2024-03-18 23:11:41 UTC (2024-03-18) · approx. 3:11 PM UTC-8 local
On March 18, 2024 at 23:11 UTC, a magnitude 3.1 shallow crustal earthquake struck 28 km SE of Alamo, Nevada, at a depth of 9.5 km and coordinates 37.1766°, -114.9466°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
