2021-02-26 20:05:22 UTC (2021-02-26) · approx. 6:05 AM UTC+10 local
On February 26, 2021 at 20:05 UTC, a magnitude 4.0 shallow crustal earthquake struck 125 km S of Kandrian, Papua New Guinea, at a depth of 10.0 km and coordinates -7.3278°, 149.7195°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
