For the questions, you should know the following information about magnitude 5 through 7 carthquake Table 4 Magnitude and 7 of years Number of Earthquakes 5.0-5.9. 1973- 2003 (30) 25 6.0-6.9, 1872-2003 (131) 9 7.0-7.9. 1872-2003 (131) 3 Questions 1. What are some problems you might see with the data above? How significant are these trong (Hint: think about how averages work.) 2. Look at your M 4.0-4.9 data table. Berween March 24 and May 19. 1980, there were over 100 earthquakes between M 4.0-4.9. Why is this? 3. Should you include 1980 dara in your calculations or not? Why or why not? Fully discuss your answer a. 4. Fill out the following table using the instructions below: To calculate the average number of earthquakes in 1 year divide the total 1 number of earthquakes for each magnitude (calculated in tables 3 and 4) by the number of years in your data set. (Column 2 Column 3) b. To calculate the expected number in ten years by multiplying the average number of earthquakes expected in one year by 10. (Column 4 x 10) To calculate the time between earthquakes in days divide 365 days per year by the average number of earthquakes in one year. (365 / Column 4) d. To calculate the time between earthquakes in years divide time between carthquakes in days by 365 days. (Column 6/365) To determine whether your calculations are correct, think about the last column: time between earthquakes in years. Are the years between earthquakes increasing? They should be. How many magnitude 7 earthquakes have you experienced here in Oregon C. e.
