Earthquakes 1. How is most of the energy of an earthquake transported through the Earth's crust? 2. An earthquake that releases more energy is likely to do more damage. What other factors influence how much damage will be done by an earthquake? I. the distance of the region from the epicenter II. the distance of the region from a seismic detection station III. the type of construction in the region 3. The point below ground from which an earthquake's energy is released is called the focus. An earthquake's epicenter is located 4. What does the Mercalli scale measure? 5. Where does the energy released by an earthquake come from? 6. The seismic waves detected as the result of an earthquake can be either secondary S-waves, or primary P-waves. Which statement about S- and Pwaves is true? 7. Scientists measure S- and P-waves that are associated with earthquakes. What is the definition of a P-wave? 8. Earthquakes release energy that can cause damage to roads, homes, and buildings. Over time, scientists have developed several different rating scales to determine how much energy an earthquake has released and how much damage it has caused. Two of these measuring scales are the Mercalli scale and the Richter scale. Which of these is measured on a scale of 1 to 12? 9. Seismic waves can be measured and recorded by devices called _______. These devices record the seismic wave vibrations as jagged lines on paper. The stronger the vibrations, the more jagged the lines. These recordings are called _______. 10. Scientists measure the time between the arrival of an earthquake's _______ and _______ waves to help determine the distance between the recording seismograph and the earthquake epicenter.
