Abstract
This chapter is an introduction of methods employed in seismology to image seismic sources. We start with a review of classic teleseismic body-wave modeling for source parameters (seismic moment, faulting geometry, source duration) with a spatial point-source assumption and using efficient fundamental-fault responses. Next we discuss point-source moment-tensor inversion with a fixed time history, a variable time history, and a time-dependent moment tensor. We then discuss a spectral approach to use surface-wave observations to constrain source parameters (again for point sources). We close with a review of two approaches for extracting information on the rupture and finiteness of larger events. The first is an iterative pulse stripping approach that helps identify subevents in a larger composite rupture. The second is finite-fault modeling – in which the rupture propagation and the slip distribution are estimated using a fixed fault surface (that may include more than one fault segment).
