2022-11-30 00:55:55 UTC (2022-11-30) · approx. 4:55 PM UTC-8 local
Felt by 315 people across surrounding communities. Maximum shaking intensity MMI 7.6 (severe).
On November 30, 2022 at 00:55 UTC, a magnitude 5.3 shallow crustal earthquake struck 45 km ESE of Peace River, Canada, at a depth of 4.0 km and coordinates 56.1593°, -116.5760°. The earthquake was reported felt by 315 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.6 (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 124 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 621, making it a moderate-impact event. The nearest populated place is Peace River (population 5,340).
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
