disaster and risk management

1. Activity: Areas or Location exposed to
Hazards

2. EXPOSURE &
VULNERABILITY

3. LEARNING OUTCOMES:
Enumerate different elements exposed to hazards.
Explain the meaning of vulnerability.
Discuss why certain sectors of society are more
vulnerable to disaster than others.
Reason out why certain structures are more
vulnerable to specific hazards than others.

4. WHAT IS EXPOSURE?

Examples: poor design and construction of buildings,

9. VULNERABILITY TO SPECIFIC HAZARDS
(ADPC, 2012)
POOR DESIGN AND CONSTRUCTION OF BUILDINGS AND
OTHER INFRACTRUCTURES
INADEQUATE PROTECTION MEASURES OF ASSETS
LACK OF PUBLIC INFORMATION AND AWARENESS
LIMITED OFFICIAL RECOGNITION OF RISKS AND
PREPAREDNESS MEASURES
DISREGARD FOR WISE ENVIRONMENTAL MANAGEMENT

10. TYPES OF VULNERABILITY (UNISDR)
1.PHYSICAL VULNERABILITY
2.SOCIAL VULNERABILITY
3.ECONOMIC VULNERABILITY
4.ENVIRONMENTAL VULNERABILITY

to a particular hazard and briefly state their
vulnerabilities.
