ディディカス島

Didicas, 22 km NE of Camiguin Island in the Babuyanes Islands north of Luzon, was a submarine volcano prior to 1952, when a permanent island was formed. It now consists of an andesitic lava dome about 200 m above sea level and 1.4 km in longest exposed dimension. A 400-m-wide crater was formed during the 1952 eruption. The first certain submarine eruption began in 1856, building a subaerial cone that reached a height of over 200 m in 1860, but soon was eroded beneath the sea. Three rock masses up to 82 m high were left after an eruption in 1900. Two eruptions have occurred since 1952 at an explosion crater on the northern side of the island.
