The Orphan Tsunami of 1700, now in its second edition, tells this scientific detective story through its North American and Japanese clues. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk. The trench is less deep where the component of subduction is larger. Historically, other large earthquakes have also struck the area, such as one in 1787 (magnitude~8.1), possibly in the Puerto Rico Trench, and one in 1867 (magnitude~7.5) in the Anegada Trough (figure 1). While the most infamous subduction zones are found around the Pacific Ring of Fire — such as the one that set off the massive 2011 Japan tsunami — there is indeed a subduction zone capable of creating tsunamis near the East Coast. This two-volume set explores disasters that occurred around the world.

The North American plate is sliding under the Caribbean plate there, creating the . Puerto Rico, the Virgin Islands to its east, and eastern Hispaniola to its west, are located on an active plate boundary zone between the North American plate and the northeast corner of the Caribbean plate (figure 1). The Puerto Rico Trench is about 900 kilometers (560 miles) long and 100 kilometers (60 miles) wide, and it runs roughly parallel to the northern coast of Puerto Rico, about 75 miles offshore. The Puerto Rico Trench, the deepest part of the Atlantic Ocean, is located where the North American (NOAM) plate is subducting under the Caribbean plate (Figure 1). Found inside – Page iThis volume contains a collection of contributions that were presented in June 2007 in Montpellier (France) during a conference that gave a state of the art panorama and discussed the perspectives about "Subduction Zone Geodynamics". By determining the likely hazards and their causative mechanisms and providing this information to government agencies and the public, the USGS can aid in such activities as improvement of building codes, encouraging safer zoning, and assisting public education for response to hazards. An earthquake in these regions can cause one plate to subduct under another and displace huge amounts of water.

Other Puerto Rican cities also have substantial risk.The hazard from tsunamis is also apparent. Revised December 04, 2006 by the NOAA Ocean Explorer Webmaster Heavy black line = coast line; thin lines = topographic contours. The geologic settings of Puerto Rico and the Virgin Islands have created or contributed to several pressing societal issues related to human safety, environmental health, and economic development. There's the Puerto Rico Trench, which is the deepest part of the Atlantic Ocean and the 8th deepest trench in the world. To the north the trench is flanked by normal faults on the outer rise of unknown earthquake and tsunami potential (ten Brink et al., 2004), while to the south a subma-rine slide probably contributed to a 1918 tsunami in western Puerto Rico (López-Venegas, 2008). The tectonic profile of the Puerto Rico Trench subduction zone is sometimes compared to that of the Sumatra subduction zone, the site of the earthquake that triggered the devastating Indian Ocean tsunami of December 2004 killing some 250,000 people. However, most of the recorded tsunamis in the region were produced by Cluster of earthquakes around Puerto Rico and neighboring islands in December 2015. . In contrast, on its eastern boundary, the Caribbean overrides the North American plate, creating the island arc of the Lesser Antilles with its active volcanoes. The rate at which these plates come together is similar to the rate at which a human fingernail grows. The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean.The oceanic trench, the deepest in the Atlantic, is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trough to the coast of Central . Uri ten Brink, Chief Scientist The locations of the tremors at the plate interface may have profound implications about the capability of the Puerto Rico Trench subduction zone to generate large earthquakes and following tsunami. The Puerto Rico Trench is the purple area to the right (north) of the US territory, the Muertos Trough lies south of it. The Puerto Rico Trench, in contrast, is located at a boundary between two plates that slide past each other with only a small component of subduction. In a quote, Chief Research Officer at RMS Dr. Robert Muir-Wood said that while the Puerto Rico Trench, among others, is dormant, RMS analyses revealed that they were capable of generating tsunami waves similar in scale to those produced along the Japan Trench in 2011, bringing with them unprecedented devastation. The bathymetry of the ocean floor can focus wave energy and steer waves. Puerto Rico Trench Helps Assess Earthquake and Tsunami Hazards PAGES 349,354 The Puerto Rico Trench, the deepest part of the Atlantic Ocean, is located where the North American (NOAM) plate is subducting under the Caribbean plate (Figure l).The trench region may pose significant seismic and tsunami haz­ ards to Puerto Rico and the U.S.Virgin .
