Summary
Frequency, magnitude and energy of Indian earthquakes with magnitude greater than 5 has been studied. The Indian regions can be divided into three main seismically active regions, viz. 1. Delhi and Himalayan region, 2. Assam region and 3. Koyana region which includes southwest India. The relations between frequency-magnitude and energy-magnitude of earthquakes are shown in Fig. 3 and 4 respectively. Further a relationship, logN=p+q logE type has been established for frequency and energy of Indian earthquakes and the values of constantsp andq have been determined for all the three seismic regions. The results thus obtained are good and satisfactory.
