A 6.1-magnitude earthquake hit Indonesia on Sunday, centred in eastern West Papua province, about 3500km from the Sumatra quake disaster zone, seismologists said.

The quake in West Papua province struck at 10:36am Jakarta time at a depth of 56km, 123km northwest of the West Papua capital of Manokwari, the country's geophysics agency said.

Last Wednesday, a powerful 7.6-magnitude quake rocked Sumatra island in the west of the country, burying thousands and devastating the city of Padang and surrounding villages.

Indonesian geophysics agency technical head Suharjono said there were no immediate reports of injuries in West Papua.

"The earthquake in Papua has nothing to do with that in Sumatra. The tectonic plates in both incidents are different," he said.
