The 20 questions
-
Which of these is an atmospheric natural hazard?
- Earthquake caused by movement of rock along a fault line deep in the crust
- Tropical storm
- Lahar formed when volcanic debris mixes with water on a steep slope
- Landslide triggered when saturated slopes give way under gravity
-
In the Park model of human response to hazards, which response involves accepting that an event cannot be avoided or controlled?
- Fatalism
- Risk sharing, where losses are spread across many people through insurance schemes
- Mitigation, where engineering works are built to reduce the physical impact of the hazard
- Prediction, where forecasts are used to warn people before an event arrives
-
What does hazard magnitude measure?
- How often events of a particular type occur in a region over a set period of time
- The number of people who are affected by an event in the area around it
- The total money spent by governments and aid agencies on recovery after the event
- The size or energy released by a single hazard event
-
Which term refers to how often a hazard event of a given size occurs over time?
- Distribution, which describes where across the landscape events are located
- Frequency
- Magnitude, which describes the size or energy of a single event rather than how often it happens
- Hazard perception, which describes how people understand and feel about the risk
-
Which stage of the Hazard Management Cycle comes immediately after a disaster?
- Response
- Prevention, which aims to stop certain hazards from happening at all in the first place
- Mitigation, which involves long-term actions to lessen the impact of future events on communities
- Preparedness, which involves planning and training so that communities are ready before an event
-
A wealthy city and a poor city both experience an earthquake of the same magnitude, but the poorer city suffers far more deaths. Which explanation best fits the concept of vulnerability?
- Wealthy cities experience no secondary hazards at all, such as fires, landslides or disease after the shaking
- The earthquake magnitude was greater in the poorer city than it was recorded to be in the wealthier city
- Poorer cities have fewer earthquakes each year, so their residents are less prepared for the events that do occur
- Lower development reduces the capacity to resist, absorb and recover from the hazard
-
Which of these is a hydrological hazard?
- Earthquake, a sudden release of energy from the lithosphere that sends shockwaves through the ground
- Flood
- Heatwave, a prolonged period of unusually high temperature in an area affecting health and water supply
- Tornado, a rapidly rotating column of air that extends from a storm cloud down to the ground
-
Which factor is most likely to lower a population's perception of a hazard?
- A long period without a damaging event, leading people to underestimate the risk
- A recent severe event that is still fresh in people's memory and frequently discussed locally
- Frequent official warnings issued through the media in the days leading up to the event
- Media coverage of disasters in other countries that leads people to compare their own risk
-
Which term describes the consequences of a hazard event for people, property and environments?
- Adjustment, the ways in which people change their behaviour and lifestyles to live with a hazard
- Frequency, how often events of a given type take place in a particular area over time
- Impact
- Magnitude, the size of the event measured in energy released by the physical process itself
-
Which human response involves sharing the financial losses of a hazard across many people, for example through insurance?
- Prediction, the use of monitoring and forecasting to anticipate when a hazard is likely to strike
- Adjustment, changing how people live and build so they can tolerate hazards when they occur
- Fatalism, the acceptance that hazards are beyond human control and that little can be done about them
- Risk sharing
-
Mitigation differs from adjustment because mitigation:
- Accepts the hazard as unavoidable and changes only personal behaviour and daily routines
- Aims to reduce the severity of a hazard's impacts through engineering or planning measures
- Involves no action before the event occurs, focusing entirely on the recovery and rebuilding phase
- Relies mainly on insurance payments made to households after an event has already occurred
-
Which statement best evaluates the view that natural hazards are purely physical events?
- Hazards depend only on the physical event, so human conditions have no effect at all on the losses that people suffer
- Hazards affect only developing countries and are unrelated to economic conditions, so wealth makes no difference to outcomes
- Hazards are always fully predictable in every location, so human factors such as planning and warning systems do not matter
- Hazards are shaped by human vulnerability, so impacts depend on social and economic conditions as well as the physical event
-
A flood has a recurrence interval of 100 years. What is the approximate probability that it occurs in any given year?
- 0.1 per cent, which would imply that such a flood occurs only once in a thousand years
- 1 per cent
- 50 per cent, which would imply that the flood is as likely to occur as not in any single year
- 10 per cent, which would imply that a flood of this size happens roughly once every ten years
-
Which of these is a geophysical hazard?
- Drought, a prolonged shortage of rainfall that reduces soil moisture and water supplies in an area
- Flood, which occurs when rivers overflow their banks after prolonged or intense rainfall
- Tropical storm, which forms over warm oceans and brings strong winds and heavy rainfall to coasts
- Volcanic eruption
-
A hazard of high magnitude occurs in an unpopulated region. What is the most likely consequence for people?
- Immediate evacuation of the surrounding region as officials respond to the event across the wider area
- Large economic losses in a nearby major city that depends on the region for its supply of goods
- A very high death toll among local residents who have no warning and cannot be evacuated in time
- Few human impacts, although environmental change may still occur
-
What is the main purpose of the Hazard Management Cycle?
- To show how management of a hazard moves through stages before, during and after events
- To list only the physical causes of hazards without considering how people respond to them
- To predict the exact time and place of the next hazard event so that people can be warned in advance
- To calculate the insurance premiums that households in hazard-prone areas must pay each year
-
Which factor would most increase the impact of a hazard event on a community, other things being equal?
- Sparse settlement on stable high ground with strong and well-enforced building regulations
- Dense settlement on a floodplain with weak building standards
- Widespread use of earthquake-resistant design in new buildings and retrofitting of older structures
- Strong early warning and evacuation plans that are regularly rehearsed by the local community
-
Which response to a hazard would be classed as adjustment?
- Staying in place and ignoring official warnings because the community has always coped in the past
- Raising homes on stilts in a flood-prone area so that floodwater can pass beneath them
- Insuring property against flood loss so that financial losses are shared across a large pool of policyholders
- Building a large barrier across a river to hold back floodwater from reaching the surrounding towns
-
Why do hazard impacts often differ between developed and developing countries?
- Hazard magnitude is determined by the income level of the country in which the event takes place
- Richer countries may suffer more economic damage in absolute terms, while poorer countries often have higher death rates
- Development makes hazard events more frequent in all countries, so richer nations experience more events than poorer ones
- Poorer countries never experience any economic damage from hazards because their economies are too small to be affected
-
Which term describes the spatial pattern of where a hazard occurs?
- Distribution
- Magnitude, which describes the size of a hazard event rather than where events happen across the landscape
- Frequency, which describes how often hazard events of a given type take place in an area over time
- Predictability, which describes how well events can be forecast in advance before they actually happen
