摘要
将自组织临界现象理论在地震预报领域作深入的应用研究,根据各量的物理含义重新讨论了在地震科学中的应用,并用重整化群方法对强震前中小地震增强现象的临界点问题进行研究,将临界概率、相关长度的临界值定量化.空间演化图实际上是一种定量的地震活动分布图,可用于估计未来地震发生的空间范围.
The theory of self-organized critical phenomenon is used to do a deepgoing research in earth- quake prediction.Based on the physical meaning of all the variables,their usability in seismic sci- ence is discussed.The critical point problem about increasing small or moderate events before a strong earthquake is studied.Both the critical probability and the threshold of the correlation length are quantified.The spatial evolution pattern is essentially a kind of quantitative seismicity distribution map and can give approximate prediction for the spatial position of a future earthquake.
