Lecture 1 ggr378
Five Fundamental Concepts*
1.Hazards can be understood through scientific analysis.
Scientific understanding of Earth processes
* Based on Keller et al., 2012, Natural Hazards
2.An understanding of hazardous processes is vital to evaluating risk.
Hazard, risk, and vulnerability
Risk involves probability – when, where, and potential for exposure and impacts; costs
Vulnerability is a property of an individual, a property, or a population
Social and economic factors affect risk and vulnerability
Impacts – primary, secondary, tertiary
3.Hazards are commonly linked to each other and to the environment in which they occur.
Complex and cascading events
4.Population growth and socio-economic changes are increasing the risk from natural hazards.
Role of environmental change
Role of human activities
Role of population distribution
Anthropogenic vs. natural disasters
Damage and loss of life from natural disasters can be reduced.
Integrated approach to disaster management
Disaster planning and preparedness

Role of Science in Natural Disaster Management
Refers to a particular level of impact resulting from a hazardous event
“A [disaster is a] serious disruption of the functioning of a community or a society causing
widespread human, material, economic, or environmental losses which exceed the ability of the
affected community or society to cope using its own resources.”
