Electronic transitions produced from insulator surfaces by grazing impact of fast ions are investigated, considering two different situations:  planar and axial surface incidence.   The planar incidence corresponds to a random orientation of the projectile trajectory with respect to the crystal axes, while the axial incidence is related to projectiles moving along precise strings of surface atoms. In both cases we employ distorted-wave methods to describe electron capture and emission processes.
