Developed in the mid-1970s to answer the need for a technique that could measure seismic shear-wave velocities in deep, uncased boreholes, it was originally used by researchers at the OYO Corporation of Japan. The Method gained acceptance in Japan in the mid-1980s and was used with other velocity measurement methods to characterize earthquake site response.
