large earthquakes have slammed Papua, the easternmost part of Indonesia formerly
known as Irian Jaya, over the past two days. Immediate reports of the dead and
injured are in the tens, with the latest estimate from the Associated Press
at 26 people killed.
On the morning of Feb. 4, Papua shook for tens of seconds during a magnitude-6.0 earthquake, with an epicenter 33 kilometers deep, according to the U.S. Geological Survey (see USGS reports). Almost 48 hours later, a shallower magnitude-7.0 earthquake struck, quickly followed by several magnitude-5 and larger earthquakes within the hour. The local time for the magnitude-7.0 earthquake was 6:05 a.m. on Feb. 6.

Reuters reported that damage to infrastructure included a hospital and airport runway in Nabire, a town of 26,000, as well as felled trees and other building collapses. Indonesia is the fourth largest populated country in the world, and the largest archipelago that sits on the Ring of Fire, the volcanic and seismically active rim of the Pacific where it meets other crustal plates.
