For this purpose, earthquake events catalogue was prepared for various earthquakes that occurred from year 1984 to 2003 in Peninsular India (PI). The data was obtained from Seismotectonic Atlas of India (GSI). Sizes of these earthquakes for most of the sites are defined in terms of Surface wave Magnitude (Ms) and the Body wave Magnitude (mb). These values of magnitude were converted into uniform moment magnitude (Mw). By using moment magnitude and hypocentral radius, PGA values were computed using Iyengar & Raghukanth’s attenuation relationships. From the study it is found that large portions of PI regions are over estimated. In this regard, it is recommended to study macro seismotectonics of Indian plate before taking up microzonation in a big way.
