2023-04-18 22:15:59 UTC (2023-04-18) · approx. 3:15 PM UTC-7 local
On April 18, 2023 at 22:15 UTC, a magnitude 2.5 shallow crustal earthquake struck 21 km WSW of Carlsbad, New Mexico, at a depth of 5.0 km and coordinates 32.3745°, -104.4501°.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
