A 5.5-magnitude earthquake shook islands in Indonesia's eastern Maluku province on Monday but there were no reports of damage or casualties, the meteorology office said.
The undersea tremor hit at 1509 IST and was centred at a depth of 40 kilometres under the sea, some 82 kilometres northeast of Namlea, the main town on Buru Island, said Jabar from the office.
The quake was felt moderately in Namlea and also on neighbouring Seram Island, he said, but there were no immediate report of damages or casualties.
Indonesia sits on the Pacific "Ring of Fire", where the meeting of continental plates causes high volcanic and seismic activity.
A 6.3-magnitude earthquake struck the city of Yogyakarta and its surrounds on the Indonesian island of Java on May 27, killing some 5,800 people.
