At least seven people were killed after a 6.0 magnitude quake struck off the coast of Indonesia's main Java island, the country's disaster agency said Saturday.
The temblor hit offshore about 45 kilometres southwest of Malang city in East Java.
"The agency has recorded six dead and one person who sustained serious injuries," said National Disaster Mitigation Agency spokesman Raditya Jati, adding that several villages in East Java had been evacuated.
It was not clear if the toll would rise, but the agency did not report anyone missing after the strong quake.
The quake struck at a relatively deep 82 kilometres - shallower quakes tend to do more damage than deep ones.
Images from the scene showed a ceiling caved in at a hospital ward and debris strewn across the floor of the local parliament in Blitar, a city southwest of Malang.
Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire", where tectonic plates collide.
