DLESELiving in Earthquake Country: A Teaching Box
7 lessons with the goal of teaching students about how and why earthquakes cause damage. Explores seismic waves, the ability of scientists to predict the likelihood and severity of earthquakes at specific locations, the difference between magnitude and intensity, the occurrence of earthquakes along patches of planar faults, and the potential damage caused by earthquakes such as landslides, liquefaction, or structural failure.
