D.R.R.R REVIEWER 1st Quarter LESSON#1 CONCEPTS OF 2022 WORLD RISK REPORT DISASTERS Philippines Ranked as the FIRST (highest) country at risk to disaster DISASTER A serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure, vulnerability and capacity, leading to one or more of the following: human, material, economic and environmental losses and impacts. (UNISDR) What are the WRI indicators? EXPOSURE Exposure to hazards (cyclones, earthquakes, etc.) SUSCEPTIBILITY Population’s access to improved sanitation, etc. COPING CAPACITY Corruption perception index, insurance coverage, etc. ADAPTIVE CAPACITY Adult literacy rate, combined gross enrolment ratio, gender parity in education, etc. KEY FACTORS 1.

HAZARD Natural phenomena that might impact an area or a region. LESSON #1.9 EARTHQUAKE & Hazards are there regardless of EARTHQUAKE HAZARDS whether there is anyone present to experience them or not. MEASURED: units of energy and strength of shaking RISK Anything that could potentially be lost when the hazard occurs. MEASURED: fatalities or amount of damage.
