Andrei Gabrielov Purdue University West Lafayette IN USA wwwmathpurdueeduagabriel San Francisco April 18 1906 Plate Tectonics Major tectonic plates and world seismicity Plate Tectonics. By. : 10 grade. What is an earthquake ?. Simply, earthquakes are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. . -Black. Shensi, China. When did this happen?. January 23, 1556. How many people died?. It is estimated that 830,000 people where killed in it.. The geological effects that were reported where ground fissures, uplift, subsidence, liquefaction, and landslides.. :. What You Need To Know. Tsunami Outreach Oregon. Oregon Department of . Geology . and Mineral Industries . Cascadia Earthquake: Key Messages. A local Cascadia earthquake will probably happen in most people’s lifetime or their children’s lifetime.. 8.53. Write a narrative with supporting text describing the effects of the New Madrid Earthquakes of 1811-12 on the land and people of Tennessee. (G, H, . TN). Bell Ringer. : What might this map represent? Why do you think so? . Comparing and contrasting earthquakes. Have compared the impacts of earthquakes on a . MEDC. and a . LEDC. .. Have considered development as a key issue in . earthquake response. .. By the end of this section, you will: . Why do people live in tectonic areas and how are the possible effects being managed?. Why do people live in tectonic areas?. In pairs discuss: . Which area of the world has the highest number of people potentially affected by tectonic activity?. Why you need to prepare for the next earthquake . Alaska has more earthquakes than any other region of the U.S. . And in fact is one of the most seismically active area of the world.. Great earthquakes (Earthquakes larger than magnitude 8) rock the state on average every 13 years since the 1900. . Earthquake Risk. Earthquakes are likely wherever plate movement stores energy in the rock along faults.. Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occurred.. What are Destructive Forces?. A destructive force is a process that lowers or tears down the surface features of the Earth. . Examples of Destructive Forces:. Destructive forces can occur in many ways. The following are common examples of destructive forces:. earthquake. (also known as a . quake. , . tremor. or . temblor. ) is the result of a sudden release of energy in the . Earth's. . crust. that creates . seismic waves. . . The . seismicity. , . seismism. Move it, move it !!. What are they?. Fault: a break or fracture in the crust of Earth.. Earthquakes: shaking or trembling of the earth caused by movement along a fault.. Uplift: upward movement of Earth’s crust.. (Lesson 22). ENQUIRY QUESTION 3:. How successful is the . management. of tectonic hazards and disasters?. H/W :TASK 4. Read the information . (Hodder page 90 in this booklet) . about two recent tectonic mega disasters : . Earthquake is a shaking of the ground caused by the sudden breaking and shifting of large sections of Earth's rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. A severe earthquake may release energy 10,000 times as great as that of the first atomic bomb. Rock movements during an earthquake can make rivers change their course. Earthquakes can trigger landslides that cause great damage and loss of life. Large earthquakes beneath the ocean can create a series of huge, destructive waves called tsunamis that flood coasts for many miles. . An . earthquake. is a sudden motion or trembling of the Earth caused by the abrupt release of energy that is stored in rocks. . Modern . geologists know that most earthquakes occur along plate boundaries, where huge tectonic plates separate, converge, or slip past one another.
