1.5B Hazard profiles

• Hazards with the following characteristics present the highest risk:

  • high magnitude, low frequency events - these are the least 'expected' as, by definition, they are unlikely to have occurred in living memory
  • rapid onset events with low spatial predictability - they could occur in numerous places and without warning
  • regional areal extent - affecting large numbers of people in a wide range of locations
• Hazard profile

  
• Spearmans' rank equation = $P =$$1 − 6 ∑ 𝑑^2i/ 𝑛 ( 𝑛^2 − 1 )$
