Earthquakes in Chile — October 2026
1 earthquakes were recorded in Chile during October 2026, an average of 0.0 per day.
1 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 32 km.
The month's largest event in Chile was a magnitude 4.3 earthquake near Valparaíso, Chile on 02 October 2026 at 17:28 UTC. A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.
That is below the Chile monthly average of 32 events over the period we cover — a comparatively quiet month, and down from the 35 recorded the previous month.
100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.
By band, the catalogue holds 1 in the magnitude 4 range.
That is 97% below the 32 events Chile averages per month across the 23 months on record.
