2002 Eruption
An eruption of Torishima volcano was observed from a sailing ship on 11th August 2002. An overflight the following day between 1145-1245 hr revealed an ash rising from the SW crater wall of the summit crater (Iwoyama). Discolored sea water extended 20 km W of the island. The eruption widened the summit crater. The eruption finished after 10 days.
