在地震活动区的局部地壳地震活动性很大程度上是随机的,但在某些情况下,小的地方震的震级时间序列却具有确定性的分量,此分量很可能与一个大地震的成核有关。当小地震事件中最大的事件变小,最小的事件变大,并且它们的差别不断地减小,这个分量在地震记录上就表现为由震级的两个反向实时趋势产生的所谓能量楔。在一个大的成核事件的震源区,利用相图法,笔者依据非线性动力学已经解释了地震过程的演化和小震的大小分布。模拟地震过程的这种新的处理方法和数学模型已经被应用于来自世界各地区的大批地震目录数据,特别是中国的地震数据。
The local crustal seismicity in the seismic activity area is largely random, but in some cases the magnitude sequence of small local earthquakes has a deterministic component that is likely to be related to a large earthquakes Nuclear related. When the largest event in a small earthquake event becomes smaller and the smallest event becomes larger, and their differences continue to decrease, this component appears on the seismic record as a so-called energy wedge generated by two reverse real-time trends of magnitude. In the focal area of a large nucleation event, using the phase diagram method, the author has explained the evolution of the seismic process and the size distribution of small earthquakes based on the nonlinear dynamics. This new approach to modeling seismic processes and mathematical models has been applied to a large number of seismic catalog data from all regions of the world, particularly to China’s seismic data.
