Document Summary

Defining and mitigating exposure of natural hazards on humans: managing risks, reducing human impact that affects the severity of hazard. Risk analysis and risk management (look at week 5) Risk: the overlap of exposure (of people/property), vulnerability (people and infrastructure), and hazard. Risk analysis: understand hazard, determine risk. Asses seismic risk: locate and determine faults in the area. Moved within 111,600 years= active, within last 2. 6 million year = potentially active, later than 2. 6 million years = inactive. Inactive fault: law of superposition, law of cross-cutting relationship: study history of earthquakes in the area. Constructing probability and earthquake-hazard maps: determine geologic and geographic relationships in that area. Map out the different rock and soils, clay and sand that are prone to liquefaction, coastal areas prone to tsunamis, cliffs and hills. Relative amplification: determine the human interaction with the hazard in that area. No people or property = no risk. Risk management: apply land use planning and zoning.
