Earthquakes in Puerto Rico — February 2025

149 earthquakes were recorded in Puerto Rico during February 2025, an average of 5.3 per day.

0 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 21 km.

The month's largest event in Puerto Rico was a magnitude 4.0 earthquake near Suárez, Puerto Rico on 24 February 2025 at 00:15 UTC. A magnitude 4.0 earthquake radiates roughly 13 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 160 recorded the previous month.

96% of events here are shallow (under 70 km), 4% 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 5 in the magnitude 1 range, 107 in the magnitude 2 range, 37 in the magnitude 3 range.

Activity peaked on 01 February, when 9 events were recorded.

The month's largest events were M4.0 near Suárez, Puerto Rico on 24 February at 28 km; M3.8 near Tierras Nuevas Poniente, Puerto Rico on 21 February at 35 km; M3.8 near Aguadilla, Puerto Rico on 25 February at 9 km.

That is 14% below the 173 events Puerto Rico averages per month across the 21 months on record.
