2021-12-24 21:34:02 UTC (2021-12-24) · approx. 6:34 AM UTC+9 local
On December 24, 2021 at 21:34 UTC, a magnitude 5.0 shallow crustal earthquake struck 63 km WSW of Tari, Papua New Guinea, at a depth of 10.0 km and coordinates -6.0823°, 142.4252°.
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.
