On June 13, 2025 at 03:30 UTC, a magnitude 4.8 intermediate depth earthquake struck 58 km NE of Kainantu, Papua New Guinea, at a depth of 112.4 km and coordinates -5.9843°, 146.2924°. This earthquake was detected by 77 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Papua New Guinea, a region characterized by the collision and subduction of the Pacific, Australian, and Solomon Sea plates. View all earthquakes in Papua New Guinea.
