- Modification of event, vulnerability and loss (hazard management)
- Park's Model - Preparation (pre-disaster), response (1-7 days) Reconstruction (1-12 months) Mitigation (several years)
- Event (used to reduce extent or magnitude)
- GIS Mapping
- predicting events using high technology.
- used in most places
- Diverting lava flows
- Italy, Mount Etna 1983
- channels, barriers, water cooling systems.
- keeps people out of danger, low cost
- only works for low VEI basaltic lava, not extremely dangerous anyway
- aseismic buildings
- Japan, 75% of buildings built with events in mind
- cross-bracing, counter weights, deep foundations, "quake-proof" housing.
- can prevent collapse, protects people and property
- high cost for tall structures, old or low-income homes are rarely protected.
- Land use zoning
- New Zealand, Mount Tallania
- preventing building on low-lying coasts or close to volcanoes.
- Low cost, keeps people safe
- prevents coastal tourism, requires strict planning.
- Tsunami defences
- Sea walls, breakwaters.
- expensive, may be exceeded anyway, ugly
- reduces damage massively, provides security sense.
- GIS Mapping
- Vulnerability - increasing resilience of a community
- Community preparedness
- earthquake kits (boxes of essentials). Educating in schools and communities
- low cost (by IGO's), can save lives
- doesn't prevent property damage, harder to implement in cut-off areas
- High-tech scientific monitoring
- predicting eruptions and events (on other mind map)
- warnings and evacuations save lives
- costly, may suffer 'cry wolf syndrome'.
- adaptation
- moving out of harms way and relocating
- would save lives and property
- high populations prevent this, disrupts traditions
- Community preparedness
- Loss
- short term emergency aid
- 70 rescuers and 2 search dogs to Tohoku, 2011.
- reduces death toll by saving lives
- physical difficulty in isolated areas, emergency services poorly equipped in developing
- long term aid
- reconstruction plans (Japan, new buildings quake-proof)
- can build in resilience through better construction methods
- very expensive, needs are forgotten by media after disaster hit
- Insurance
- compensation for loss
- allows people to recover economically to pay for re-construction
- low-income countries may not have this, does not save lives
- short term emergency aid
