What can the time lag between the first arrival of the P-wave and first arrival of the S-wave be used to determine?

Answer 1

Difference in arrival times between P and S waves can be used to determine the distance between the station and an earthquake.

Since different waves travel at different speeds, they arrive at seismic stations at different times.\/li>
The difference in arrival times between P and S waves can be used to calculate the distance between an earthquake and a station.\/li> \li>By calculating the distance between three stations and the earthquake, we can draw a circle around each station with a radius equal to the earthquake's distance from it. The earthquake happened at the intersection of all three circles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
