PPT-Section 19.3 – Measuring and Locating Earthquakes

8 th Grade Earth and Space Science Class Notes Earthquake Magnitude and Intensity Richter scale measures the magnitude energy of an earthquake Determined by the amplitude height of the seismic wave. 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.. 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. . The Earths crust . The earths crust is in constant motion.. Volcanoes and earthquakes arise as sections of crust push . toghether. or pulled apart. Volcanoes and earthquakes are more common in certain parts of the world. By monitoring ground vibrations scientists can sometimes. They Shape Our Landscape. As plates move, we may feel these movements as earthquakes. If there were no plate motions, our planet would not look like home. There would be no mountains, no valleys, no plateaus . other non-linear motions. M. . A. Floyd. Massachusetts Institute of Technology, Cambridge, MA, USA. School of Earth . Sciences, University of Bristol. United Kingdom. 2–5 May 2017. Material from T. A. Herring, R. W. King, M. A. Floyd (MIT) and S. C. . Earthquakes result from sudden motions along breaks in Earth’s crust and can affect landforms and societies.. An entire branch of Earth science, called . seismology. , is devoted to studying earthquakes.. Earthquakes. What if you knew the epicenter was . 572 . km from Vancouver?. Earthquakes. What if you ALSO know that it is . 884 . km from Prince Rupert?. Earthquakes. Finally, you also know that the epicenter is . 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. . 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.. Referencing and Repeatability. "Referencing" is a dual process of positioning the workpiece relative to the . workholder. , and the . workholder. relative to the cutting tool. .. If a part is incorrectly placed in a . 8. th. Grade Earth and Space Science. Class Notes. Earthquake Magnitude and Intensity. Richter scale . – measures the . magnitude. (energy) of an earthquake.. Determined by the . amplitude. (height) of the seismic wave. . What Is an Earthquake?. An . earthquake. is the vibration of Earth produced by the rapid release of energy. Energy released radiates in all directions from its source, the . focus. . Energy is in the form of waves. Creation. Flood. Crucifixion. Los Angeles sinking.
