Proceedings of the "WORKSHOP ON MICROZONATION" address microzonation studies carried out in India. Mapping the seismic hazard at local scales to incorporate the effects of local ground conditions is the essence of microzonation. Seismic microzonation is one of the tools, which is considered to be very important to help in mitigating future earthquake disaster. The first international conference on this subject was held as early as in 1972 and several such conferences have been held in different parts of the world since then. Microzonation is similar to the macro level hazard evaluation but requires more rigorous inputs about the site specific geological, geophysical, geotechnical, seismotectonic, ground response to earthquake motions and their effects on the safety of the constructions, taking into consideration the design aspects of buildings, ground conditions which would enhance the earthquake effects like soil amplification, liquefaction of soils etc. and safe construction practices to avoid the losses from the future earthquakes. The workshop attempts to address all the issues both from conventional and well as probabilistic approaches considering local site effects. Ever since the pilot study of microzonation of Jabalpur, in India various techniques of hazard assessment that would eventually lead to microzonation are being practiced in India. Under the DST's Seismicity Programme, there have been several initiatives to do microzonation of major cities. These efforts are in various stages of progress, for the cities of Delhi, Dehradun, Bangalore, Ahmedabad, Sikkim, and Gauwhati. The procedures for microzonation involve various steps and analysis of a large amount of multidisciplinary data. It also requires many specialists to work together. The 2-day workshop on microzonation, at IISc, Bangalore (26th and 27th June 2007) provided a forum for geologists, seismologists, geotechnical engineers and structural engineers to discuss the concepts and methodologies for microzonation studies in India. Further, this workshop provided a forum for dissemination of the knowledge in this area along with the results of the ongoing projects. Workshop also highlights on the techniques and procedures followed elsewhere and how these can be used in the context of studies in India further to develop a set of standard procedures that may be followed by all those who are involved in these efforts.
