Abstract
Dehradun is very old city and also rapidly growing urban area located in valley at foothills of Garhwal Himalayas. Dehradun city and adjoining region in western Himalayas is a is a very active seismic region of Himalayan belt , stretching from Pamir - Hindukush to Arkans in Burma.According to seismic zoning map of India , Dehradun city lies in Zone 4 and expected MSK intensity 8 .Dehradun city is located in the vicinity of twenty four independent seismic source zones which in reality are active faults. This creates uncertainties in size , location and the rate of recurrence of earthquakes. Probabilistic seismic hazard analysis provides a framework in which these uncertainties can be identified , quantified and combined in a rational manner to provide a more complete picture of the seismic hazard . This study presents a PSHA of the Dehradun city using the attenuation relationship given by Cornell et al (1979) in order to determinate various levels of earthquake-caused ground motion that will be exceeded in a given future time period.
