On September 29, 2022 at 22:22 UTC, a magnitude 5.6 intermediate depth earthquake struck 78 km SE of Mawlaik, Myanmar, at a depth of 150.0 km and coordinates 23.1002°, 94.8968°. The earthquake was reported felt by 21 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.9 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 161 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 491, placing it among routine seismic activity. The nearest populated place is Mawlaik (population 44,540).

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.
