Closed-form expressions are deduced and discussed, using an extended form of the classical dislocation layer method, for the phonon and phason stress and electric displacement components and intensity factors generated in one-dimensional piezoelectric quasicrystals by a collinear row of moving shear cracks. Representative numerical results are presented graphically. Additionally, this analysis yields the fields of a single crack moving in a finite piezoelectric quasicrystalline plate and also of a moving edge crack in a plate
