A tsunami killed over 40 people and injured hundreds on the Indonesian islands of Java and Sumatra following an underwater landslide caused by the eruption of Anak Krakatau, officials said on Sunday. Hundreds of homes and other buildings were heavily damaged in the tsunami which struck along the rim of the Sunda Strait late on Saturday. It was the latest in a series of tragedies that have struck Indonesia, a vast archipelago, this year. Successive earthquakes flattened parts of the tourist island of Lombok, and a double quake-and-tsunami killed thousands on Sulawesi island. Nearly 200 people died when a Lion Air passenger plane crashed into the Java Sea in October.
