On June 28, 2026 at 18:45 UTC, a magnitude 4.7 shallow crustal earthquake struck 39 km SW of Kandrian, Papua New Guinea, at a depth of 30.0 km and coordinates -6.4983°, 149.3410°. This earthquake was detected by 30 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
