A strong earthquake has rocked Indonesia's easternmost province of Papua, but there are no immediate reports of injuries or damage.

The U.S. Geological Survey said the magnitude-7.0 underground quake struck at 6:41 a.m. Tuesday (2141 GMT) and was centered 247 kilometers (153 miles) west of Jayapura, the provincial capital of Papua.

Its depth was measured at 52.9 kilometers (32.8 miles) beneath the remote mountainous region of the island.

Indonesia is prone to earthquakes due to its location on the so-called Pacific "Ring of Fire." A massive earthquake off Sumatra island in 2004 triggered a tsunami that killed 230,000 people in a dozen countries, mostly in Indonesia's Aceh province.
