M3.0 Earthquake 69 km ENE of Chase, Alaska — May 11, 2025
2025-05-11 17:50:41 UTC (2025-05-11) · approx. 7:50 AM UTC-10 local
On May 11, 2025 at 17:50 UTC, a magnitude 3.0 shallow crustal earthquake struck 69 km ENE of Chase, Alaska, at a depth of 51.0 km and coordinates 62.6411°, -148.8156°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
