As of Monday morning, the death toll has reached 281 in the tsunami that struck coastal areas around Indonesia’s Sunda Strait, between the islands of Sumatra and Java, on December 22, The Straits Times reported.

This is up from 222 the night before, while 1,016 people were injured and 57 were missing, according to Indonesia’s disaster agency

Also, the tsunami damaged or destroyed hundreds of homes and buildings.

The tsunami was caused by an abnormal tidal wave surge due to a full moon and an underwater landslide following the eruption of the Anak Krakatau volcano, which is located in the middle of the Sunda Strait. 

Indonesia does not have any early warning system for tsunamis.
