2023-04-02 21:08:54 UTC (2023-04-02) · approx. 4:08 PM UTC-5 local
On April 2, 2023 at 21:08 UTC, a magnitude 3.7 shallow crustal earthquake struck 33 km E of Miches, Dominican Republic, at a depth of 56.0 km and coordinates 18.9806°, -68.7295°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
