2024-10-08 19:00:59 UTC (2024-10-08) · approx. 11:00 AM UTC-8 local
On October 8, 2024 at 19:00 UTC, a magnitude 2.3 shallow crustal earthquake struck 16 km ESE of Yosemite Valley, CA, at a depth of 14.7 km and coordinates 37.7135°, -119.3940°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 47.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 24 m — a useful intuition for the size of the slip patch on the fault.
