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.
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
true
The distance to the epicenter
The difference in arrival times between P and S-waves as measured on a seismometer can be used to determine the distance to the origin.
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
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!
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.

surface waves
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
