How is the epicenter of an earthquake determined? First you need to understand that the different types of seasmic wave travel at different speeds. The p-wave travels faster... ... The further the seismograph is from the epicenter of an earthquake, the greater the difference in arrival times for these two waves. So,

The waves recorded on a seismograph show the time-lag between the arrival of the faster P waves and the slower S waves. This time-lag can be converted to a distance from the seismograph to the earthquake epicenter. If the distance from thre...

Virtual Earthquake is an interactive Web-based activity designed to introduce you to the concepts of how an earthquake EPICENTER is located and how the RICHTER MAGNITUDE of an earthquake is determined. The Virtual Earthquake program is running on a Web Server at California State University at Los Angeles.

LAB 5: (20 pts) The purpose of this lab is to help you understand how how the epicenter of an earthquake is determined. Because P and S waves travel at different velocities, The P wave arrives at a seismic station ahead of the S wave.

In order to locate the epicenter (surface location) of an earthquake, we examine seismograms recorded by at least three different seismic stations. Recall that P and S waves travel at different speeds, so we can use this difference to figur...
