On April 26, 2026 at 02:24 UTC, a magnitude 4.2 shallow crustal earthquake struck 5 km NW of Walenstadt, Switzerland, at a depth of 5.0 km and coordinates 47.1585°, 9.2589°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
