This article was most recently revised and updated by The northern boundary of Puerto Rico is marked by the 800-kilometer-long Puerto Rico Trench, which is the deepest part of the Atlantic Ocean, with a maximum depth of 8,648 meters (Figure 1). The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains. Geology of Puerto Rico An Overview of the Plate Tectonic Origin of the Caribbean ... Island Arc formation at a Subduction Zone.
The Earth’s crust is broken up into a series of massive sections called plates. The Atlantic Ocean began its formation around 150 million years ago, during the Jurassic time, after the separation of Africa and South America. The risk of a major quake, underwater landslide and mega tsunami are as great as that of the Seattle area. The Puerto Rico Trench is about 1,090 miles (1,750 km) long and 60 miles (100 km) wide.

The ocean’s name, derived from Greek mythology, means the “Sea of Atlas.” It is second in size… The Puerto Rico Trench is unique because its formation is not only due to the transform boundary but also in combination with a subduction zone.
Tectonics 263, 7–33. This subduction zone is responsible for the volcanism of the West Indies to the southeast of Puerto Rico.

National Geographic HeadquartersNational Geographic Society is a 501 (c)(3) organization. At this trench the North American plate is being subducted by the Caribbean plate. The Puerto Rico trench is at a complex transition from the subduction boundary to the south and the transform boundary to the west. The Puerto Rico Trench is the deepest part of the Atlantic Ocean.Students read about the establishment of the Mariana Trench Marine National Monument and discuss why it is important to preserve the Mariana Trench and surrounding area. The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. This results in the formation of the deep Puerto Rico Trench and a zone of intermediate focus earthquakes (70-300 km depth) within the subducted slab.

These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains. A mud volcano was discovered at a depth of 7,900 meters (25,919 feet).
