Abstract
We describe two methods, suitable for routine application to teleseism ic recordings, that characterize the time history of seismic events. S tacking short-period signals from large regional arrays provides stabl e estimates of high-frequency radiation from the source, and an empiri cal Green's function deconvolution procedure extracts reliable, broadb and time functions suitable for analysis of faulting complexity and th e spatio-temporal extent of rupture. Combined, these procedures charac terize the source radiation of large events (M(S) > 7) between 200- an d 0.5-sec periods.
