What factors affect the impacts of earthquakes?
The quality and stability of the buildings in the area
Proximity to plate margin and margin type
More frequent and powerful along the Pacific Ring of Fire
Combination with other hazards, e.g. volcanoes?
How deep the focus of the earthquake is
Deep = less severe
Shallow = more severe
Geology of the area
Saturated soil
Liquifaction
Solid bedrock
Population density
Density of buildings - high- or low-rise
High density likely to lead to high rates of death and injury
High or low income countries - level of economic development
HICs will likely have better ability to predict, monitor and respond to earthquakes and other hazards
Time of year and weather conditions
May affect people's ability to survive
Cold or wet weather
Preparedness and access
Training and resources of resources of rescue teams
Accessibility to disaster zones
Landslides / mass movement
Proximity to epicentre
Strength of the quake on the Richter scale, the higher it is the worse the impacts will be
