Abstract:From the point of view of dynamic state, "rhythm" and "golden cut value" (that is, optimal selected value) are used to describe the migration characteristics of the strong seismic activities of the latest epoch in North China. The result is called "Dynamic rhythm" and the elliptical pattern visually shows the largest permissive rhythm range in space. In this paper, it has been considered that such "Dynamic rhythm" is the concrete expression of characteristics of neotectonic movement. It may make some contribution to estimation of earthquake tendency to study the "Dynamic rhythm" of seismic activity in every seismic zones.
