Felt by 131 people across surrounding communities. Maximum shaking intensity MMI 6.6 (very strong).
On October 3, 2023 at 09:21 UTC, a magnitude 5.7 shallow crustal earthquake struck 39 km NE of Dipayal, Nepal, at a depth of 13.0 km and coordinates 29.4973°, 81.2420°. The earthquake was reported felt by 131 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.6 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 226 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 605, making it a moderate-impact event. The nearest populated place is Dipayal (population 23,416).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
