The month's largest event in Mexico was a magnitude 4.1 earthquake near Buenos Aires, Mexico on 01 October 2026 at 08:14 UTC. A magnitude 4.1 earthquake radiates roughly 21 tons of TNT equivalent in seismic energy.

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.
