S-waves and P-waves emit from the focus (epicenter) at the same time, yet one of them is faster than the other. therefore the S waves and P waves are directly proportional to each other. So all one needs is to do the math and trace the distance between the waves and there, you have found the Focus (epicenter) of the earthquake.
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
the find the epicenter the find the focus from the epicenter
At many different earthquake centers. When an earthquake happens the tree nearest earthquake centers record the magnitude and intensity of the seismic waves produced by the earthquake in order to find the origin or epicenter
This job would normally be undertaken by a type of geophysicist known as a seismologist rather than a geologist. For information on how seismologists locate seismic waves, see the related question.

epicenter and seiesmic waves, find the distance and seismograph stations

By finding the arrival time of the P waves and S waves :)
you have to find the s and p to find and then you have the awnser
the find the epicenter the find the focus from the epicenter
At many different earthquake centers. When an earthquake happens the tree nearest earthquake centers record the magnitude and intensity of the seismic waves produced by the earthquake in order to find the origin or epicenter
so that one observation can relate to another set of imformation gatherd
You need to find how many km the earthquake is

Geologists use circles to find the epicenter of an earthquake.
