CEM Hazard Identification & Risk Analysis 3

Question 1

A risk matrix that uses a 5×5 grid of likelihood versus consequence is primarily used to:

Accepted Answer

Prioritize risks by comparing their relative severity and probability

Answer

A 5×5 risk matrix provides a qualitative tool to prioritize which risks warrant immediate mitigation by plotting likelihood against consequence severity.

Question 2

Which FEMA tool uses a standardized methodology to estimate losses from earthquakes, floods, and hurricanes for mitigation planning?

Accepted Answer

HAZUS

Answer

HAZUS is FEMA's GIS-based loss estimation software that models physical, economic, and social impacts of natural hazards.

Question 3

Social vulnerability in risk analysis refers to:

Accepted Answer

Characteristics of communities that affect their capacity to prepare for and recover from disasters

Answer

Social vulnerability encompasses demographic and socioeconomic factors—such as poverty, age, and language barriers—that reduce a community's ability to cope with disasters.

Question 4

In event tree analysis, each branch after an initiating event represents:

Accepted Answer

A success or failure of a safety system or response action

Answer

Event tree analysis branches forward from an initiating event, with each node representing whether a safety barrier or response succeeds or fails.

Question 5

Which hazard characteristic describes the speed at which a hazard event develops and strikes an area, affecting warning time available?

Accepted Answer

Onset speed

Answer

Onset speed (or speed of onset) describes how quickly a hazard develops, which directly determines how much warning time is available to protective actions.
