Document Summary
What nature presents to us (natural disasters) Speed of tectonic movements, location of faults, locked or aseismic creep, quality of soil (liquefaction, water saturated sediment) We cannot do anything about it, but move away. Construction of quality buildings and structures, eq resistant designs, personal preparedness. This is where we can significantly reduce risk. Reduced vulnerability by having pipelines built on fixed, anchored tilts, so that pipelines wouldn"t break when eq hit. Peak ground acceleration measured in % of g; g = gravitational acceleration everything >1g: weightlessness the maximum ground acceleration that occurred during earthquake shaking at a location. Soil type may further cause liquefaction or landslides. Emergency operations; hospitals, fire stations, police stations. Schools, nursing homes, grocery stores, banks, governments. Lifelines: roads, electric power, power plants, drinking water, phone-internet. However, could also boost an economy from rebuilding. Having shear walls and bolting frame to foundation to reduce structural damage in building.
