Fig. 17From: High-resolution mini-seismic methods applied in the Mont Terri rock laboratory (Switzerland)Seismic anisotropy in a horizontal plane. Angle-dependent vp variation of all 576 emitter–receiver combinations in a polar diagram. Note the limited angle coverage. Nevertheless, the data fits well with an elliptical fit, after the EDZ-related vp values were excluded. Four ray coverages are shown as small insertsBack to article page
