JAKARTA, Indonesia - A moderate earthquake rocked parts of Indonesia's Papua province on Wednesday but there were no reports of any damage.

The 5.9 magnitude quake hit 80 miles southwest of Jayapura, the provincial capital, the U.S. Geological Survey said on its Web site.

Indonesia, the world's largest archipelago, is prone to seismic upheaval due to its location on the so-called Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin [which includes the Western coast of America]

A massive earthquake and subsequent tsunami on Dec. 26, 2004, killed more than 131,000 people in Indonesia's Aceh province alone and left half a million homeless.
