On June 21, 2020 at 22:40 UTC, a magnitude 5.6 shallow crustal earthquake struck 22 km E of North Vanlaiphai, India, at a depth of 10.8 km and coordinates 23.1449°, 93.2856°. The earthquake was reported felt by 52 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.5 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is North Vanlaiphai (population 3,475).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 km — a useful intuition for the size of the slip patch on the fault.
