2025-08-28 22:06:49 UTC (2025-08-28) · approx. 2:06 PM UTC-8 local
On August 28, 2025 at 22:06 UTC, a magnitude 2.1 shallow crustal earthquake struck 42 km SSW of Ucluelet, Canada, at a depth of 39.7 km and coordinates 48.5827°, -125.7295°.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 24.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 m — a useful intuition for the size of the slip patch on the fault.
