2023-11-17 01:37:11 UTC (2023-11-17) · approx. 8:37 AM UTC+7 local
Felt by 69 people across nearby locations. Maximum shaking intensity MMI 7.2 (severe).
On November 17, 2023 at 01:37 UTC, a magnitude 5.7 shallow crustal earthquake struck 76 km SW of Kēng Tung, Myanmar, at a depth of 15.7 km and coordinates 21.2170°, 99.3304°. The earthquake was reported felt by 69 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.2 (severe). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 117 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 551, placing it among routine seismic activity. The nearest populated place is Chiang Saen (population 10,807).
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.
