“Earthquake Hazards Program,” from the U.S. Geological Survey, puts together materials about the past, present, and future of earthquakes, including current and past earthquake activity, research, seismic networks, and regional centers. Did you know the biggest earthquake in the world last century was in Chile on May 22, 1960, with a magnitude of 9.5 Mw? Or that, in the United States, the two states with the most earthquakes are Alaska and California? Or that Florida and North Dakota have the smallest number of earthquakes in the United States? Under the Earthquake Education section, educators should check out “Earthquake ABCs,” “Today in Earthquake History,” and “Cool Earthquake Facts.” Students can learn how to become a geophysicist and about earthquakes that potentially could rattle their classroom. The site is a wonderful reference for earth science teachers and includes a glossary of earthquake terms; common myths about earthquakes; and information on plate tectonics, measuring earthquakes, seismography, earthquake prediction, historic earthquakes, and earthquake preparedness.
