Professor: Seth Stein Lectures: Tues Thurs 12:30-1:50 PM, Tech F285
Defending society against natural hazards is a high-stakes game of chance against nature, involving tough decisions. How should a developing nation allocate its budget between building schools for towns without ones and making existing schools earthquake-resistant? Does it make more sense to build levees to protect against floods, or to prevent development in the areas at risk? Would more lives be saved by making hospitals earthquake-resistant, or by using the funds for patient care? What should scientists tell the public when—as occurred in L’Aquila, Italy, and Mammoth Lakes, California— there is a real but small risk of an upcoming earthquake or volcanic eruption? Recent hurricanes, earthquakes, and tsunamis show that society often handles such choices poorly. Sometimes nature surprises us when an earthquake, hurricane, or flood is bigger or has greater effects than expected from detailed hazard assessments. In other cases, nature outsmarts us, doing great damage despite expensive mitigation measures or causing us to divert limited resources to mitigate hazards that are overestimated. Much of the problem comes from the fact that formulating effective natural hazard policy involves combining science, economics, and risk analysis to analyze a problem and explore the costs and benefits of different options, in situations where the future is very uncertain. Because mitigation policies are typically chosen without such analysis, the results are often disappointing. This course uses general principles and case studies to explore how we can do better by taking an integrated view of natural hazards issues, rather than treating the relevant geoscience, engineering, economics, and policy formulation separately. We will consider thought-provoking questions that confront the complex issues involved.

Portable electronic devices may not be used in class. Please bring handouts to lecture. You may work with other students on the problems, if at the beginning of each assignment you list whom you worked with and on which parts. Problem sets are due one week after being assigned, unless prior arrangements have been made. Class question make-ups are only allowed by advance arrangements. As per university policy, class attendance is expected and required.
