Large Three-component seismic data sets from microseismic and                   controlled sources in a widespread variety of tectonic and                      lithologic environments - geothermal, deep crustal, ocean floor,                seismotectonic, and sedimentary - have yielded evidence for                     anisotropic shear wave velocities.  The observed effect of                      anisotropy, called shear wave splitting, is an analog of optical                birefringence in calcite, and for the upper crust may be                        interpreted in terms of a population of oriented vertical                       microcracks or fractures in the crust.  As fracture populations,                particularly aligned fracture populations, tend to control                      hydraulic conductivity in crystalline and sedimentary rock, there               is a wide-ranging interest in identifying, interpreting, and                    modeling the seismic evidence for in situ volumes of aligned                    fractures.  The study and interpretation of oriented crack                      fracture system in the crust is the principal purpose of the AGU                Chapman Conference on Seismic Anisotropy in the Crust to be held                at the Lawrence-Berkeley Laboratory, Berkeley, California, May 31               to June 4, 1988.
