The use of theoretical seismograms to model teleseismically recorded body waves has significantly enhanced the ability of seismologists to describe the dynamics of the rupture process in earthquakes. The purpose of this chapter is to demonstrate that even for a shallow earthquake, broadband data can be used to great advantage in interpreting the dynamics of the rupture process. As one example of such an analysis, this chapter describes the modeling of broadband body waves from the 2342:37.85 G.m.t. May 2, 1983, Coalinga earthquake (m{sub b} = 6.2, M{sub s} = 6.7). The teleseismically inferred source parameters are derived entirely from properties of the body waves. The resulting rupture history provides an independent complement to aftershock and strong-motion data for understanding this earthquake.
