1. Disaster Risk Section 1.2

2. Objectives At the end of the lesson the students should be able to: Enumerate the elements of disaster risk, Measure the relative levels of disaster risk of different areas that are exposed to, and Explain how the use of maps influences the adoption of measures to reduce the levels of disaster risk.

3. World Risk Map (Hermes, 2014)

4. The Elements of Disaster Risk When people encroach on hazardous areas and urban centers continue to grow along the path of hazard events, the magnitude of disasters is expected to increase. Disaster risk =function[Hazard, Exposure, Vulnerability]

5. Estimating Disaster Risk

6. Risk Assessment Risk assessment estimates the impact that a hazard would have on people, services facilities and structures. The magnitude of the disaster depends on The severity of natural events Quantity of the exposure of the elements at risk includes lives and properties Vulnerability level or quality of exposure

7. Minimizing Disaster Risk Reduction through Reduction of Exposure and Vulnerability

8. Level of vulnerability can be reduced by keeping people and property away as far as possible from hazards. Relocating people must come in hand with other preparedness measures.

9. Classifying areas according to landslide risk by combining a landslide hazard map with an exposure and vulnerability map HIGH MEDIUM LOW HIGH MEDIUM LOW A B c D e f G h i LANDSLIDE HAZARD EXPOSURE AND VULNERABILITY RISK MAP Where would you advise interested entities to purchase an existing residential or commercial building? Which site will you recommend for further development? Mark FD?

10. Assessment Section What are the elements of disaster? Explain the significance of each element of disaster risk in determining the odds of a disaster impacts. How would people, business sector, and government institution benefit from measuring the relative level of disaster risk? Given the occurrence of the natural hazardous phenomena cannot be prevented, discuss in terms of elements of disaster risk ways by which disaster and disaster risk can be minimized
