When you compare L,S,and P waves on the graph arrival time (Y axes)versus epicentral distance (X axes),the position of L waves will be below P waves.

Question

Quizplus · Accepted Answer

On a graph plotting arrival time (Y-axis) versus epicentral distance (X-axis), L waves (surface waves) would appear above P waves because L waves travel slower and therefore arrive later than P waves at any given distance from the epicenter.
