M4.6 Earthquake 45 km SE of Ger?sh, Iran — October 14, 2020
2020-10-14 11:06:17 UTC (2020-10-14) · approx. 3:06 PM UTC+4 local
On October 14, 2020 at 11:06 UTC, a magnitude 4.6 shallow crustal earthquake struck 45 km SE of Ger?sh, Iran, at a depth of 10.0 km and coordinates 27.3738°, 54.4577°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
