Abstract

Time distance curves of seismic first breaks may be looked upon as consecutive straight lines (velocity of refractor and overburden constant) or more realistic as consecutive lines slightly curved (velocity of refractor and/or overburden increasing with depth). In the last case raypaths are curved and the first breaks correspond to diving waves penetrating the refractors.
