      • Modification measures
      • Mitigation measures
      • Preparedness measures
      • Respond and recover
      • Economic offset measures
      • Redevelopment
    • Factors that effect hazard management
      • Geographical scale of hazard
      • Magnitude of hazard
      • Onset speed/ warning of hazard

      • Jan 1973
      • 5300 residents of Heimaey Island evacuated
      • Sea water sprayed onto advancing lava flows for 6 months
      • 43 pumps and 30km of pipe used to deliver 1 cubic meters of sea water per second
      • 6 million cubic meters of water in total
