M3.9 Earthquake 25 km WSW of Ashkāsham, Afghanistan — March 27, 2026
2026-03-27 18:25:44 UTC (2026-03-27) · approx. 11:25 PM UTC+5 local
On March 27, 2026 at 18:25 UTC, a magnitude 3.9 intermediate depth earthquake struck 25 km WSW of Ashkāsham, Afghanistan, at a depth of 104.1 km and coordinates 36.6003°, 71.2723°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.4 mainshock that occurred 25 days ago 38 km S of Jurm, Afghanistan. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 3.9 earthquake near Ashkāsham, Afghanistan?
The magnitude 3.9 earthquake that struck 25 km WSW of Ashkāsham, Afghanistan on March 27, 2026 at 18:25 UTC had a depth of 104.1 km. For context, this was a minor earthquake typically detected only by instruments.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.4 one earlier?
No. This magnitude 3.9 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 38 km S of Jurm, Afghanistan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
