2022-02-12 22:49:44 UTC (2022-02-12) · approx. 8:49 AM UTC+10 local
On February 12, 2022 at 22:49 UTC, a magnitude 5.0 intermediate depth earthquake struck 129 km NW of Panguna, Papua New Guinea, at a depth of 91.5 km and coordinates -5.6589°, 154.5171°.
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.
