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?
