multiple hazard zones

• multiple hazard zone definition

  an area at risk from multiple hazards and is vulnerable
• hydrometerological hazards

  natural hazards caused by climate processes
• phillipeans : example of multiple hazard zone

  1. convergent plate boundary (volcano + earthquake risk)
  2. faces pacific ocean (tsunami risk)
  3. tropical monsoon climate
  4. common landslides
• phillipeans : why it’s vulnerable

  1. growing population, urbanisation and poverty
  2. lower middle income country
  3. many live in coastal areas
  4. 25% live in poverty
• challenges of multiple hazards

  1. one hazard event can cause another
  2. hazards happening in short spaces of time drain resources
• reasons for why the world is becoming more hazardous

  1. improvments in monitoring and recording events = increasing amounts of events recorded
  2. improvements in communication
  3. increased population = more ppl live in hazardous areas
  4. increase is occupied living space = flood risks
• current hazard trends

  1. a country’s economic levels impacts the amount of people affected
  2. number of people killed by disasters globally is falling
  3. financial cost of disasters is rising. 1990: $20billion per year 2000-2010: $100billion
• data accuracy and vulnerability

  1. data recieved about frequency’s and impacts may be incomplete or inaccurate
  2. methods vary in data collection
  3. difficult to gather data from remote areas
• hazard profile

  a diagram that shows the main tectonic characteristics of different hazards. it can show multiple different hazards. They help governments + organisations create disaster plans
• physical reasons for why some countries are more vulnerable to tectonic hazards

  1. geographical features
  2. plate boundaries
  3. physical environment eg slopes + lowlands = floods
• economic reasons for why some countries are more vulnerable to impacts of tectonic hazards

  1. ability to prepare and respond
  2. durable infranstucture, technolog, insurance
• social reasons why some countries are more vulnerable to impacts of tectonic hazards

  1. education levels
  2. gender roles
  3. high population density
