A moderate earthquake struck off the coast of Indonesia on Sunday in the Molucca Sea, seismologists said.

The USGS said a 5.3-magnitude quake struck at 9.29pm (8.29pm Singapore time, 1229 GMT Sunday), at a depth of 63 kilometres and was centred 150 kilometres west southwest of Ternate, Moluccas.

Indonesia sits on the Pacific 'Ring of Fire,' where the meeting of continental plates causes high volcanic and seismic activity.
