2022-11-15 20:48:20 UTC (2022-11-15) · approx. 6:48 AM UTC+10 local
On November 15, 2022 at 20:48 UTC, a magnitude 4.9 shallow crustal earthquake struck 104 km SSE of Kokopo, Papua New Guinea, at a depth of 51.6 km and coordinates -5.2129°, 152.6377°. This earthquake was detected by 114 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
