Comparing Ground Motion from Earthquakes
Students use data provided in REV (Rapid Earthquake Viewer) to compare the amplitude of the seismic waves recorded as a result of ground shaking from recent earthquakes. They explore the concept of a logarithmic scale, and create a graph using a logarithmic axis. By graphing and comparing data for earthquakes of different magnitudes recorded at similar distances from the epicenter, students discover that the amount of ground motion recorded by a seismometer is a measure of magnitude.
