2020-06-23 15:29:55 UTC (2020-06-23) · approx. 1:29 AM UTC+10 local
On June 23, 2020 at 15:29 UTC, a magnitude 5.0 intermediate depth earthquake struck 84 km SSW of Kokopo, Papua New Guinea, at a depth of 89.0 km and coordinates -5.0213°, 151.9164°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
