M5.3 Earthquake near Mid-Indian Ridge — June 15, 2021
2021-06-15 23:50:04 UTC (2021-06-15) · approx. 4:50 AM UTC+5 local
On June 15, 2021 at 23:50 UTC, a magnitude 5.3 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -37.2585°, 78.1064°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
