The difference between the arrival times increases as the distance from an earthquake epicentre increases as S-waves travel more slowly than P-waves so the greater the distance the further they lag behind.

Do Geologists use the difference in the arrival time of P and S waves at a seismograph to determine the magnitude of an earthquake?
No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.
How is the distance between a seismic station and the earthquake epicenter is determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
Given the difference in arrival times, you can determine the distance from the epicenter.
Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
Where is the epicenter of an earthquake if the arrival time difference between P and S waves is zero?
Your standing on it! P-waves travel faster than S-waves through the Earth. As such the further away a seismometer station is from the epicentre of an Earthquake, the larger the difference between arrival times will be. By the same logic this means that the closer you get to the epicentre, the smaller the difference in arrival time will be until your at the epicentre when the difference will be zero!
What is the difference in arrival time between P and S waves equivalent to?
This value is related to the distance of the seismometer station from the earthquake's epicentre. The larger the difference in arrival times, the greater the distance.
What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.

The distance between an earthquake epicenter and the location of a seismograph can be calculated because?
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
What happens to the distance in arrival times between P waves and S waves as the distance for the earthquake increases?
surface waves
Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.

How do scientists find the distance of an epicenter from a seismograph?
They measure the difference in arrival times of P and S seismic waves as measured on a seismograph. From this (based on an estimate of their relative velocities) they can calculate the distance of the seismometer from the earthquakes epicentre using the following equation:Distance to epicentre (km) = Time Difference (s) x (VP - VS) / (VS x VP)Where:VP = P-wave velocity (km/s)VS = S-wave velocity (km/s)
