Earlier solutions of deformations resulting from the movements of shear and tensile faults in a half space ( Bull. Seismol. Soc. Amer. 1985; 75 :1135, 1992; 82 :1018) have been revised in view of cross‐anisotropic stress–strain relationships. The dislocation theory ( Canad. J. Phys. 1958; 36 :192) is reviewed and the displacement field due to a concentrated force in an anisotropic half space is solved analytically for developing the current research. A fault is simulated as a point source of strain nuclei in applying the dislocation theory. Data ( Terr. Atmos. Oceanic Sci. 2000; 11 (3):591, 631) that were used to study the Chi‐Chi earthquake ( M L =7.3; 1999/9/21 AM 1:47) are introduced to compare the solution with the isotropic results. Results indicate that the anisotropy of stress–strain relationships does affect the results of predicted deformations. Copyright © 2001 John Wiley & Sons, Ltd.
