Felt by 1 person across nearby locations.
On December 21, 2022 at 05:35 UTC, a magnitude 5.1 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -38.7190°, 77.9868°. This earthquake was detected by 69 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
