2024-08-22 18:32:08 UTC (2024-08-22) · approx. 4:32 AM UTC+10 local
On August 22, 2024 at 18:32 UTC, a magnitude 5.1 shallow crustal earthquake struck 62 km NNW of Rabaul, Papua New Guinea, at a depth of 10.0 km and coordinates -3.6804°, 151.9429°. This earthquake was detected by 73 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
