PART 1, Answer Sheet, Earthquake Intensity, San Andreas Fault

1  What two plates are separated by the San Andreas fault?
 
 

2  How far has the part of rock X on the southwest side of the fault (that's the part closest to San Francisco) traveled relative to the part on the northeast side of the fault?
 
 

3  Assuming that movements along the fault have been relatively consistent, calculate approximately how many earthquakes (at 5 meters displacement per quake) could have occurred over the past 25 million years?
 
 

4  What has been the average rate of movement along the fault over the past 25 million years, in km/million years?  in cm/year? (NOTE: 1 km = 1000 m; 1 m = 100 cm; 1 million years = 1,000,000 years.)
 
 

5  How many years will it take for Los Angeles to move up next to Oakland?
