Virtual Earthquake
This interactive feature shows students how an earthquake epicenter is located and how Richter magnitude is determined. They will use recordings of seismograms from three stations (provided in the activity), learn the difference between the focus and epicenter of an earthquake, and that the magnitude of an earthquake is an estimate of the amount of energy that it has released.
