The determination of joint directions by seismic refraction measurements at the Avedat plateau (Israel)

A seismic refraction experiment was conducted in an area at a site where joints had been mapped in detail in order to determine whether velocity anisotropy could be correlated with joint directions. The purpose was to assess the possibility of using seismic refraction techniques for mapping joint directions in alluvium-covered areas. The results of the experiment show that a velocity anisotropy can be detected by simple seismic refraction measurements, and that the anisotropy can be correlated with the dominant joints. It is believed that the technique is applicable to the determination of joint directions in alluvium-covered areas.
