DISLOCATION AND STRONG GROUND MOTION ZONINGUNDER SCENARIO FAULTS FOR LIFELINES

摘要

Present paper proposes a seismic hazard map in Tehran City to evaluate the seismic safety of gas supplysystems extended whole in the city. First, the seismo-tectonic feature in Tehran area is investigated andscenario active faults that cause severe earthquakes are specified giving fault parameters. Based on thefault analysis, synthetic strong ground motions are estimated on the surface ground by using convolutionmethod for element earthquakes and non-linear amplification factors. Then surface fault dislocation isestimated by using elastic dislocation theory. Furthermore, the potential of liquefaction and land slide isinvolved in the hazard map.
