A 6.1-magnitude earthquake rocked Indonesia on Sunday, centred in the far east of the country about 3,500 kilometres (2,200 miles) from the Sumatra quake disaster zone, seismologists said. The quake in West Papua province struck at 10:36 am Jakarta time (0336 GMT) at a depth of 56 kilometres, 123 kilometres 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 told AFP 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.
