Jakarta - A powerful 7.2-magnitude quake struck at sea early Sunday off Indonesia's West Papua province, sending residents running out of their homes and other buildings, seismologists and authorities said.
A tsunami alert was issued by the Indonesian Meteorology and Geophysics Agency (BMG) but was later canceled after no waves materialized.
The quake, which hit at a shallow depth of 35 kilometres, struck at 4:43 am (1943 GMT Saturday), about 150 kilometres north-west of Manokwari, the provincial capital of West Papua, the BMG said.
The US Geological Survey put the quake at 7.6 on the Richter scale.
