The Puerto Rico Trench is a deep underwater valley located north of the island of Puerto Rico. It is the deepest part of the Atlantic Ocean, reaching depths of about 8,376 meters (27,480 feet). The trench is formed by the interaction of the North American and Caribbean tectonic plates, making it a significant geological feature. This trench plays a crucial role in the study of earthquakes and tsunamis in the region. The tectonic activity in the area can lead to seismic events, impacting nearby islands and coastal areas. Understanding the Puerto Rico Trench helps scientists assess geological hazards and improve safety measures for local communities.
