M6.0 Earthquake in the Nicobar Islands, India region — March 12, 2025
2025-03-12 05:42:11 UTC (2025-03-12) · approx. 11:42 AM UTC+6 local
On March 12, 2025 at 05:42 UTC, a magnitude 6.0 shallow crustal earthquake struck in the Nicobar Islands, India region, at a depth of 23.0 km and coordinates 6.9701°, 92.5548°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 139 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 554, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 km — a useful intuition for the size of the slip patch on the fault.
ShakeMap — predicted shaking intensity
Modeled ground-motion intensity contoured on the Modified Mercalli scale (MMI). Computed by the USGS from the moment-tensor solution and regional ground-motion prediction equations.

Population exposure (USGS PAGER)
Estimated population that experienced each level of shaking. Based on the USGS PAGER rapid impact assessment, which combines ShakeMap output with global population grids.
| Shaking intensity (MMI) | Description | Population exposed |
|---|---|---|
| MMI 3 | weak | 18,899 |
| MMI 4 | light | 6,953 |
