An earthquake of 6.1 magnitude on the Richter scale occurred on Monday morning in Indonesia's Papua province, said the Meteorological and Geophysical Bureau in Jakarta.
The quake, which hit at 09:08 am (Jakarta time), was centred 544 km northwest of Port Moresby in Papua, at a depth of 38 km. There were no casualty reports yet.
The Indonesian archipelago sits on the Pacific Ring of Fire where continental plates meet, causing frequent seismic and volcanic activity.
A moderate 5.7-magnitude earthquake had struck northwest of the Indonesian province of Aceh on February 11.
