2022-03-16 19:55:00 UTC (2022-03-16) · approx. 2:55 AM UTC+7 local
On March 16, 2022 at 19:55 UTC, a magnitude 4.2 shallow crustal earthquake struck in the Nias region, Indonesia, at a depth of 51.5 km and coordinates 0.4971°, 98.4959°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
