چکیده

Tehran is located in a seis mic prone zone in north central part of Iran a long Alpine-Himalayan orogenic belt. The city has experie nces many destructive earthquakes in its history and it is expected to be affected by strong earthquakes in future as well. Considering the geological setting o f this city, it is expected that any potential earthquake in Tehran may associate with some geological instabilities. In this paper, the potential geo-hazards that may asso ciate with earthquake in Tehran including ground motion amplification due to site effects, slope instabiliti es (landslides and rock-falls), liquefaction and land subsidence due to collapse of existing Qanats (undergr ound irrigation tunnels) will be introduced. In ad dition some measures to reduce the potential impacts of such hazards will be presented and discussed. Furthermore, the criteria for controlling the growth of the city towards hazard zone that have been reflected into the Master Plan of Tehran will be also introduced.
