Document Summary

Fundamental concepts of understanding natural processes as hazards. Hazards linked to each other and environment. Population growth and socio-economic changes increase risk fro natural hazards. Damage and loss of life from natural hazards can be reduced. Determine the risk: risk = ph x sh (ph = probability of hazard happening, sh = severity of consequence if hazard occurs) Determine ways to reduce ph and/or sh. Do a cost-benefit analysis: cost not just money, but also social or environmental impact. An earthquake is a vibration of the earth produced by rapid: energy released radiates in all directions from the focus, energy in wave form called seismic waves, can record with seismographs, involves the rapid displacement of rocks. Note many rivers occur along faults: often build dams on these rivers, high walls of valley. Seismometer: measures distances seismic waves, if we only had one type of body wave. One side slips down relative to the other.
