Document Summary
Geology: earth, the materials of which it is made, the structure of those materials, the processes acting upon them, how these have changed over time. Environmental geology: concerned with the interactions between humans and the geologic environment, applies geologic knowledge to identify, remediate, minimize and possible prevent human caused environmental problems from occuring, defines and mitigates exposure of natural hazards on humans. Annual disaster statistical review 2006-2015: 376 natural disasters/year, 69,827 deaths/year, 224 million people affected/year, 137. 5 billion us$ damages/year, number of disasters is rising from 1960-2010. Factors that increase impact of natural hazard events: human population growth (overpopulation, demand for resources rise. Increase in the level of affluence: poor land-use practices, building on a flood plain or low coastal land. Natural hazards: natural processes or events with the potential to threaten human life or property, natural hazards of geologic origin include, earthquakes, volcanic eruptions, landslides, tsunamis and floods.
