Surface wave

  Select the term that matches the below definition. The area below the surface of the Earth where the earthquake occurs, also called the hypocenter. This is the area where the fault begins to rupture, releasing energy. Question 2 1 pts Select the term that matches the below definition.

Question 26 10 pts Refer to pp316-317 in your lab manual. Answer this portion of question 2: Questionnaires designed for assigning Modified Mercalli scale intensities to the October 17 earthquake were returned from the locations shown on Figure 16.12. These responses were divided into five groups, as shown in Table 16.2. Using these responses, assign Modified Mercalli scale intensities to the five groups...using Table 16.1 as a guide. In your answer, you may type 'A - MM scale VII; B - MM scale IV'; etc. for A through E. In addition, is the Modified Mercalli scale an accurate and precise way to measure earthquakes?
