M4.5 Earthquake near Mid-Indian Ridge — October 25, 2023
2023-10-25 23:01:49 UTC (2023-10-25) · approx. 3:01 AM UTC+4 local
On October 25, 2023 at 23:01 UTC, a magnitude 4.5 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -14.4636°, 66.0312°. This earthquake was detected by 25 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
