2026-10-11 17:08:25 UTC (2026-10-11) · approx. 7:08 PM UTC+2 local
On October 11, 2026 at 17:08 UTC, a magnitude 4.5 shallow crustal earthquake struck 17 km E of Mtinko, Tanzania, at a depth of 10.0 km and coordinates -4.5620°, 35.0117°. This earthquake was detected by 14 seismic stations with good 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.
