Question

URGENT How do you determine the difference in time between the arrival of the primary (P) wave and the arrival of the secondary (S) wave during an earthquake? (In other words, how do you determine T?)

Answer 1

Answer:

7) If you are asked to determine the arrival time of the P-wave and given a clock time for the arrival of the S-wave: Find difference in arrival time between P-wave and S-wave at the given epicenter distance, Subtract the difference in arrival time from the clock time of the S-wave.

I hope it help you....
