The month's largest event in Bolivia was a magnitude 4.5 earthquake near Colchani, Bolivia on 06 October 2026 at 06:54 UTC. A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.
That is below the Bolivia monthly average of 3 events over the period we cover — a comparatively quiet month, and down from the 2 recorded the previous month.
0% of events here are shallow (under 70 km), 100% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.
