M4.6 Earthquake near Southwest Indian Ridge — June 24, 2023
2023-06-24 21:35:51 UTC (2023-06-24) · approx. 1:35 AM UTC+4 local
On June 24, 2023 at 21:35 UTC, a magnitude 4.6 shallow crustal earthquake struck near Southwest Indian Ridge, at a depth of 10.0 km and coordinates -29.2661°, 60.8846°. This earthquake was detected by 16 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
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.
