M4.9 Earthquake near southeast Indian Ridge — August 14, 2023
2023-08-14 07:25:26 UTC (2023-08-14) · approx. 1:25 PM UTC+6 local
On August 14, 2023 at 07:25 UTC, a magnitude 4.9 shallow crustal earthquake struck near southeast Indian Ridge, at a depth of 10.0 km and coordinates -41.1896°, 85.5050°. This earthquake was detected by 46 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
