The difference in arrival times of P and S waves.
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.
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.
The epicenter can be determined by measuring the time difference between the arrival of P and S waves, and then calculating the distance of the epicenter from each of the 3 stations. Once you have estimated the distance for each station you then draw a circle around each one. The place where the circles meet or intersect, is the epicenter.
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
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).
The difference between the Focus and the Epicenter is...... The Focus is pretty much where the earthquake starts but some people say it is the center of the earthquake. But moving on the Epicenter is right above the Focus but on the crust. I hope that answered your question!!
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
The epicenter is the origin of an earthquake. However, a hypocenter is the exact spot where a bomb has been dropped.
An earthquake can reach several miles in distance, but the epicenter is the point of the strongest movement, usually the starting point from which it spreads. Also, the epicentre is on the ground directly above the focus. The focus is the point where the actual earthquake occurred. Hope this helped:)

The difference between the two seismograph readings could tell you where the epicenter is located.
