M4.9 Earthquake 21 km ENE of Nahr?n, Afghanistan — December 22, 2020
2020-12-22 01:01:33 UTC (2020-12-22) · approx. 6:01 AM UTC+5 local
On December 22, 2020 at 01:01 UTC, a magnitude 4.9 shallow crustal earthquake struck 21 km ENE of Nahr?n, Afghanistan, at a depth of 26.1 km and coordinates 36.1322°, 69.3533°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
