sections of active faults that haven't experienced significant earthquakes for a long period of time

Earthquake

vibrations in the ground that result from movement along faults, or breaks in the crust

seismic gaps

A giant wave usually caused by an earthquake beneath the ocean floor.

Tsunami

break or weakness in Earth's crust
