susceptibility to natural disasters in emerging economies differs from the The average annual damage from natural disasters over cation of Global Natural Disaster Risk Hotspots (Hotspots) project was IFPRI: ciofreedopadkin.ga FAOSTATS. Appendix A. Dominica: Natural Disasters and Economic Development in a Small Island State able at ciofreedopadkin.ga
The amount of casualties certainly does, but the damage will be the same no matter when the earthquake occurs. Cinder cones are small. What about eruptions from volcanoes like Yellowstone or Long Valley?
The best evidence that global warming is occurring is that average global temperatures have increased over the last years. The evidence does not come from metling ice or the amount of Carbon Dioxide in the atmosphere.
The evidence comes from measuring temperatures and this evidence cannot be disputed. This point was emphasized many times in class, in homework, and on the mideterm. The letter I, as in Isaac, is not the 5th letter of the alphabet, it is the 9th, and thus Isaac was the 9th tropical storm or hurricane of Life or Death Questions. Several questions on the final exam were designed to see if you learned some valuable life or death lessons.
The results are discouraging. That's 28 deaths in a course in which you were supposed to learn how of avoid deaths by natural disasters.
You are here
Some people died more than once, but I did not keep track of those statistics. Hopefully those of you who potentially died in these situations will read about your errors here before reality strikes. Congratulations to those of you who are graduating, and best wishes for a great summer to all.

These comments may be helpful and you can find these old announcements from previous semesters by clicking HERE. January 23, Because of the freeze day last week, I have had to revise the syllabus. The links above will now take you to the revised version of the Syllabus. Note that assignment due dates and the midterm exam date have changed. March 13, I have finished grading the midterm exam and I will pass it back in class today.
To see the distribution of scores and comments on the exam click HERE. May 11, Final exams have been graded and scores have been posted to Canvas look under assignments. Grades have been posted to Gibson. If you want to see your final exam or have any questions about your scores or grades, please feel free to come by my office, Room Blessey Hall, or you can send e-mail. It is probably best to make an appointment, as I am in and out of my office now that the semester is over.
What truly is amazing is that many of the comments below are the same comments I posted after the previous semester's final exam and have been posted on this web site during the entire semester. So, I can now retire. A national training program, supported by the federal government and fully integrated with the preparedness training proposed here, should be developed for this purpose.
Its curriculum would include land-use planning, zoning, building codes and regulations, tax incentives, and nonstructural mitigation measures. Case studies from throughout the nation and around the world should be included. Mitigation training should be highly interactive, reflecting real problems and issues. For example, how can hazard and risk data be used to promote mitigation at the community level? How can hazardprone land be used in ways that are important to communities but less vulnerable to natural disasters?
How can a local emergency manager or other official develop a cost-effective mitigation program? How can mitigation policy and practice be moved up on the political agenda? How can local commitment to hazard reduction be developed? How can historic structures be cost-effectively protected to avoid expensive salvage attempts following a disaster? These and other issues need to be addressed in a nationwide training program. Hazard-specific research. Recent disasters have demonstrated the benefits of mitigation efforts while pointing out the need for research to improve mitigation practice.
Although all hazards would benefit from such study, research agendas for earthquakes, landslides, and extreme winds are illustrated below.
Earthquakes: There is a need to complete a national seismic monitoring network and establish a cooperative international program in strong-motion measurement and data analysis. Local networks should be established, as needed, to determine the effects of local site conditions on ground motion and the relationship between specific ground motion parameters and the degree of structural damage.
The behavior of structures founded on different soil types is another area of research opportunity. The damage distribution in the Marina District during the Loma Prieta earthquake dramatized the effects of soil properties on structures and underscores the need for additional research in this area. Research is needed to develop cost-effective methods for strengthening existing buildings and structures, especially unreinforced masonry and brittle reinforced-concrete buildings.
Federal and state governments should encourage the development and implementation of active and passive control systems and other new techniques to improve the seismic resistance of both existing and new buildings. Additional research should be conducted to improve techniques for controlling damage to nonstructural elements such as ceilings, windows, the electrical supply, and domestic gas pipes.

Research to improve the design and construction of lifeline systems should be accelerated. Better understanding of the conditions that generate landslides would significantly improve hazard and risk assessments by local jurisdictions.
Research is needed to develop designs that mitigate ground deformation and damage to structures, provide a technical base for mitigation measures such as landslide zoning, and test and evaluate innovative landslide stabilization techniques. The application of new techniques in satellite remote sensing, geophysics, and geotechnical engineering for delineating landslide hazard areas should be accelerated.
Research is needed to identify the economic, political, and social processes that encourage or impede landslide mitigation programs.
This information could be valuable when landslides are considered in insurance programs and local planning and zoning, including the location of key facilities. Extreme winds: Knowledge about wind-force effects on buildings is critical to developing wind speed provisions in building codes and designing wind-resistant structures. Research in this area is lacking; measurements of wind speeds at the height of mid- to high-rise buildings are rarely available.

A national wind hazard reduction program, modeled on the National Earthquake Hazard Reduction Program, is needed to improve building performance in high winds and severe weather. The program should emphasize mitigation. Schools and medical facilities, in particular, should be subject to stringent building codes.
High winds can cause substantial property damage and economic loss.
6 The Impact of Natural Disasters : Simplified Procedures and Open Problems
Research needs to focus on whether current mitigation practice, including the wind-resistance provisions of building codes, is responsive to the potential magnitude of the problem. Overcoming resistance to mitigation.Such standards should be considered for all publicly funded infrastructures and lifelines such as highways and bridges. The characteristics of a hurricane are described in detail at the NASA website.
