whats a natural hazard
physical process that has the potential to cause damage to human communities
whats a natural disaster?
the events following an actual occurence of a natural hazard
what factors impact vulnerability
physical (weather/season) economical (preparedness, mitigation - can be expensive) social and political (social structures are important for recovery)
where do these hazards usually occur: earthquake vs cyclone
earthquake - likley around tectonic plate boundaries (japan, indonesia, papua new guinae) cyclones - occur between 5 and 30 degrees latitude
what changes the impact of hazards
• speed of onset • magnitude • frequency • duration • temporal spacing • preparedness • predictability
