Wallace Creek has been offset by 130.0 meters (430 feet) to the right along the fault. The age of stream deposits indicates that this offset began 3700 years ago. Based on these figures, calculate the average rate of movement along this segment of the fault in centimeters per year (or inches per year). Keep in mind that your answer is an estimate of the long term average, not the expected movement each year.

A. Total offset in centimeters (or inches)

B) Average offset per year

1. This requires simple math. If the fault has moved 130 meters, how many centimeters is that? 430 feet equals how many inches? You have to know how many inches are in a foot, etc. Then divide by 3700 (years) to discover how much movement per year is average.
