2024-09-10 22:16:15 UTC (2024-09-10) · approx. 2:16 AM UTC+4 local
On September 10, 2024 at 22:16 UTC, a magnitude 4.0 shallow crustal earthquake struck 24 km WSW of Bojnūrd, Iran, at a depth of 10.0 km and coordinates 37.4258°, 57.0543°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
