* 1-D Newmark analysis under-predicts displacement.

* On near-level ground, Maximum Displacement Not equal sign Final Displacement.

* On near-level ground, displacement models based on final measurements are suspect.

* Oscillation of the displaced mass influences shear stresses on the slide plane.

* When Tground About equal to sign (1/n)•Tmotion displacements are amplified over rigid 'Newmark'.

* When Tground >1.2•Tmotion displacements are reduced from the rigid 'Newmark'.

* Neglecting compliance, strike motion and block inertial forces leads to erroneous and sometimes unconservative displacement prediction.
