DOES PUERTO RICO HAVE A VOLCANO?
Yes....kind of. Puerto Rico was formed by a volcano but there are no active volcanos on the island. Puerto Rico lies on the boundary of the Caribbean and North American plates. When those plates shift, there is potential for earthquakes! The last major earthquake occurred on October 11, 1918 with a magnitude of 7.5 on the Richter scale! It began off the coast of Aguadilla and was followed by a tsunami.
