M4.6 Earthquake in the Afghanistan-Tajikistan-Pakistan region — August 4, 2022
2022-08-04 19:08:10 UTC (2022-08-04) · approx. 12:08 AM UTC+5 local
On August 4, 2022 at 19:08 UTC, a magnitude 4.6 intermediate depth earthquake struck in the Afghanistan-Tajikistan-Pakistan region, at a depth of 98.9 km and coordinates 36.4812°, 71.3235°. This earthquake was detected by 157 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
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 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 earthquakes can continue for several days and gradually diminish over time.
Has Afghanistan had earthquakes this big before?
The largest recorded earthquake in Afghanistan was the M7.5 Hindu Kush earthquake of October 26, 2015. Today's magnitude 4.6 event is significantly smaller than that historical record.
