M3.0 Earthquake 6km NNW of Delta, B.C., MX — September 8, 2021
2021-09-08 21:17:52 UTC (2021-09-08) · approx. 1:17 PM UTC-8 local
On September 8, 2021 at 21:17 UTC, a magnitude 3.0 shallow crustal earthquake struck 6km NNW of Delta, B.C., MX, at a depth of 16.6 km and coordinates 32.4087°, -115.2058°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 494 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 72 m — a useful intuition for the size of the slip patch on the fault.
