At least 168 people have been killed and 745 injured after a tsunami hit the coast on Indonesia‘s Sunda Strait, government officials say.
The country’s disaster management agency says hundreds of buildings were damaged by Saturday’s tsunami.
It says the possible cause of the tsunami was undersea landslides after the Krakatoa volcano erupted.
The strait, between the islands of Java and Sumatra, connects the Java Sea to the Indian Ocean.
The disaster management agency warned that the death toll after the tsunami that struck at about 21:30 local time (14:30GMT) on Saturday, is likely to rise further.
Deaths have been reported in the Pandeglang, Lampung and Serang regions.
The BBC reports reports that the death toll in Lampung province alone could be in the hundreds.
Among the areas hit was the popular Tanjung Lesung beach resort in west Java. There was no warning of the advancing wave.
Footage shared on social media showed a large wave crashing into a tent in the resort, in which a popular Indonesian rock band, Seventeen, was performing. Members of the band were seen being swept away as the wave destroyed the stage.
In an Instagram video, singer Riefian Fajarsyah, said the band’s bassist and road manager had died, and that three other band members and his own wife were missing.
The country’s Red Cross said it was on the scene and searching for victims in the rubble of one collapsed building.
Sutopo Purwo Nugroho, national spokesman at Indonesia’s disaster agency, tweeted footage of the damage in Lampung.

Emergency officials are investigating whether the tsunami was caused by Anak Krakatoa, a volcanic island in the Sunda Strait.
Volcanologist Jess Phoenix told the BBC that when volcanoes erupt, hot magma pushes underground and can displace and break through colder rock. This can trigger a landslide.
But because part of Krakatoa is underwater, she said “instead of just causing a landslide, you get an undersea landslide which pushes water as it moves.” This can then cause a tsunami.
