11. DEVELOPMENT OF MODELS FOR RATING SEISMIC ACTIVITIES USING RADIATED ENERGY OF EARTHQUAKES

ABSTRACT

Seismic activity evaluation is usually carried out using the Gutenberg-Richter’s (G-R) relation. This relation is defective because it does not include area of the region involved, thereby making a small but active region to be underrated. Secondly it gives the rate of seismicity of a region in terms of the total number, N, of earthquakes irrespective of magnitudes. This makes regions with few but great earthquakes to be underestimated since energy due to magnitude m...
