GEOLOGY 1 Lecture Notes - Lecture 28: Scientific Method, Return Period, Hurricane Mitch
Document Summary
Most natural hazards have been identified and studied using the scientific method and are predictable through scientific evaluation. Risk analysis: a critical component in understanding the impacts associated with hazards. Hazard planning and hazard mitigation are important. Studying links between hazards: spatial and temporal links. Links between past, present, and future conditions. Links between hazards (e. g. volcano and mudflow) Geologic setting and hazards (e. g. rock fractures and landslides) Risk estimate: product of probability and consequences. To human life: potential loss and injury of life. To society: services and functions of society. To economy: manufacture, mining, commercial, real estate, etc. Increases in population put a greater number of people at risk. Land use change amplifying the impact risks of natural hazards. Deforestation and fire in honduras before hurricane mitch, 11,000+ dead. Inappropriate construction code in tectonic earthquake zone, 2003 iran earthquake, ~300,000 people dead.
