2025-03-11 19:37:12 UTC (2025-03-11) · approx. 9:37 AM UTC-10 local
On March 11, 2025 at 19:37 UTC, a magnitude 3.3 intermediate depth earthquake struck 58 km ENE of Pedro Bay, Alaska, at a depth of 134.3 km and coordinates 60.0373°, -153.1794°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
