First you need to understand that the different types of seasmic wave travel at different speeds. The p-wave travels faster than the s-wave. Therefore, p-wave will arrive at the seismogragh before the s-waves will. The further the seismogra...

This activity illustrates how the epicenter of an earthquake is found. I also will take them through the general process of how find the difference in arrival times of p- and s-waves can be used to find a distance to an earthquake and how using data from 3 seismograph stations is used to locate the epicenter.
