WebMeasure the difference in arrival times between the first shear (s) wave and the first compressional (p) wave, which can be interpreted from the seismogram. Multiply the difference by 8.4 to estimate the distance, in kilometers, from the seismograph station to the epicenter. 00:00 00:00 An unknown error has occurred Brought to you by Sciencing WebYou can observe the P- and S-wave arrivals on a seismogram to calculate how far away an earthquake was from your station. A traveltime curve is a graph of arrival times, commonly P or S waves, recorded at different points as a function of distance from the seismic source.
