How were Puerto Rico trenches formed?
The Trench began to form about 70 million years ago, as the North American and Caribbean tectonic plates started to grind past each other along the Bunce Fault system named for a pioneering geophysicist, Dr. Elizabeth Bunce. This fault system is similar to the San Andreas Fault in California.
Can Puerto Rico be underwater?
Sea level has risen by about four inches relative to Puerto Rico’s shoreline since 1960. As the oceans and atmosphere continue to warm, sea level around Puerto Rico is likely to rise one to three feet in the next century.

To the north part of the island, the North America plate is moving past and sinking below Puerto Rico, while in the southern region, the Caribbean plate is sinking into the mantel underneath the island. “Essentially, the island is being squeezed between these two tectonic plates,” he said.
What are the 5 deepest trenches on Earth?
The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.
Is there anywhere deeper than the Mariana Trench?
After all, it was only in 1997 that researchers discovered the Sirena Deep, which is also located in the Mariana Trench, which they measured at 35,210 feet, less than a thousand feet shallower than the Challenger Deep.
How old is the Puerto Rican trench?
The origin of the trench can be traced back to the beginning of the Cenozoic Era (about 65 million years ago). The Puerto Rico Trench appears to be part of a complex system of sinistral strike-slip faults in the north Caribbean; the trench seems to have been open continuously for about 70 million years.
Is Puerto Rico in danger of a tsunami?
Puerto Rico Seismic Network. The danger of a tsunami in Puerto Rico is real. Since 1867, two tsunamis have affected their coastal region, causing death and destruction in 1867 and 1918.
Can Puerto Rico get a tsunami?
Large tsunamis have also hit Puerto Rico and Hispaniola, reportedly killing 1800 people in 1946 and 40 people in 1918. Images of the slope north of Puerto Rico disclose massive slope failure scars, as much as 50 km across, that probably generated tsunamis along the north shore of the island.
What is the depth of the Puerto Rico Trench?
The Puerto Rico Trench is about 1,090 miles (1,750 km) long and 60 miles (100 km) wide. The deepest point in the Atlantic Ocean, the Milwaukee Depth , lies at a depth of 27,493 feet (8,380 m) in the western end of the trench, about 100 miles (160 km) northwest of Puerto Rico.
What do you need to know about trenching and shoring?
Trenching and Shoring. Shoring uses a system of wall sheets, wales and cross braces created by an engineer to hold up and stabilize the trench walls. Trench boxes can also be used to hold up walls. Trench boxes can be stacked for deep trenches, but they cannot be used to raise the height of the trench wall.
Who was the first person to dive into the Puerto Rico Trench?

Is the Puerto Rico Trench a hazard to Puerto Rico?
Despite its fascinating and mysterious origin and the potential hazard it poses to Puerto Rico and the Virgin Islands, the Puerto Rico Trench has not undergone much study during the past 25 years. Our technical capabilities to explore the oceans have improved tremendously during that period.
