M6.3 Earthquake 25 km NNE of Zindah Jān, Afghanistan — October 7, 2023
2023-10-07 07:12:49 UTC (2023-10-07) · approx. 11:12 AM UTC+4 local
Felt by 11 people across nearby locations. Maximum shaking intensity MMI 7.9 (severe).
On October 7, 2023 at 07:12 UTC, a magnitude 6.3 shallow crustal earthquake struck 25 km NNE of Zindah Jān, Afghanistan, at a depth of 8.0 km and coordinates 34.5442°, 61.8891°. The earthquake was reported felt by 11 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.9 (severe). The USGS PAGER system issued a orange alert level for this event, indicating regional impact possible. This earthquake was detected by 244 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1010, making it one of the most significant global earthquakes in recent days. The nearest populated place is Zindah Jan (population 10,104).
Physical scale: An earthquake of magnitude 6.3 releases seismic energy equivalent to roughly 43 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 13 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.3 earthquakes can continue for weeks to months 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 6.3 event is significantly smaller than that historical record.
