Methods of tectonic hazard mitigation Flashcards
Volcanic eruption
how can it mitigated
Barriers diverting lava flows away from Mt Etna in Sicily in 1991
7 billion tones of water sprayed onto approaching lahars to cool them down and solidify them in 1973c in Iceland
Volcanic eruption how can you mitigate vulnerability
Monitoring and predicting
Evacuation plans
Warning systems
Volcanic eruption how can you monitor the loss
Rescue and relief efforts
aid from governments and NGOs to help with rescues and providing necessities post event
Earthquakes how can you modify the event
Not yet possible
Earthquakes how can you modify vulnerability
Planning codes and restrictions
- building codes requiring aseismic (earthquake-resistant) buildings (in Japan)
Tsunamis how can you modify the event
Costal defences and hard engineering, for example Japan has built a 400km chain of concrete sea walls in some places being 12m heigh
Tsunamis how can you modify human vulnerability
Education on risks and how to stay safe
Clear marked evacuation routes
Warning and prediction systems
