Tindog  Section 1.2 Objectives: 1. Enumerate the Elements of Disaster Risk. 2. Measure the relative levels of disaster risk that different areas are exposed to. 3. Explain how the use maps influences the adoption of measures to reduce the levels of disaster risk. 08/12/2024 Disaster Risk 7 8/12/2024 Disaster Risk 8  No Two Disasters are Alike Some are definitely similar, but appreciating their differences in terms of their nature and magnitude of triggering hazards, exposed elements at risk, and vulnerabilities will help us deal with potential disasters. Can you imagine how interventions to reduce risk can be applied effectively without prior disaster risk assessment? 8/12/2024 Disaster Risk 9  DISASTER RISK It is derive from the interaction of social and environmental processes and from the combination of physical hazards and the vulnerability of exposed elements. What is Disaster Risk? 8/12/2024 DISASTER RISK 10  WHAT ARE THE THREE ELEMENTS OF DISASTER RISK? R = H x E x V RISK HAZARD EXPOSURE VULNERABILITY​ This model is used by United Nations Development program (UNDP) and has been adopted by many, including the Philippines, in assessing risk. 11  Estimating Disaster Risk Earthquakes, torrential, rains, storms, etc. Resistance against Natural hazards People, property, etc. 12 RISK ASSESSEMENT Risk Assessment estimates the impact that a hazard would have on people, services, facilities, and structures. A Risk Map shows the hazards, effects (physical, social, and economic), vulnerabilities of areas, and costs of damages. 13  Estimating Disaster Risk At the disaster risk model implies, the magnitude of the disaster depends on the following: 1) The severity of natural event; 2) The quantity of exposure of the elements at risk, which include lives and property; 3) Vulnerability level or quality of exposure This model can thus be expressed as: Disaster Risk = Hazard x Exposure x Vulnerability 14 Minimizing disaster risk reduction through reduction of exposure and vulnerability. What will be the result in the reduction of vulnerability and disaster risk? Answer: Mitigation and Preparedness measures  Disaster Risk Reduction The level of vulnerability and exposure can be reduced by keeping people and property as far as possible from hazards. Relocating people to reduce vulnerability and exposure, however, is not simple matter of imposing an order which will be followed blindly by those affected. 17  The most vulnerable are the poor who are forced to live in dangerous area such as near volcanoes, flood-prone sites, and steep hillsides. Often, people consider the risks more acceptable than facing the curse of starvation away from very productive and fertile volcanic soils or river flood plains. 18 Do you live in an area prone to hazards? What hazards are you exposed to? Is relocating the best alternative to keep you safe? 19 Employee orientation 21  Risk Map: Hazard Map 7/29/20XX Employee orientation 22 7/29/20XX Employee orientation 23 Thank you! 24
