    Overview

    Ritter Island is a small, uninhabited, crescent-shaped volcanic island 100 kilometres (62 mi) north-east of New Guinea, in the Bismarck Sea, situated between Umboi Island and Sakar Island in the Morobe Province of Papua New Guinea (PNG) and close to New Britain island. It is one of many active volcanoes in PNG, which result from a subduction of the Solomon Sea plate beneath the South Bismarck Plate along the New Britain Trench. There were several recorded eruptions of this basaltic-andesitic stratovolcano in 1699 and 1793, prior to a spectacular lateral collapse which took place in 1888. Before that event, it was a circular conical island about 780 metres (2,560 ft) high.
