GCSE Factors affecting hazards

Natural factors
such as rock type, shape of coastline, relief etc. can affect how much damage is done by a hazard
The size of the event massively affects the impact it has. e.g hurricane of magnitude 5 on the Saffir Simpson scale will have more impact than that which has a magnitude 3
This is how often the hazard occurs
Population density
The number of people in an area and where they are. Generally, the greater the number of people in an area, the greater the potential for disaster.
Level of Development
How wealthy a place is - determines how much money is available to PREPARE the buildings and people to cope with it, and also determines how the country RESPONDS after the event.
Planning Laws
Laws that prevent building in hazardous locations, along a low coastline at risk from storm surges in a hurricane for example.
What things are put in place in advance of hazards to limit damage, such as making buildings earthquake proof or life safe
Organisations such as the UN that can act quickly to help people after a disaster, includes a well-equipped army or fire service and experts to coordinate a response in both the short and long term.
developing peoples knowledge so that they know what to do in a disaster
Time of event
When the event occurs - determines what people are doing when the hazard occurs and how they respond e.g. is it nighttime when people are asleep?
Location of event
Where the event occurs - includes things like earthquake depth
