- Modifying Event
- local-scale success with slowing and diverting lava flows from Etna
- Earth barriers, large concrete blocks dropped into lava flow, channels dug to divert lava flow
- local-scale success with slowing and diverting lava flows from Etna
- Modifying Vulnerability
- Monitoring plays a big role - CFCRV is basis for decision making such as evacuation orders.
- long term analysis of eruption patterns
- international comparisons
- constant monitoring (seismometers, tilt meters, infra-red, weekly bulletins)
- well established alert level sequence
- closure of airports and air space when threatened by ash
- research into the most effective building design to resist ash fall
- Monitoring plays a big role - CFCRV is basis for decision making such as evacuation orders.
- Modifying Loss
- Well practiced in dealing with volcanic hazards.
- compensate communities and individuals
- swift evacuation processes
- well trained fire and military services
- Modifying Event
- Indonesia
- Modifying Event
- Very little could be done due to minimal tech and preparation
- Modifying Vulnerability
- CVGHM est. 1920 has observatories across Indonesia
- Technology was and has been limited
- Funding for programme was limited as weak economy
- Also political divergence and tension after WW2 made volcanic monitoring minor priority
- 60 volcanoes monitored
- Works closely with local Govs on mitigation strategies
- National Agency for Disaster Management
- Settlement relocation
- often contested
- CVGHM est. 1920 has observatories across Indonesia
- Modifying Loss
- LIDC so resources it can deploy are minimal
- Some well trained emergency services and military
- Temporary shelters in safe zones are available
- Authorities have cleared river channels of volcanic material and other debris to reduce flooding and lahars
- Some material has commercial value
- Modifying Event
- Italy
