2024-06-18 19:01:15 UTC (2024-06-18) · approx. 9:01 AM UTC-10 local
On June 18, 2024 at 19:01 UTC, a magnitude 2.1 shallow crustal earthquake struck 6 km SSW of Salcha, Alaska, at a depth of 10.8 km and coordinates 64.4741°, -146.9627°.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
