The distance between a seismological recording station and the earthquake source is determined from the arrival time of P and the S waves. P waves are faster than S waves and surface waves.
The distance between a seismological recording station and the earthquake source is determined from the arrival time of P and the S waves. P waves are faster than S waves and surface waves.
determining the distance from the earthquake by three recording stations.
The three stations' rings that showed the distance from the epicenter and in that area would be where the epicenter is.
The amplitude of seismic waves as measured by a seismometer and the distance of the seismometer from the earthquakes epicentre. Please see the related question for more information.
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.

determining the distance from the earthquake by three recording stations.
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.

Magnitude is how much the earth moved during an earthquake and is determined by the distance the marking device moves above and below the straight line on a seismograph.
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.
Echogram
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.
The more is the time taken and the distance recorded by the seismograph, the more is the effect of an earthquake:)
