Exposure and Vulnerability

These are the main determinants of disasters.

Hazard

This refers to the probability of occurrence at a given magnitude

PhExp

This refers to the physical exposure of the affected area.

Exposure

This refers to the total population living in the affected area for each event.

Vulnerability

This refers to the degree of loss to a given element at risk at a certain severity level.

Economic vulnerability

This is the susceptibility of individuals, communities, business, and governments to absorb or cushion the effects of a hazard event.

Essential facilities, Industrial and high potential loss facilities and facilities containing hazardous materials, Transportation lifelines, Utility lifelines
