M4.7 Earthquake near Mid-Indian Ridge — November 12, 2020
2020-11-12 07:46:02 UTC (2020-11-12) · approx. 12:46 PM UTC+5 local
On November 12, 2020 at 07:46 UTC, a magnitude 4.7 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -36.5720°, 79.2180°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
