      - Prepare
      - Act
- - - - Using air drops, where water and fire-retardant chemicals are released from aircraft onto the wildfire. So another area will not be affected.
      - Removing dead leaves and branched from areas at risk from wildfires and controlled burns take place in order to remove dead plant material before any fires start.
    - - Lightning striking trees may cause a fire to start, but most most of these are small and soon die out.
      - Volcanic eruptions emit red-hot lava and ash.
      - Spontaneous heating is where material becomes heated to the point at which it will catch fire without a spark being present.
    - - Accidents are to blame for starting many wildfires.
      - Broken bottles can act as a magnifying glass.
      - Slash and burn is a method farmers use to clear land to grow crops.
- - - - Tourism
      - Mineral extraction
      - Geothermal energy
      - Raw material
      - Fertile soils
      - Example: Geothermal power is widely used in places such as New Zealand, Hawaii and the volcanic island of Iceland, where it provides 70% of energy needs.
    - - Early warming systems
      - Engineering
      - Planning
    - - Restricting access to the area
      - Evacuating the area danger area
      - Building rock walls to divert lava away from villages.
      - Dropping water to cool the lava in order to slowing it down
  - - - Primary effects- Builds collapse, roads crack, bridges collapse, glass shatters, gas pipes break, electricity pylons fall, water pipes break
        Secondary effects- Fires, explosions, floods, homelessness, tsunamis, diseases, landslides, businesses forced to close, cost of insurance claims, unemployment
