M4.6 Earthquake near Mid-Indian Ridge — September 28, 2024
2024-09-28 18:55:44 UTC (2024-09-28) · approx. 11:55 PM UTC+5 local
On September 28, 2024 at 18:55 UTC, a magnitude 4.6 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -40.0111°, 78.3125°. This earthquake was detected by 49 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.
