The proportion of the seismic energy in the long period range is believed to increase with the size of the earthquake. Considering that soft sites undergo large elongation in .ground period at higher level of shaking, the presence of large long period components can be a destructive consequence. Potential effects of successively increasing levels of long period components are investigated. Response of soft sites is seen to be substantially influenced by long period components. The consequences of deficiencies in short and long period components is also discussed. Various nonlinear ground response characteristics are discussed in these contexts.
