M5.3 Earthquake near Mid-Indian Ridge — April 28, 2023
2023-04-28 03:54:38 UTC (2023-04-28) · approx. 7:54 AM UTC+4 local
On April 28, 2023 at 03:54 UTC, a magnitude 5.3 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -16.4340°, 67.2028°. This earthquake was detected by 64 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
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.
