M5.0 Earthquake in the Chagos Archipelago region — January 25, 2022
2022-01-25 16:04:14 UTC (2022-01-25) · approx. 9:04 PM UTC+5 local
On January 25, 2022 at 16:04 UTC, a magnitude 5.0 shallow crustal earthquake struck in the Chagos Archipelago region, at a depth of 10.0 km and coordinates -4.4783°, 72.4395°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
