The time lag between the arrival of the different types of seismic waves is a function of distance from the earthquake focus.

Question

Quizplus · Accepted Answer

This is a true statement. The time lag between the arrival of the different types of seismic waves (P-waves, S-waves, and surface waves) is directly related to the distance from the earthquake focus. P-waves are the fastest and arrive first, followed by S-waves, and then surface waves. The further away from the focus, the longer the time lag between the arrival of the different types of seismic waves.
