Earthquakes in Peru — October 2025
6 earthquakes were recorded in Peru during October 2025, an average of 0.2 per day.
6 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 31 km.
The month's largest event in Peru was a magnitude 4.7 earthquake near Uchiza, Peru on 21 October 2025 at 05:24 UTC. A magnitude 4.7 earthquake radiates roughly 169 tons of TNT equivalent in seismic energy.
That is below the Peru monthly average of 13 events over the period we cover — a comparatively quiet month, and down from the 16 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 6 in the magnitude 4 range.
Activity peaked on 21 October, when 2 events were recorded.
The month's largest events were M4.7 near Uchiza, Peru on 21 October at 10 km; M4.6 near Pacocha, Peru on 25 October at 36 km; M4.6 near San Juan, Peru on 07 October at 10 km.
That is 52% below the 13 events Peru averages per month across the 21 months on record.
