Earthquake source parameters provide information about the source properties of individual shocks, which can serve as an important basis for generalization about, and synthesis of, strong ground motion. Source function is also one of the most important contributors to seismic hazard analysis because it provides information about the seismic energy released during an earthquake. Recent advances in seismic source theory have improved our understanding of body wave spectral characteristics and physical properties of the source such as seismic moment, stress drop, and the area of rupture. Brune (1970) developed a model to calculate source parameters using near and...
