How can scientist tell how far the epicenter of an earthquake is from a seismometer station?

They need three stations to accurately tell where the location of something is. By measuring the time where it hit one station to the next, they can determine its location through a process called triangulation.

What can you figure out about an earthquake from only one seismic station?
the distance to the epicenter
How many seismograph-station readings are needed to pinpoint the epicenter of an earthquake?
Three
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.
What is the number of seismic stations need to find the epicenter of an earthquake?
Technically you just need one, but the more there are, the easier it is to locate the epicenter of the earthquake. The reason for this is that based on the timing of each of the three seismic waves that reach the station, the station can calculate a radius all around the station. So picture a circle with what the radius is around the station, another station will do the same thing, and there HAS TO BE an intersection of these circles somewhere, so that narrows down the location of the epicenter. Hope this makes sense.
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.
How many seismometer-station readings are needed to pinpoint the epicenter of an earthquake?
At least three.Please see the related question for an explanation as to why.A minimum of three seismograph or seismometer stations are required to locate the epicentre of an earthquake.
How is the fact that P-waves travel faster that S-waves used to determine the distance of an earthquake epicenter from an seismograph station?
Using the difference in their arrival times and an estimate of their velocity of propagation you can calculate the distance of the earthquake epicentre from the seismometer recording station. If you do this from three or more different seismometer stations you can triangulate it's position. For more information please see the related question.
How do you use circles to find the epicenter of an earthquake?
Scientists can calculate the distance that an earthquake occurs from a seismometer station by looking at the record of the seismic waves and measuring the difference in time between the arrival of P and S-waves. This gives them a distance but not a direction. So they plot this distance on a map by drawing a circle round the seismometer station. The radius of this circle is equal to the distance to the epicentre. If this is done for one other seismometer station that has recorded the earthquake then the circles will intersect in two places. If you add in a 3rd station and so a third circle they will all intersect in one place - the epicentre of the earthquake. In reality this process is automated by computer and lots of readings from lots of stations are used.

How is magnitude measure using Richter scale?
The Richter scale assigns a magnitude number to an earthquake based on the maximum amplitude of the seismic waves as recorded on a seismometer and the distance of the seismometer station from the epicentre of the earthquake.
