Earthquakes in Puerto Rico — June 2026

157 earthquakes were recorded in Puerto Rico during June 2026, an average of 5.2 per day.

3 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 24 km.

The month's largest event in Puerto Rico was a magnitude 4.3 earthquake near Luquillo, Puerto Rico on 14 June 2026 at 05:24 UTC. A magnitude 4.3 earthquake radiates roughly 43 tons of TNT equivalent in seismic energy.

That is close to the Puerto Rico monthly average of 173 events over the period we cover, and down from the 173 recorded the previous month.

95% of events here are shallow (under 70 km), 5% 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 20 in the magnitude 1 range, 89 in the magnitude 2 range, 45 in the magnitude 3 range, 3 in the magnitude 4 range.

Activity peaked on 14 June, when 24 events were recorded.

The month's largest events were M4.3 near Luquillo, Puerto Rico on 14 June at 50 km; M4.3 near Luquillo, Puerto Rico on 11 June at 51 km; M4.0 near Culebra, Puerto Rico on 11 June at 8 km.

That is close to the 173 events Puerto Rico averages per month across the 21 months on record.
