A Future for Drifting SeismicNetworks
Abstract
Earth models in which seismic wavespeeds vary only with depth are sufficientlywell constrained to accurately locate earthquakesand calculate the paths followed byseismic rays [Engdahl et al., 1998]. The differencesbetween observations and theoreticalpredictions of seismograms in such one-(hyphen)dimensionalEarth models can be used toreconstruct the three-dimensional (3-D)wave speed distribution in the regions sampledby the seismic waves by a procedureknown as seismic tomography, a techniqueakin to medical CAT scanning.
