Factors Affecting Earthquake Damage
Strength
+Richter scale = +strength = +damage
Number of aftershocks
+Aftershocks = +Damage
Population and Building Density
+Population/building = +more damage
Time of day
Daytime/Rush hour = +people in industrial areas = +damage
Secondary Hazards
Mudslides
Tsunamis
Fire
Contaminated water
Diseases
Hunger
Hypothermia
Types of rocks and sediment
Loose materials = liquefaction = -resistance = +damage
Types of building
Better building = more resistant to earthquake
Economic development
MEDCs = more prepared = less effected
Depth
Shallow-focus = greater damage
Distance from Epicentre
Closer to the epicentre = more damage
