M4.6 Earthquake near Mid-Indian Ridge — September 16, 2020
2020-09-16 02:34:22 UTC (2020-09-16) · approx. 7:34 AM UTC+5 local
On September 16, 2020 at 02:34 UTC, a magnitude 4.6 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -34.0227°, 77.6972°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
