Summary
Seismogram: Image created by Crickett.Seismogram: Image created by Crickett.Using the excellent Virtual Courseware - Earthquake program, students learn how to read a seismogram and use them to triangulate the epicenter of an earthquake. This program leads students step by step through the entire process of measuring the epicenter and calculating the magnitude of an earthquake. There is also an assessment tool associated with the program so that you can monitor how well your students did on the review quiz at the end of the activity.

Objectives
Can identify p and s waves on a seismogram.
Can calculate the distance from an earthquake epicenter to a seismographic station using p and s wave time difference.
Can triangulate the location of an earthquake epicenter.
Can determine the magnitude of an earthquake.
Can find the latitude and longitude of a place.
