The 2004 quake ruptured a 900-mile stretch along the Indian and Australian plates 31 miles below the ocean floor. According to the Global Historical Tsunami Database, since 1900, over 80% of likely tsunamis were generated by earthquakes. Students can investigate tsunamis to discover the impacts of Earth's systems on humans. This would make the Cascadia subduction zoneunlikemost other subduction zones around the world. Two examples of stochastic slip distributions are shown here (warm colors represent high amounts of slip). Because the orientation of the greatest horizontal principal stress throughout the Pacific Northwest differs considerably from the direction of convergence between the Juan de Fuca and North American plates, the relationship between, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), Some Native American tribal nations in the Pacific Northwest havelegends, USGS Professional Paper 1661-B, Geist, E.

The wave also caused destruction on the mainland, flooding and damaging parts of the state of Washington and Oregon. The result is the generation of secondary tsunamis that initially travel in a different direction than the deep-ocean and local tsunamis shown in the rupture diagrams above. The Portland Hills quake could destroy one in three buildings in the Portland metro region, displace as many as 257,000 people and injure 63,000. As a tsunami enters shallow water near coastal shorelines, it slows offsite link to 20 to 30 mph. A "SM," or small tsunami, simulates what would happen in an 8.7 magnitude A lock ( The wave also caused destruction on the mainland, flooding and damaging parts of the state of Washington and Oregon. To determine therangeof possible tsunami amplitudes for a given earthquake magnitude and location, a Monte Carlo-type simulation can be run, involving a large number of slip distributions.

However, while there is no indication it could happen soon (but could), there are scientifically sound reasons for concern that at some point a mega-tsunami could engulf the entire East Coast with a wave almost 200 feet high sweeping everything and everybody up to 20 milesinland. Privacy Policy. A .gov website belongs to an official government organization in the United States. the potential for a 9.0+ magnitude earthquake caused by the Cascadia Subduction The obliquity of the slip vector (D) in the fault plane of dip () is measured by the angle () that the slip vector makes with a horizontal line in the fault plane. Meanwhile, by allowing police stations and firehouses to be built within the inundation zone, Oregon is directly endangering the people tasked with showing up when disaster strikes. The left part of the figure shows the portion of a fault that ruptures in green. Indeed, some observers suspect that the law was largely designed to discredit and further defang the already underfunded DOGAMI, the state entity that has done the lions share of work in mapping the tsunami-inundation zone and trying to keep critical infrastructure and vulnerable citizens out of it. In addition, many schools, homes, and businesses are located in tsunami hazard zones offsite link.
