M4.8 Earthquake near Mid-Indian Ridge — March 18, 2026
2026-03-18 14:51:06 UTC (2026-03-18) · approx. 7:51 PM UTC+5 local
On March 18, 2026 at 14:51 UTC, a magnitude 4.8 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -21.5849°, 68.8673°. This earthquake was detected by 68 seismic stations with excellent 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.
