Title: Earthquake Magnitude and Intensity PDF
Url: http://www.geology.siu.edu/people/pinter/pdf/EQMagIntensity.pdf
Creator: Pinter, Nicholas
Publisher: Southern Illinois University at Carbondale. Dept. of Geology
Description: In this exercise, students compare the amount of shaking caused by historic earthquakes, and use data from seismograms to determine Richter magnitude. They will also investigate moment magnitude, an alternative to Richter magnitude, and calculate a seismic moment. In the second portion of the exercise, students investigate earthquake intensity and prepare a map of intensity values from the 1994 Northridge, California earthquake, using actual reports of its effects. Introductory materials explain the difference between earthquake magnitude and intensity, point out the logarithmic nature of the Richter scale, and present criteria for assigning modified Mercalli intensity values to a particular location. The exercise includes instructions, maps, data, and study questions. A bibliography is also provided.
