Felt by 5 people across nearby locations.
On October 28, 2023 at 19:27 UTC, a magnitude 5.0 shallow crustal earthquake struck 23 km NNW of Herāt, Afghanistan, at a depth of 10.0 km and coordinates 34.5493°, 62.1142°. This earthquake was detected by 160 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 388, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Afghanistan, a region characterized by the Hindu Kush deep seismic zone, where remnant subducted lithosphere produces intermediate-depth earthquakes at 150-300 km. View all earthquakes in Afghanistan.
