Description:

Question: The San Andrea is an active fault zone, marked by frequent earthquake activity. The crust southwest of this strike-slip fault (including Los Angeles) is sliding to the northwest relative to the other side. It is possible to estimate the average annual rate of movement by recognizing rock of an earlier geologic age that have been cut and offset by the lateral movement along the fault. Below is a generalized geologic map of southern California, which shows Pliocene-Miocene age rocks offset along the San Andreas fault. The age of these rocks have been determined to be 25 million years. What is the average annual rate of movement in centimeters per year along the San Andreas fault?
