We have recently begun a
systematic study of surface wave dispersion across South America. We include
below links to graphical images of the group velocity maps. In each case,
images are presented in both gif and postscript format (for down loading),
and the ascii data files are also available for down loading.
This work is still preliminary.
The maps are still being updated, and the images and data files included
here are not necessarily the up to date. No models are available for distribution
yet. To check on the status and availability of the latest maps and models,
contact Oleg Vdovin at the email address listed above.
