Understanding Hazards

What is a hazard?

• A potential source of harm or adverse health effect on a person or persons

• A type of insurance policy

• A safety measure

• A warning sign

A disaster is:

• a natural or man-made event causing significant damage or disruption

• a type of weather phenomenon

• a planned event for entertainment

• a minor inconvenience

Fill in the blank: The risk equation measures the level of hazard risk for an area as risk = (frequency and/or magnitude of hazard × level of vulnerability) / ________.

• exposure

• population

• resources

• infrastructure

List the factors influencing the human impact of natural hazards.

• Geographical location, population density, and infrastructure

• Only geographical location

• Only population density

• Only infrastructure

The role of population density in influencing the impact of natural hazards is:

• It increases the impact by concentrating more people in vulnerable areas.

• It decreases the impact by spreading people out over a larger area.

• It has no effect on the impact of natural hazards.

• It only affects the impact in urban areas.

How do traditional methods of coping with hazards influence their impact?

• Traditional methods reduce the impact of hazards by enhancing preparedness and resilience.

• Traditional methods have no effect on the impact of hazards.

• Traditional methods increase the impact of hazards by causing confusion.

• Traditional methods are outdated and irrelevant in modern times.

The degree of accuracy in predicting the hazard is important because:

• it ensures better preparedness and response.

• it reduces the cost of insurance.

• it increases the frequency of hazards.

• it eliminates the need for emergency services.

The speed and effectiveness of relief services affect the impact of natural hazards by:

• Reducing the overall damage and aiding quicker recovery

• Having no significant effect on the outcome

• Increasing the severity of the impact

• Delaying the recovery process

How does a hazard turn into a disaster?

• When it causes significant damage and disruption

• When it is ignored by authorities

• When it is reported in the news

• When it occurs in a remote area

What is the importance of 'Depth of Focus' in determining the varied nature of the hazard?

• It helps in assessing the potential impact of the hazard.

• It determines the color of the hazard.

• It measures the speed of the hazard.

• It identifies the source of the hazard.
