2025-10-18 21:36:37 UTC (2025-10-18) · approx. 11:36 PM UTC+2 local
On October 18, 2025 at 21:36 UTC, a magnitude 4.5 shallow crustal earthquake struck 98 km NNE of Tobruk, Libya, at a depth of 10.0 km and coordinates 32.8796°, 24.4403°. This earthquake was detected by 21 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
