M4.8 Earthquake near Mid-Indian Ridge — October 15, 2025
2025-10-15 03:45:12 UTC (2025-10-15) · approx. 8:45 AM UTC+5 local
On October 15, 2025 at 03:45 UTC, a magnitude 4.8 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -31.6731°, 76.4956°. This earthquake was detected by 41 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
