Question

What happens to the lag time (difference in arrival times between P-waves and S-waves) with increasing distance from the earthquake epicenter? The P-S lag time increases The P-S lag time remains the same The P-S tag tone decreases There is no P-S lag tone (it is zero) Below is an animation showing the differences between how dry sediments and saturated sediments react when subjected to an earthquake. Play both the dry compaction and liquefaction portions of the animation. Then Use the information you learn to answer the following question. (You must have Flash installed or your computer in order to view this animation.)

Explanation / Answer

Question 9

Answer: The p-s lag time increases

The p s lag time increases with increasing distance from the earthquake epicenter.

This is because of intensity of earthquake waves are decreases with increasing distance form epicenter.
