Explain the process of risk analysis. 2. Explain what is risk. 3. Compare and contrast quantitative and qualitative approaches to risk analysis. 4. Identify and discuss approaches related to using historical data in determining risk. 5. Explain the concept of uncertainty and how it impacts risk analysis. 6. Discuss the concept of acceptable risk and how we determine it. 7. Explain how we describe the likelihood and consequences of risks.

By doing so we explore the likely impact of the hazards on the community. Risk analysis is the determination of likelihood and possible consequences from a disaster. This analysis must be accomplished in a systematic basis so as to provide useful and accurate information for decision makers through risk management or community hazard mitigation initiatives. Our goal is to provide the right information at the right level of complexity and detail to decision makers at the right time. The Process of Risk Analysis Risk analysis therefore takes information from the hazards identification and examines not only the probability of the event but also explores the social-cultural economic and environmental adverse impacts from a disaster. Risk analysis goes further to then compare various hazard risks to determine if various risks could have a similar likelihood of occurrence and outcomes. The results of the risk analysis can be used in
