GGR378 Lecture Notes (January, 7, 2013)
5 Fundamental Concepts
1. Understanding hazards through scientific analysis
a. Mapping, modeling, monitoring, hazard assessment, measuring magnitude,
prediction/forecasting
2. Evaluating Risk
a. Hazard: the actual, physical event (ex: volcanic eruption)
b. Risk: probabilities and impacts of hazardous event
c. Vulnerability: characteristic of people and of communities that render them more or
less vulnerable
Impacts of Hazards
a) Primary: direct impacts of events
b) Secondary: one-time removed, indirect result but would not have occurred if event didn’t
happen (ex: fire caused by earthquakes)
c) Tertiary: one-more time removed, another indirect long-term impact (ex: Hurricane Katrina
causing permanent changes to landscape infrastructure collapse)
3. Hazards linked to each other and environment where they happen
a. Cause and effect, triggers, complex of cascading events (something happens, triggers
another event, that trigger then triggers another, so on)
4. Population growth + socio-economic changes = increasing risk of hazards
a. Role of environmental change, human activities, population distribution and
anthropogenic vs. natural disasters
5. Damages from natural disasters can be reduced
