ABSTRACT: A novel
methodology to quantify the spatial resolution in 2-D seismic surface wave
tomographic problems is proposed in this study. It is based on both the
resolving kernels computed via full resolution matrix and the concept of Full
Width at Half Maximum (FWHM) of a Gaussian function. This method allows estimating
quantitatively the spatial resolution at any cell of a gridded area. It was
applied in the northeastern Brazil and the estimated spatial resolution range
is in agreement with all previous surface wave investigations in the South
America continent.
