Hazard in Cities (Case Study in Tehran & California) Earthquake

The active faults upon which Tehran megacity was developed must be considered in urban planning. Insufficient preciseness and completenessof the previous fault maps and lack of required technical documentation for existing regulations on building construction in fault zones, prompted the Tehran disaster mitigation and management organization (TDMMO) to scrutinize existing fault map and produce more accurate one and in the same time devise new regulations. To this end, the Alquist-Priolo (AP) Earthquake Fault Zoning Act and sets of Fault Evaluation Reports and Fault Investigation Reports of California were reviewed and necessary conclusions regarding eventual adoption of similar measures for Tehran were drawn.
