A strong 6.6-magnitude earthquake rocked Indonesia's Papua region on Saturday, the US Geological Survey said, but no tsunami warning was issued.
The quake struck at 10.16am (0116 GMT) at a depth of 30 kilometres (19 miles), 83 kilometres southeast of Manokwari, the USGS added, revising the magnitude down from 6.9.
"We don't yet know the impact of the quake, but so far there are no reports of damage. We know people ran out in a panic and said the shaking was quite strong," technical chief of Indonesia's Meteorology and Geophysics Agency Suharjono told AFP.
A hotel receptionist at the Mansinam Beach Resort in Manokwari reported a minute of shaking, but said she saw no damage.
"All our guests panicked and ran out of the building, but they went back after the quake was over and everything is back to normal as far as I can see," Anita, who goes by one name, told AFP.
The Papua region was struck by 5.7-magnitude aftershock at 10.24am with a depth of 10 kilometres, 83 kilometres northeast of the town Teluk Bintuni.
