JIBC Hazard, Risk, Vulnerability Analysis 5

Question 1

A 'multi-hazard risk assessment' is preferred over single-hazard assessments because it:

Accepted Answer

Identifies interactions between hazards and avoids conflicting mitigation strategies

Answer

Multi-hazard assessments reveal how different hazards interact and ensure mitigation actions for one hazard do not inadvertently increase risk from another.

Question 2

The term 'speed of onset' in hazard characterization describes:

Accepted Answer

How quickly a hazard develops and impacts a community after initial warning

Answer

Speed of onset measures the time between hazard initiation (or warning) and impact, which directly affects the lead time available for protective actions.

Question 3

In emergency management, 'critical facilities' receive priority consideration in vulnerability assessments because they:

Accepted Answer

Provide essential services needed for response and recovery operations

Answer

Critical facilities such as hospitals, emergency operations centers, and utilities must remain functional during and after a disaster to support response and recovery.

Question 4

When a risk analyst states that a flood has a '1% annual chance of exceedance,' this is equivalent to saying the flood has a return period of:

Accepted Answer

100 years

Answer

A 1% annual chance of exceedance corresponds to a 100-year return period, meaning such a flood is expected on average once every 100 years.

Question 5

The 'precautionary principle' in hazard management supports taking protective action when:

Accepted Answer

Scientific uncertainty exists but potential consequences are severe

Answer

The precautionary principle holds that lack of full scientific certainty should not delay protective measures when facing potentially severe or irreversible harm.
