PANDEGLANG - A tsunami killed at least 222 people and injured hundreds on the Indonesian islands of Java and Sumatra following an underwater landslide believed to have been caused by the erupting Anak Krakatau volcano, officials said on Sunday.

Hundreds of homes and other buildings were heavily damaged when the tsunami struck, almost without warning, along the rim of the Sunda Strait late on Saturday, Sutopo Purwo Nugroho, spokesman for the disaster mitigation agency, said.

Thousands of residents were forced to evacuate to higher ground. By late afternoon on Sunday, the disaster agency had raised the death toll to 222, with 843 injured and 28 missing.

This year the vast archipelago, which sits on the Pacific “Ring of Fire”, has suffered its worst death toll from disasters in over a decade. Earthquakes flattened parts of the tourist island of Lombok in July and August, and a double quake-and-tsunami killed more than 2,000 people on Sulawesi island in September.
