This course presents an introduction to the most excitingand sometimes terrifyingmanifestations of life on a dynamic planet. The class will explore scientific study of earthquakes and volcanic eruptions, as well as their implications for society. We will examine fundamental geological processes, focusing on the new theory of global earth dynamics known as plate tectonics. We will document the effects of earthquakes and volcanic eruptions, including the wide range of secondary effectssuch as landslides, mud flows, and tsunamis (tidal waves)that accompany these natural disasters. Finally, we will examine the effects of earthquakes and volcanic eruptions on human societies, and approaches to mitigation of natural disasters.
The class will use one main textbook: Patrick Abbott's Natural Disasters, 8th Ed. (McGraw-Hill, 2011). The lab manual, also required for the course, is Earthquakes and Volcanoes: Lab Manual, 4th ed. by James Brophy and Michael Hamburger (Pearson, 2007). Both books should be available at the I.U. Bookstore and T.I.S. The two textbooks, as well as additional readings, will be on reserve in the Geology Library, located on the 6th floor of the Geology Building. Supplemental readings will be posted on Oncourse.
Your grade in the course will be based on two quizzes (10%), in-class and take-home exercises (20%), a mid-term (15%) and final examination (25%), and laboratory or discussion exercises (30%). Examinations will include a mixture of multiple-choice, short-answer, and essay questions. Students will not ordinarily be permitted to make up quizzes, examinations, and laboratory exercises.
The laboratory sessions will emphasize a quantitative, scientific approach to examining the fundamental physical and chemical processes in the Earth that are responsible for earthquakes and volcanic activity. The labs will also emphasize the application of seismological and volcanological knowledge to problems of natural hazard reduction. Some of the laboratory exercises will involve application of computer programs. Although most lab exercises will involve group efforts, the written material handed in must represent your own work!
Attendance at lectures and labs is required! There will be in-class exercises that will count toward the final grade; there will be no make-up for missed in-class exercises. Exam questions will emphasize components from readings, classroom lectures and labs/discussions.
Warning: Low attendance will turn scheduled quizzes into pop quizzes!
Academic misconduct, in the form of cheating, fabrication, plagiarism, or interference, will not be tolerated. Violations will be referred to the IU Office of Student Ethics. Note that sale of notes from this class is prohibited. Students violating this rule will be expelled from the class. Questions?
