M2.4 Earthquake 5 km ENE of Houston, Alaska — July 27, 2025
2025-07-27 17:28:29 UTC (2025-07-27) · approx. 7:28 AM UTC-10 local
On July 27, 2025 at 17:28 UTC, a magnitude 2.4 shallow crustal earthquake struck 5 km ENE of Houston, Alaska, at a depth of 46.9 km and coordinates 61.6504°, -149.7307°.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
