M4.4 Earthquake 30 km S of Jurm, Afghanistan — October 27, 2023
2023-10-27 19:13:34 UTC (2023-10-27) · approx. 12:13 AM UTC+5 local
On October 27, 2023 at 19:13 UTC, a magnitude 4.4 intermediate depth earthquake struck 30 km S of Jurm, Afghanistan, at a depth of 211.8 km and coordinates 36.5947°, 70.8742°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 5.3 mainshock that occurred 4 days ago 35 km SSW 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 4.4 earthquake near Jurm, Afghanistan?
The magnitude 4.4 earthquake that struck 30 km S of Jurm, Afghanistan on October 27, 2023 at 19:13 UTC had a depth of 211.8 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 35 km SSW of Jurm, Afghanistan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
