A volcano-triggered tsunami has left at least 222 people dead and hundreds more injured after slamming without warning into beaches around Indonesia's Sunda Strait, officials said on Sunday, voicing fears that the toll would rise further.
Hundreds of buildings were destroyed by the wave, which hit the coast of southern Sumatra and the western tip of Java about 9:30 pm (2000 IST) on Saturday after a volcano known as the "child" of Krakatoa erupted, national disaster agency spokesman Sutopo Purwo Nugroho said.
Search and rescue teams were scouring rubble for survivors, with 843 people injured and 28 missing, Nugroho said.
In September an earthquake hit the island of Sulawesi in Indonesia, triggering a tsunami. The two natural disasters devastated the region and had killed 2,000 people.
Tsunamis triggered by volcanic eruptions are relatively rare, caused by the sudden displacement of water or "slope failure", according to the International Tsunami Information Centre.
Unlike those caused by earthquakes, which trigger alert systems, they give authorities very little time to warn residents of the impending threat.
