The US Geological Survey said the magnitude 5.6 quake was centered in the Cianjur region in West Java province at a depth of 10 kilometers (6.2 miles), ABC News reported.
It killed at least two people and injured four others, the National Disaster Mitigation Agency said. Dozens of buildings were damaged, including an Islamic boarding school, a hospital and other public facilities, it said.
Information was still being collected about the extent of casualties and damage, it said in a statement.
The quake was felt strongly in the greater Jakarta area. High rises in the capital swayed and some were evacuated.
“The quake felt so strong. My colleagues and I decided to get out of our office on the ninth floor using the emergency stairs,” said Vidi Primadhania, an employee in South Jakarta.
