A magnitude 6.4 earthquake struck Papua New Guinea, according to the U.S. Geological Survey, occurring at a depth of about 64 miles and approximately 30 miles from Kainantu. This region, located along the Pacific Ring of Fire, is known for its seismic activity due to the interaction of the Pacific Plate with surrounding tectonic plates. Residents in the affected area live in a mix of vulnerable and earthquake-resistant structures, and recent quakes have led to secondary hazards like landslides and liquefaction.
