Long Term Planning

• Occurs after the hazard event
• Looks back at the event and evaluates what could be done to reduce the impact of any future hazard events:
  • Was?emergency aid?distributed effectively
  • Are there areas which are at particular risk should they be protected more or buildings moved
  • Could?warning systems be improved
  • Are people educated about the risks and do they know what to do during the event to protect themselves
  • Can building codes and planning be improved to reduce the numbers of buildings which collapse
• Risk assessment?and?hazard mapping?are both part of the long term planning process

Risk Assessment

• Risk?is the probability that a hazard event will have harmful consequences
• The more vulnerable a population is the greater the risk that a hazard event will cause deaths, injuries, damage to buildings and impact the economy
• The number of deaths from earthquakes has increased
• Increasing populations and urban areas means that more people are living in areas at risk

Hazard Mapping and GIS

• Maps the areas where earthquakes are most likely to occur
• Enables planning of where important services and infrastructure should be located -?land use zoning
• Identifies?correlation?between risk and vulnerability

• In an earthquake, it is the collapsing buildings which cause the most injuries and deaths
• Earthquakes cannot be prevented, so reducing the damage to buildings is key to minimising the impacts. This can be achieved by:
  • Reducing the number of buildings in high risk areas
  • Building earthquake resistant buildings
• Large scale rebuilding is often required after an earthquake event
• Existing buildings and structures, such as bridges, can be?retrofitted?to make them safer in future events

Nepal - A Developing Country

• The Asian Development Bank provided?US$200 million?for rehabilitation
• A government task force was created to plan and deal with future earthquakes
• International donor meeting in June 2015 led to?US$4.4 billion?being pledged (only a small portion has currently been paid to Nepal)
• National Reconstruction Authority?was formed by the government. Part of the role is ensuring that funding distributed to help people rebuild their houses
• Disaster Management Act?passed by the government
• Improved building code with increased awareness of the code within communities
• Stonemason?training courses to ensure that new buildings are earthquake resistance
• Increased education and practice of earthquake drills

Japan - A Developed Country

• Building Back Better?- considers building codes, town planning and infrastructure
• New tsunami walls have been constructed 25-30m high
• A new?US$31 million?warning system launched in 2013
