Earthquakes occur each hour, day, week, month, etc. Many go barely noticed while others turn catastrophic. Recall the December 26, 2004 Sumatra earthquake, tsunami, and aftershocks. Learn about causes and consequences of earthquakes and why we can't yet predict them. Learn about non-earthquake events that send tremors through our planet and alter its evolution, locating and classifying earthquakes, plate tectonics, and using earthquakes to CAT-scan the Earth.
Examination of the earth from a planetary perspective: how the Earth and the planets formed; what the other planets tell us about the Earth; and how the Earth continues to evolve through continental drift, earthquakes, volcanoes, and mountain building. Emphasis on large-scale processes and features including the implication of meteorite impacts, nature of the deep interior, formation of the oceans and atmosphere, and origin and evolution of life.
Elastic theory, seismic waves, seismometers, ray paths, travel times; internal structure of the Earth; earthquakes: location, characteristics, origin, mechanism and relation to plate motions. Prerequisites: Physics 135-2, Math 221. No previous geology background required; students with other science backgrounds welcome.
