M3.2 Earthquake 7km NW of Delta, B.C., MX — October 18, 2020
2020-10-18 19:04:16 UTC (2020-10-18) · approx. 11:04 AM UTC-8 local
On October 18, 2020 at 19:04 UTC, a magnitude 3.2 shallow crustal earthquake struck 7km NW of Delta, B.C., MX, at a depth of 7.4 km and coordinates 32.3963°, -115.2507°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 1.1 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 104 m — a useful intuition for the size of the slip patch on the fault.
