The 27 February 2010 Chile (Mw 8.8) earthquake is the fifth largest
earthquake to strike during the age of seismological instrumentation.
The faulting geometry, slip distribution, seismic moment, and moment-rate
function are estimated from broadband teleseismic P, SH, and Rayleigh
wave signals. We explore some of the trade-offs in the rupture-process
estimation due to model parameterizations, limited teleseismic sampling
of seismic phase velocities, and uncertainty in fault geometry. The
average slip over the \~81,500 km2 rupture area is about 5 m, with
slip concentrations down-dip, up-dip and southwest, and up-dip and
north of the hypocenter. Relatively little slip occurred up-dip/offshore
of the hypocenter. The average rupture velocity is \~2.0-2.5 km/s.
