The two major subjects were considered based on a result of the shaking experiment of a slope model under 1G field in this paper. One is the behavior to being unstable from stability of a slope. Second is applicability of Newmark method for the behavior beyond the stable limit behavior. The existing experimental data obtained by shaking table tests of slope models under 1G were used. The slope models consisted of 3 layers such as surface layer, weak layer and base layer. Among the models, the heights were 1.0m for small size model, 2.0m for medium size model. The occurrence location of slip surface is restricted in the weak layer. It is found that slip surface is formed by connecting shear cracks which have formed discretely after generating a tensile crack in the top, and that the yield acceleration is the same with the acceleration which acts on a slope when collapsing against a sinusoidal input wave. Furthermore, appropriate consideration is necessary to use the Newmark method for a design because the variation in the estimated value according to the strength characteristic is very large.
