Topic Summary: Natural Hazards Overview
Key Terms
- Natural hazard: Event threatening human life/property
- Natural disaster: Hazard that overwhelms coping capacity
- Risk: Hazard × Vulnerability ÷ Capacity to Cope
- Vulnerability: Susceptibility to harm — PEARL
- Resilience: Ability to absorb and recover
- Coping capacity: Resources to prepare, respond, recover
- DRR: Disaster Risk Reduction
- Sendai Framework: UN DRR agreement 2015–2030
Hazard Types
- Tectonic: Earthquakes, volcanoes, tsunamis — plate margins
- Atmospheric: Tropical storms, droughts, tornadoes
- Geomorphological: Floods, landslides, avalanches
- Biological: Pandemics, wildfires, pest swarms
Key Evidence
- Haiti 2010: 7.0 Mw → ~316,000 deaths (LIC)
- Christchurch 2011: 6.3 Mw → 185 deaths (HIC)
- Nepal 2015: 7.8 Mw → ~9,000 deaths (LIC)
- Chile 2010: 8.8 Mw → ~550 deaths (MIC)
- Climate disasters: +83% increase 2000–2019 vs 1980–1999
- Bangladesh: Bhola 1970 = 500,000 deaths; Sidr 2007 = 3,400 deaths (same hazard, better preparedness)
Exam Essentials
- PEARL: Poverty, Education, Access, Resilience, Location
- VERT: Vulnerability, Emergency response, Resilience, Type/magnitude
- Hazard ≠ Disaster: a hazard only becomes a disaster when it strikes a vulnerable population
- Magnitude alone does NOT determine deaths — development and preparedness matter more
- Hazard frequency rising; deaths falling in HICs; economic losses rising everywhere
- Sendai Framework 4 priorities: understand risk → strengthen governance → invest in resilience → enhance preparedness
