Hazard Adaptation + Mitigation Flashcards
Define hazard adaptation
Strategies designed to reduce the impacts of hazard events
Examples of hazard adaptation
High tech monitoring
Crisis mapping
Modelling hazard impacts
Public education
High tech monitoring definition
Monitoring systems for hazards
What does High tech monitoring consist of
GIS maps, early warning systems, satellite communications and mobile phones
Advantages of high tech monitoring
Helps to manage hazards effectively because it assists with evacuation plans and understanding where has been affected
What does Crisis mapping consist of
Uses crowd sourced information as well as satellite imagery, other maps and statistical modes accurately map areas struck by disaster
Aid agencies are beginning to use crisis maolung
How does Modelling hazard impact work
Computer models allow scientists to predict the impacts of hazard severity on communications
Information is fed into computer systems which then models the effect of a disaster
It allows comparing the effects of different scenarios
Public education advantages
Good education and better public awareness can help reduce vulnerability and prevent hazards from becoming disasters
Public education helps people to understand what they can do to protect themselves throughout the hazard event
Public education example
Japaneses children practise earthquake drills 4 times a year
Define hazard mitigation
Strategies meant to avoid, delay or prevent hazard events
Examples of hazard mitigation
Land use zoning
Diverting lava flows
GIS mapping
Hazard resistant buildings
Land use zoning definition
A process by which local government planners regulate how land in a community may be used
Land use zoning example
Mount taranaki in New Zealand divides zone based on likely type and level of damage from eruption.
At a high risk from volcanic eruptions and tsunamis will cause settlements to be limited, communities may be resettled, development which provide natural protection is limited
Land use zoning disadvantage
Rare to find land use zoning in developing countries
Diverting lava flows definition
Building barriers and digging channels to try to divert the flows into a safer direction
