M4.6 Earthquake near Mid-Indian Ridge — December 24, 2023
2023-12-24 17:49:44 UTC (2023-12-24) · approx. 10:49 PM UTC+5 local
On December 24, 2023 at 17:49 UTC, a magnitude 4.6 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -28.4051°, 75.1681°. This earthquake was detected by 15 seismic stations with good 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.
