Huge 6.3 earthquake hits Indonesia in Pacific region's 'Ring of Fire'

A magnitude 6.3 earthquake struck the eastern Indonesian region of Papua on Tuesday, the US Geological Survey said, but a monitor said there was no tsunami threat.

The epicentre of the quake, which struck at around 5:24 pm (0824 GMT), was around 193 kilometres northwest of the town of Abepura in Papua, USGS said.

The Pacific Tsunami Warning Center said there was no tsunami threat.

There were no immediate reports of casualties or damage.

USGS earlier gave a magnitude of 6.5 before revising it downward.
