puerto rico trench tsunami

Trenches in the Pacific are located in places where one tectonic plate subducts or slides under another one. "But tsunamis have the potential of killing so many people if we do not respond appropriately.". The National Center for Tsunami Research, which is part of the Pacific Marine Environmental Laboratory, spearheaded the research efforts in the United States. 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. Figure 4. The earthquake measured 7.1 on the moment magnitude scale and IX on the Mercalli intensity scale. Eyewitness reports of an 1867 Virgin Islands tsunami gave a maximum wave height of >7 m in … Puerto Rico Trench can be dangerous and the cause of future disasters. "But now some think that several faults in the region could be capable of producing earthquakes of 8.6, and the catastrophic planning by our emergency management community is considering 8.5 and 9.0 earthquakes," she noted. Surveys of the trench have shown that the tectonic plate, just north of the Puerto Rico Trench is shifting. The Puerto Rico trench exhibits great water depth, extremely low gravity anomaly, and a tilted carbonate platform between (reconstructed) elevations of +1300 m and -4000 m. we suggest that these features are manifestations of large vertical movements of a segment of the Puerto Rico Trench, its forearc, and the island of Puerto Rico that took place 3.3 m.y. https://www.sciencephoto.com/.../puerto-rico-trench-tsunami-simulation Caribbean region and from a submarine landslide in the Puerto Rico Trench. Medical research advances and health news, The latest engineering, electronics and technology advances, The most comprehensive sci-tech news coverage on the web. 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. Click image for larger view and image credit. The geography of Puerto Rico consists of an archipelago located between the Caribbean Sea and the North Atlantic Ocean, east of the Dominican Republic, west of the Virgin Islands and north of Venezuela. The risk of a major quake, underwater landslide and mega tsunami are as great as that of the Seattle area. Its northward edge is at a depth of 4,200 m, and its southern edge can be found on land in Puerto Rico at an elevation of a few hundred meters. It is moving downwards almost underneath Puerto Rico and shows signs of recent movement. These deep areas are basically timebombs for earthquakes, as landslides in these deep zones can create devastating tsunamis. National Oceanic and Atmospheric Administration.

Neither your address nor the recipient's address will be used for any other purpose. The first wave may not be the largest nor the most destructive. The region has high seismicity and large earthquakes (figure 2). An 8.1 earthquake occurred in the Puerto Rico trench in the 1700s and two 7.5 earthquakes occurred near the Mona Passage last century — including the 1918 earthquake that generated a … This trench is capable of producing 8.0 earthquakes and above. This document is subject to copyright. Its depth is comparable to the deep trenches in the Pacific Ocean. Numerical simulation of the 1918 Puerto Rico tsunami showing calculated inundation of the Aguadilla coast in northwest Puerto Rico. Bathymetry of the northeast corner of the Caribbean plate. After the devastation of the Indian Ocean Tsunami on December 26, 2004, much attention has been given to tsunami research. 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. There are few land areas or islands to block a tsunami generated near the Puerto Rico Trench from entering the Atlantic Ocean.
