Ritter Island is located in Dampier Strait 9.5 km NE of Umboi Island, and 21 km west of New Britain. Ritter is the remnant of a larger island which was destroyed by an eruption in 1888.
In 1700 Dampier reported violent explosive eruptions. In March 1888 most of the island was destroyed by a catastrophic eruption. The eruption produced a 13m high tsunami which cause fatalities on Umboi, New Britain, and New Guinea.
Ritter volcano activity includes Strombolian, Pelean, and submarine eruptions.
An eruption of Ritter volcano in May 2007 produced a tsunami which hit Siassi Island (Umboi) and caused the evacuation of thousands of people.
