Document Summary
Assessing seismic risk of an area: determine the geologic/geographic feature in the area. Map out locations of rock, sand soils, clay soils, etc. Map out zones of clay and sand that are prone to liquefaction. Shore lines of oceans and lakes: determine the potential human interactions with the hazard in the area. Particular attention to proximity of people to high-risk zones. Reduce sh: apply land-use planning and zoning, apply stringent building codes, set up warning systems and emergency response plans, try predicting quakes. Use high-risk areas for low-population use parks, golf-courses, etc) In particular, don"t allow buildings in areas of soft soul of soils that might liquefy. Good materials: wood, steel, reinforced concrete (all flexible) Bad materials: heavy masonry, stucco, adobe, unreinforced concrete (all rigid) Ex: 2 earthquakes in 88-89 similar in mag, one in loma prieta and one in.
