How can tectonic hazards be managed? Flashcards
What are the three ways tectonic hazards can be managed?
- modify the event
- modify the vulnerability
- modify the loss
Two strategies for modifying the event?
- lava diversion/draining
2. coastal environment strategies
Description of the lava diversion?
diverting lava flows away from people and buildings by either use of explosives or spraying the lava with sea water
example of when lava diversion has been used?
Mount Etna eruption in May 1983, only a partial success as only stopped it for a little bit
Description of coastal environment strategies?
aims to modify the coastal environment to reduce tsunami risk. can be achieved by mangroves and sea walls which act as buffers
Why is it impossible to modify the event in the case of earthquakes ?
earthquakes cannot be reliably predicted and once they start they cannot be stopped
Four strategies that modify the vulnerability?
- predicition/ forcasting
- land use zoning
- building design
- community prepardness
Two strategies which modify the loss?
- Aid
2. Insurance
