M4.6 Earthquake 52 km NNW of Barishal, Pakistan — August 23, 2026
2026-08-23 10:04:42 UTC (1 hour ago) · approx. 3:04 PM UTC+5 local
Aftershock of the M5.1 mainshock.
On August 23, 2026 at 10:04 UTC, a magnitude 4.6 shallow crustal earthquake struck 52 km NNW of Barishal, Pakistan, at a depth of 45.5 km and coordinates 36.7596°, 74.4767°. This earthquake was detected by 79 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.1 mainshock that occurred 10 days ago 59 km NNW of Barishal, Pakistan. 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 4.6 earthquake near Barishal, Pakistan?
The magnitude 4.6 earthquake that struck 52 km NNW of Barishal, Pakistan on August 23, 2026 at 10:04 UTC had a depth of 45.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 36.7596°, 74.4767°, which is 52 km NNW of Barishal, Pakistan.
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.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.6 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 59 km NNW of Barishal, Pakistan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
