An magnitude 2.5 earthquake occurred 7 km SSE of Maria Antonia, Puerto Rico on Sep 18, 2026 at 04:03 UTC. The epicenter was at a depth of 6 km — a shallow earthquake. Shallow quakes concentrate their energy near the surface, so they tend to produce stronger shaking close to the epicenter.

What this magnitude typically means
Very small earthquakes are usually only detected by instruments and are rarely felt. They are a normal part of background seismic activity. Tremor does not compute a single local shaking figure here, because how strong a quake feels at any address depends on distance, depth and local geology — open the interactive globe to explore the ShakeMap and estimated intensity.
