Puerto Rico is made up of a number of islands.

Puerto Rico is an unincorporated territory of the United States (partially controlled by the US but not part of it) situated in the Caribbean Sea. Located in the Greater Antilles, Puerto Rico includes one main island as well as several other smaller islands such as Vieques, Mona, and Culebra. Puerto Rico has a population of approximately 3.4 million people, with San Juan as the capital and most populous city. The island is a popular tourist destination because of its rich culture, heritage, and natural beauty. The majority of Puerto Ricans are US citizens and enjoy free movement between the island and the mainland. However, since Puerto Rico is not a state, it does not have a vote in the US Congress.

Puerto Rico is located at the boundary of North America and Caribbean plates and is at risk of being deformed by the tectonic stress resulting from the interaction of the two plates. The tectonic stress may result in tsunamis and earthquakes. Approximately 71 miles north of Puerto Rico is the Puerto Rico Trench which is the deepest and largest trench in the Atlantic Ocean. It is located at the boundary between the two plates with Milwaukee Deep as the deepest point at 27,600 feet deep.
