On August 31, 2022 at 23:28 UTC, a magnitude 2.7 shallow crustal earthquake struck 15km ESE of Yosemite Valley, CA, at a depth of 16.3 km and coordinates 37.6675°, -119.4313°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 147 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 m — a useful intuition for the size of the slip patch on the fault.
