Chapter 26, Problem 10TE

To determine

The type of fault associated with the 1964 earthquake in Alaska.

Answer to Problem 10TE

The type of fault associated with the 1964 earthquake in Alaska was the Aleutian Mega thrust, a converse issue brought about by a compressional force.

Explanation of Solution

To deform the rock because the rock is brittle, rock fractures into separate blocks. These blocks move relative to others, this fracture is called a fault.

The movement along a fault can happen rapidly and produce an earthquake or gradually over time without occurring of significant earthquakes. The fault that is caused by the compressional forces is called reverse fault. The 1964 Alaska earthquake is having a magnitude of 9.2, occurred along a reverse fault.

Conclusion:

Therefore, the type of fault associated with the 1964 earthquake in Alaska was the Aleutian Mega thrust, a converse issue brought about by a compressional force.
