2024-07-03 20:21:42 UTC (2024-07-03) · approx. 11:21 AM UTC-9 local
On July 3, 2024 at 20:21 UTC, a magnitude 4.3 shallow crustal earthquake struck 215 km WSW of Tofino, Canada, at a depth of 10.0 km and coordinates 48.5794°, -128.7066°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
