On April 23, 2022 at 21:22 UTC, a magnitude 5.3 shallow crustal earthquake struck 185 km W of Port McNeill, Canada, at a depth of 10.0 km and coordinates 50.4725°, -129.6895°. This earthquake was detected by 189 seismic stations with good location accuracy and was assigned a USGS significance rating of 435, placing it among routine seismic activity.
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.
