2021-06-30 20:24:23 UTC (2021-06-30) · approx. 2:24 PM UTC-6 local
On June 30, 2021 at 20:24 UTC, a magnitude 2.7 shallow crustal earthquake struck 4 km E of Rembrandt, Iowa, at a depth of 10.0 km and coordinates 42.8255°, -95.1057°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
