M3.9 Earthquake near off the coast of Oregon — July 12, 2024
2024-07-12 19:27:20 UTC (2024-07-12) · approx. 10:27 AM UTC-9 local
On July 12, 2024 at 19:27 UTC, a magnitude 3.9 shallow crustal earthquake struck near off the coast of Oregon, at a depth of 10.0 km and coordinates 44.4713°, -129.9801°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
