M3.5 Earthquake near Samoa Islands — August 30, 2022
2022-08-30 23:28:44 UTC (2022-08-30) · approx. 12:28 PM UTC-11 local
On August 30, 2022 at 23:28 UTC, a magnitude 3.5 shallow crustal earthquake struck near Samoa Islands, at a depth of 10.9 km and coordinates -14.0964°, -169.4751°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
