On February 4, 2023 at 12:23 UTC, a magnitude 4.7 shallow crustal earthquake struck 63 km NNE of Khand?d, Afghanistan, at a depth of 59.0 km and coordinates 37.4442°, 72.6877°. This earthquake was detected by 58 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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 4.7 earthquakes can continue for several days 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 4.7 event is significantly smaller than that historical record.
