2024-03-23 20:09:35 UTC (2024-03-23) · approx. 9:09 AM UTC-11 local
On March 23, 2024 at 20:09 UTC, a magnitude 3.2 intermediate depth earthquake struck 52 km WSW of Unalaska, Alaska, at a depth of 106.7 km and coordinates 53.7216°, -167.2849°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
