The rupture process of the great 1989 Macquarie Ridge (MW=8.1) strike-slip faulting earthquake is examined using an empirical Green function deconvolution method which provides broadband source time functions from both body and surface waves. Recording from a nearby, much smaller (MW=6.4) strike-slip event provide accurate broadband Green functions for PP, S, SS, Rayleigh, and Love waves, spanning the period range 20--150 s. Body wave deconvolutions indicate that the principle short-period (<30 s) moment release occurred in the first 25 s of rupture with no resolvable directivity; only minor short-period energy release occurred over the next 30 s. Surface wave deconvolutions for the usually neglected 20--150 s period range produce source time functions with slightly larger total moment than the body wave deconvolutions and no resolvable directivity from the onset to the peak of moment release in the first 20 s. However, azimuthally dependent broadening of the surface wave source functions, which extend to more than 50-s duration, indicates a component of northeastward unilateral rupture extension requiring about 30--50 km asymmetry in the overall rutpure, compatible with the northeastward asymmetry of the 1-day aftershock zone. Spectral inversions of long-period Love and Rayleigh waves indicate a centroid time shift of approximation 25¿3 s (50¿7 s duration trapezoid source) in the period range of 150--280 s, compatible with the deconvolved surface wave source time functions. Deconvolutions using both empirical and theoretical Green functions are optimized to detect any long-period precursory radiation for periods up to about 250 s, but no convincing evidence for precursory radiation in the passband is found. The long-period surface wave phase data also do not require a precursor. ¿ American Geophysical Union 1995
