Earthquakes in Peru — March 2025

18 earthquakes were recorded in Peru during March 2025, an average of 0.6 per day.

18 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 142 km.

The month's largest event in Peru was a magnitude 5.6 earthquake near Iñapari, Peru on 11 March 2025 at 14:08 UTC. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

That is well above the Peru monthly average of 13 events over the period we cover — an unusually active month, and up from the 17 recorded the previous month.

17% of events here are shallow (under 70 km), 78% intermediate (70–300 km) and 6% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 16 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 31 March, when 2 events were recorded.

The month's largest events were M5.6 near Iñapari, Peru on 11 March at 641 km; M5.4 near Cayarani, Peru on 07 March at 107 km; M4.8 near Circa, Peru on 14 March at 83 km.

That is 42% above the 13 events Peru averages per month across the 21 months on record.
