In such cases the most commonly adopted seismic source is the area source zone. The formation of seismic area source zone is subjective for regions such as south India and hence zonefree techniques to probabilistic hazard analysis have been carried out in the past. The zonefree technique specifically the kernel technique is still new and has been applied to specific sites in south India such as Chennai and Kanchipuram. In this study the fixed and adaptive kernel techniques have been applied to the whole of south India to obtain the hazard value. The most influencing parameter affecting the kernel technique has been varied in two ways - the bandwidth parameters determined for the whole earthquake catalogue of south India and the other by determining the bandwidth parameters for the earthquakes lying in an influence area of 300 km radius around a particular site. It was observed that the adaptive kernel technique yielded slightly higher hazard values in regions of high seismic activity and lower values in regions of low seismic activity. However both the techniques yielded similar results in regions of spatial uniform seismicity. A significant difference was observed in the uniform hazard spectra obtained for specific sites in south India when the bandwidth parameters were estimated considering whole of south India (regional) and an influence area of 300 km radius (local).
