Seismic Travel Time Study
Abstract
The report consists of an introduction in which is given a list of published papers on the travel times of body waves together with brief comments on the results. The main body of the report describes a new determination of the velocity distribution in the outer core. Earlier studies of the velocity distribution in the outer core have been based on the travel times of SKS. However, SKS arrivals can only be observed satisfactorily for arc distances at the surface greater than 83 degrees. This lower limit of observation of SKS corresponds to an arc distance of 40.2 degrees within the core. Thus the velocities in the outermost 250 km of the core are based upon an extrapolation.
