Chennai, the capital City of Tamil Nadu covers an area of 170.98 Sq, km is the fourth largest Metropolitan City in India and is experiencing rapid growth in population. An understanding of Seismic Hazard is necessary for Chennai city where even moderate earthquakes have high hazard potential in larger areas due to the dense population and efficient transmission of wave energy. A study on Seismic Hazard Analysis for Chennai city carried out based on deterministic approach using remote sensing and GIS techniques. The seismic potential sources have been identified based on satellite remote sensing data integrated with past earthquake epicenters and limited field checks. Shortest distance from the each seismic source to the Chennai City measured by Arc-Info Measuring tool and the Peak Ground Acceleration (PGA) at bed rock level is calculated for the identified sources with their maximum credible earthquake events using available attenuation relationship formula applicable to Peninsular India. To calculate hazard in the area, a grid is formed dividing each degree of latitude and longitude in to three parts. Arc-GIS layout tool is used to perform the grid analysis. The seismic hazard of Chennai city is expressed in the form of iso-acceleration contours. The estimated maximum PGA from the four seismic source zones was in the range of 0.145g to 0.078g. The contour of PGA values generated by the different sources indicates the seismic source in the eastern part of the study area is to be have more attention for further research. © 2011 CAFET-INNOVA technical society.
