Abstract
A method is provided for measuring the surface travel time of a surface wave between first and second points on a surface. First and second spaced apart transducers are disposed substantially perpendicular to a surface. The direct travel times for each transducer are determined, then a total travel time from the first transducer to the second transducer is measured. The direct travel times are subtracted from the total travel time to produce the actual travel time between the points on the surface.
