On November 3, 2024 at 16:06 UTC, a magnitude 4.9 shallow crustal earthquake struck 201 km N of Madang, Papua New Guinea, at a depth of 21.2 km and coordinates -3.3995°, 145.8329°. This earthquake was detected by 38 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
