2022-12-26 03:13:09 UTC (2022-12-26) · approx. 1:13 PM UTC+10 local
On December 26, 2022 at 03:13 UTC, a magnitude 5.0 intermediate depth earthquake struck 94 km ENE of Finschhafen, Papua New Guinea, at a depth of 72.4 km and coordinates -6.0916°, 148.5577°. This earthquake was detected by 109 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
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.
