B. rock slowly flows underground, like plastic. Seiches are like small tsunamis. Earthquake Zones. A nearby fault called the Sunda Megathrust, which runs under the Indian Ocean, caused one of the worst natural disasters in recent memory: a huge tsunami that struck the coasts of southern Asia in 2004, killing more than 280,000 people. It is a huge wave caused by an earthquake under the ocean. The plate boundary is a huge thrust fault called a megathrust. The 8.5 magnitude earthquake occurred at 19: 32 local The 1994 o A seismogram is a recording of the ground motion of an earthquake by a … Earthquakes along megathrusts are among the most damaging and deadly of all earthquakes. The last known megathrust earthquake in the northwest was in January, 1700, just over 300 years ago. An earthquake is shaking or trembling of the earth’s surface, caused by the seismic waves or earthquake waves that are generated due to a sudden movement (sudden release of energy) in the earth’s crust (shallow-focus earthquakes) or upper mantle (some shallow-focus and all intermediate and deep-focus earthquakes). Large earthquakes occur along the entire contact between the subducting plate and the overriding plate. Shearing within the prism causes slip and earthquakes along numerous thrust faults. This earthquake caused a surface displacement of the ocean floor on the order of ___ 10 m. Energy waves that are released during an earthquake are called ___ seismic waves. Recent examples include the magnitude 8.8 earthquake in Chile in February 2010 and the magnitude 9.1 earthquake offshore Sumatra in December 2004; the latter triggered a devastating tsunami. . A. rock bends elastically before breaking; the sudden break and/or frictional sliding causes earthquakes. Geological evidence indicates that such great earthquakes have occurred at least seven times in the last 3,500 years, a return interval of 400 to 600 years. Earthquakes are caused by the release of built-up pressure at plate boundaries. These earthquakes which are referred to as “Megathrust” earthquakes were 1952 Kamchatka, Russia, 1960 Chile (the world’s greatest so far with M … They can destroy buildings and infrastructure. The largest earthquakes on Earth occur at the interface between the two plates, called the megathrust. According to the elastic rebound theory of earthquake generation . Questions and Answers on Megathrust Earthquakes What is a megathrust earthquake? A megathrust earthquake is a very large earthquake that occurs in a subduction zone, a region where one of the earth's tectonic plates is thrust under another. The 1896 Sanriku earthquake was one of the most destructive seismic events in Japanese history. . Using this data scientists can deter what causes earthquakes in the region. ; A seismograph, or seismometer, is an instrument used … Tsunamis can also occur, with equally devastating and deadly effects. After it has flowed a certain distance, an earthquake occurs. Tsunamis can be tens of feet high when they hit the shore and can do enormous damage to the coastline. Tracking location of earthquakes Scientists began tracking and pinpointing the location of earthquakes using data from seismograms. The 2004 Sumatra earthquake and tsunami was caused by an earthquake along a ___ megathrust.
