Jakarta - A powerful magnitude 7.0 earthquake has struck the far eastern Indonesian province of Papua, US geologists said on Tuesday, although tsunami monitors said there was no threat of dangerous waves.
The quake hit at 06:41 in a remote area almost 250km west of the provincial capital Jayapura at a depth of 52km, the US Geological Survey said.
In its initial estimate, the USGS said there was "a low likelihood of casualties and damage".
It noted however that "the population in this region resides in structures that are vulnerable to earthquake shaking".
The Hawaii-based Pacific Tsunami Warning Center said there was no threat of a tsunami generated by the quake, which occurred inland underneath the Irian Jaya jungle.

The Earthquake-Report monitoring website said the area has "steep mountain ranges and its vegetation is rainforest, which means that the chance on dangerous landslides is real".
It cited specialist professor Max Wyss, who predicted between zero and 10 people may have been killed and up to 100 injured. A similar quake in April 2013 killed three people, the site added.
Geoscience Australia on its website estimated the quake could be felt up to 1 523km from its epicentre and could have caused damage up to 122km away.
The region lies on the 4 000-kilometre-long Pacific Australia plate, which forms part of the "Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.
