Two earthquakes hit eastern Indonesian regions on Sunday, but there were no reports of casualties or damage, a meteorological official said. A moderate earthquake measuring 5.4 on the Richter scale struck Papua province at 11:24 am (0224 GMT), said an official at the National Metereology and Geophysics Agency.
It was centred 147 km (91 miles) north-west of the provincial capital, Jayapura, at a depth of 78 km, the official said.
Earlier, a 5.9 magnitude quake jolted Ternate on the Moluccas islands, at 02.42 am (1742 GMT). The undersea quake had a depth of 57 km and was centred some 126 km north-west of Ternate.
Earthquakes are frequent in Indonesia, the world's fourth most populous country. Its 17,000 islands sprawl along a belt of intense volcanic and seismic activity, part of what is called the "Pacific Ring of Fire".
