Question

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 longterm average, not the expected movement each year.
Total offset in centimeters (or inches):___centimeters (or inches)
Average offset per year:___ centimeters per year (or in./yr.)

Answer 1

Answer:

a. It is given that the Wallace creek has been offset by 130 meters.

Therefore, total offset = 130 m =13000 cm

b. It is also provided that the offset  began 3700 years ago. Therefore average offset per year:

Total offsets ÷ No. of years = 13000 ÷ 3700

= 3.5123 cm per year
