Welcome to Virtual Earthquake

Virtual Earthquake is an interactive computer program 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 computer program is running on a Web Server at California State University at Los Angeles. You can interact with Virtual Earthquake using your Web browser.

Instructors: here is some important information

Virtual Earthquake will show you the recordings of an earthquake's seismic waves detected by instruments far away from the earthquake. The instrument recording the seismic waves is called a seismograph and the recording is a seismogram. The point of origin of an earthquake is called its focus and the point on the earth's surface directly above the focus is the epicenter. You are to locate the epicenter of an earthquake by making simple measurments on three seismograms that will be sent to you by the Virtual Earthquake program. Additionally, you will be required to determine the Richter Magnitude of that quake from the same recordings. Richter Magnitude is an estimate of the amount of energy released during and earthquake.


Upon completion of this activity you will be given the opportunity to receive a personalized Certificate as a "Virtual Seismologist."

In order to get this certificate, you must make careful measurements throughout the activity. The actual certificate is much larger than the one displayed above.
