Tectonic Features of the Earths Crust and Upper Mantle

Abstract

A discussion is given of the quality of the data obtainable from carefully selected Rayleigh Surface Waves traversing the North American continent. Using data from five events, a phase velocity map is constructed for the United States, the Canadian Shield, and Greenland. Average values are computed for various regions of this area and are given in a table and compared from region to region as well as with previous results.
