M4.3 Earthquake in the Afghanistan-Tajikistan-Pakistan region — September 19, 2022
2022-09-19 22:36:13 UTC (2022-09-19) · approx. 3:36 AM UTC+5 local
On September 19, 2022 at 22:36 UTC, a magnitude 4.3 intermediate depth earthquake struck in the Afghanistan-Tajikistan-Pakistan region, at a depth of 207.4 km and coordinates 36.4285°, 71.1730°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 5.2 mainshock that occurred 21 days ago 52 km SSW of Jurm, Afghanistan. Since the mainshock, the USGS has recorded 0 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 4.3 earthquake in the Afghanistan-Tajikistan-Pakistan region?
The magnitude 4.3 earthquake that struck in the Afghanistan-Tajikistan-Pakistan region on September 19, 2022 at 22:36 UTC had a depth of 207.4 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 4.3 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 52 km SSW of Jurm, Afghanistan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
