M4.9 Earthquake 46 km NNE of Kanysh-Kyya, Kyrgyzstan — October 5, 2025
2025-10-05 20:28:59 UTC (2025-10-05) · approx. 1:28 AM UTC+5 local
Felt by 29 people across nearby locations. Maximum shaking intensity MMI 6.4 (very strong).
On October 5, 2025 at 20:28 UTC, a magnitude 4.9 shallow crustal earthquake struck 46 km NNE of Kanysh-Kyya, Kyrgyzstan, at a depth of 10.0 km and coordinates 42.1582°, 71.2883°. The earthquake was reported felt by 29 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.4 (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 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 380, placing it among routine seismic activity. The nearest populated place is Kanysh-Kyya (population 0).
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
