- Factors affecting earthquake death toll
- How developed the country is
- Development of structurally sound buildings
- Population density
- Other natural disasters caused by the earthquake
- Tsunami
- Landslide
- Liquefaction
- Volcanic eruption
- Avalanche
- Density of population
- The closer people live, the more people a collapsing building will impact
- How structurally sound the buildings are
- Earthquake resistant buildings
- Developed
- Damper in roof
- Shock absorbers
- Strong steel frame
- Very deep foundations
- Strong double glazed windows
- Cross bracing stops floors collapsing
- Developing
- Lightweight thatch roof
- Walls made of mud and straw packed between wooden slats
- Simple steel rod foundations
- Concrete ring ties the walls to the foundations
- Cross braced wood or bamboo frames
- Developed
- Earthquake resistant buildings
- Epicentre/ Focus
- Epicentre location
- How close it is to civilisation
- Depth of focus
- If closer to surface, will be felt more
- Epicentre location
- Country's wealth
- Development of structurally sound buildings
- Plate boundary the earthquake is on
- Constructive e.g.Mid-Atlantic ridge
- Less violent earthquakes
- Less violent eruptions
- Destructive e.g.Andes
- Violent earthquake
- Violent eruptions
- Conservative e.g.San Andreas fault
- Violent earthquake
- Rare eruptions
- Collision e.g.Himalayas
- Violent earthquake
- Rare eruptions
- Constructive e.g.Mid-Atlantic ridge
- Magnitude of earthquake
- Greater magnitude - more destructive
- How developed the country is
