The month's largest event in Costa Rica was a magnitude 5.1 earthquake near Sardinal, Costa Rica on 10 June 2026 at 03:01 UTC. A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.
That is below the Costa Rica monthly average of 3 events over the period we cover — a comparatively quiet month, and down from the 8 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, 1 in the magnitude 5 range.
The month's largest events were M5.1 near Sardinal, Costa Rica on 10 June at 65 km; M4.7 near Puerto Cortés, Costa Rica on 04 June at 10 km.
That is 31% below the 3 events Costa Rica averages per month across the 20 months on record.
