2022-06-21 21:50:24 UTC (2022-06-21) · approx. 2:50 AM UTC+5 local
On June 21, 2022 at 21:50 UTC, a magnitude 4.5 shallow crustal earthquake struck 52 km W of Miran Shah, Pakistan, at a depth of 10.0 km and coordinates 32.9999°, 69.5099°. This earthquake was detected by 91 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
