Measuring Earthquakes: Intensity Maps

Measuring Earthquakes: Intensity Maps

This set of exercises will introduce students to the construction of earthquake intensity maps, familiarize them with the Modified Mercalli Intensity Scale, and give them the opportunity to build their own maps online in order to locate the epicenter of an earthquake. In the first exercise, they will use intensity data from the 1986 North Palm Springs, California earthquake to create an isoseismal map. In the second, they will use a special interactive page of dynamic HTML to plot intensities that they assign based on reports, and attempt to determine the epicenter based on the area of highest intensity.
