On April 18, 2021 at 22:17 UTC, a magnitude 4.7 shallow crustal earthquake struck 19 km NE of Bandar-e Gen?veh, Iran, at a depth of 10.0 km and coordinates 29.7143°, 50.6416°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Iran, a region characterized by the Zagros fold-and-thrust belt, where the Arabian Plate collides with Eurasia at 20-25 mm per year. The nearest mapped fault system is the Zagros Fault. View all earthquakes in Iran.
