A strong 7.3 magnitude earthquake has struck in Indonesia's Banda Sea, but authorities say there is no tsunami threat and no reported damage.

A strong earthquake has struck in Indonesia's Banda Sea, but authorities say there is no tsunami threat.

The US Geological Survey said the magnitude 7.3 quake was centred 208km below the earth's surface. It was felt in parts of Indonesia and in East Timor's capital Dili but there were no reports of damage.

Indonesia's geophysics agency said the deep quake - originally reported as 7.5 magnitude - didn't cause a tsunami.

The Banda Sea quake was recorded shortly after a 6.1 trembler in a thinly populated area 233km west of Papua's Abepura at a depth of 20km.

Rahmat Triyono, Indonesia's head of earthquake and tsunami centre, said the Papua quake was followed by several smaller aftershocks, but there were no immediate reports of major damage or injuries.

Indonesia is prone to earthquakes and volcanic eruptions due to its location along the Pacific "Ring of Fire." A powerful Indian Ocean quake and tsunami in 2004 killed a total of 230,000 people in a dozen countries, most in Indonesia.
