在SNREI地球中点位错激发的静态变形与潮汐力、表面载荷和表面剪切力等外力产生的静态变形之间存在着有趣的相互作用关系。同震形变可改写为：（1）潮汐形变场的势变，（2）荷载和潮汐形变场的径向位移，（3）剪切和扭转形变场的切向位移。这些关系大大减少了球对称地球同震地壳形变的计算工作量。
Intriguing reciprocity relations exist between the static deformation excited by a point dislocation in a SNREI earth and those generated by external forces, such as tidal force, surface loading and surface shear forces. Coseismic deformations can be rewritten as follows: (1) potential change in terms of the tide deformation field, (2) radial displacement in terms of the load and tidal deformation fields, and (3) tangential displacement in terms of shear and torsional deformation fields. The relations greatly reduce the effort to compute the coseismic crustal deformation in a spherically symmetric earth.
