M4.0 Earthquake 106 km SSW of Nikolski, Alaska — May 2, 2024
2024-05-02 20:23:26 UTC (2024-05-02) · approx. 9:23 AM UTC-11 local
On May 2, 2024 at 20:23 UTC, a magnitude 4.0 shallow crustal earthquake struck 106 km SSW of Nikolski, Alaska, at a depth of 10.0 km and coordinates 52.0307°, -169.3591°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
