2026-06-18 16:48:45 UTC (17 min ago) · approx. 6:48 AM UTC-10 local
On June 18, 2026 at 16:48 UTC, a magnitude 3.4 shallow crustal earthquake struck 6 km SSW of Soldotna, Alaska, at a depth of 61.6 km and coordinates 60.4330°, -151.0860°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
