__Glossary __ Aftershock: An aftershock is an earthquake that occurs after a larger earthquake in the same area.

Anticline:

Base-isolated Building:

Compression: Stress that squeezes rock until it folds or breaks

Deformation:

Epicenter:The point on Earth's surface directly above an earthquake's focus.



Fault: A fault is a fracture along which the blocks of [|crust] on either side have moved relative to one another parallel to the fracture.

Fault-block Mountain: A mass of rock bounded on at least two opposite sides by faults. Fault-block Mountain

Focus:

Folds:

Footwall: The footwall is the block of rock that forms the lower half of the fault.



==Hanging Wall: The Block of Rock that Forms the Upper Half of a Fault. ==
