Which two waves from an earthquake can triangulate the epicenter?
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
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.
What is the fewest number of seismograph stations that must record the arrival time of P and S waves in order for the epicenter of an earthquake to be located?
Three

What type of data do geologists use to locate an earthquake's epicenter?
Seismologists use the data from triangulated seismographs to locate an earthquake's epicenter. The difference in time between the arrival of p and s waves at a seismometer tells the distance to the epicenter of an earthquake. To get the exact location, scientists must collect data from at least three seismometers. The point where all three circles is the epicenter of the earthquake. +++ The Epicentre is generally obvious: it is the point of maximum disturbance on the surface. The centre of the actual slip is the Focus, and this has to be calculated from seismograph data by triangulating from wave velocities.

How do you find the epicenter of an earthquake by seismic data?
By finding the arrival time of the P waves and S waves :)
What difference between P-waves and S-waves is used to find an earthquake's epicenter?

How do seismographs approximate the location o an epicenter?
The farther apart the arrival times of the different waves are, the farther away the earthquake is. :)

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.
