No, there are no active volcanoes in Puerto Rico. While Puerto Rico is located in a region with volcanic activity, the island itself was formed from the movement of tectonic plates and does not have any active volcanic vents.

However, there is evidence of ancient volcanic activity in the area. Some geological formations on the island, like the "Cerro La Santa" in the municipality of Jayuya, are thought to be remnants of extinct volcanoes.
