A probabillstic model, which makes use of Modified Mercalli Intensity data, has been developed for evaluating seismic risk in Northern India, This model predicts the probability of exceedance of any specifled earthquake ground motion amplitude (peak amplitudes or spectra) from all the earthquakes expected during some selected future perlod in the region around the site of interest and does not use only a single design earthquake. All the physical parameters like seismicity In varlous seismic source zones and the attenuation from source to site, which have inherent uncertainties in their description, have been treated probabillstically. Thus the randomness in the physical processes and the lack of knowledge about them have been accounted for in this presentation. An intensity attenuation model, which can give the probability of occurrence of any intensity at any epicentral distance has been developed first. This provides input for the risk model,
