Resource Type:Classroom Activities; Curricula and Instruction
Grade Level:
5 6 7 8 9 10 11 12
Organization:Incorporated Research Institutions for Seismology (IRIS)
Summary:In this activity students explore the rate of earthquake occurrence for areas of Earth they choose to explore. Data is accessed through the simple interface of the IRIS Earthquake Browser (See Related Resources above). After compiling their data for various sized earthquakes, students calculate re-occurrence intervals for each magnitude and plot the data on a semi-log graph for interpretation.  Discussions of the collected data touches on strengths and limitations of their data set, possible societal implications (e.g. building codes etc), as well as concepts related to earthquake prediction and forecasting.
