crater of the previous cone to the newly formed vents, which produced fire fountaining activity and an ash plume rising to 4.7 km elevation and spreading north.
