环太平洋NW地震带孕震的统计性质和动力学--基于非广延统计物理的研究
On the Statistical Nature and Dynamics of Seismogenesis in the NW Circum-Pacific Belt: A Study Based on Non-Extensive Statistical Physics
摘要：
我们询问的统计性质和动力学的浅，深地震沿主要板块边缘的西北环太平洋带，通过检查地震是否产生的泊松过程，是独立的（不相关），或复杂的过程，是依赖（相关）。分析基于非扩展统计物理学和日本气象厅2002- 2016年期间的完整和均匀目录。重点是背景地震恢复消除余震随机去聚类。在浅源背景地震活动中，长期相关和长期相互作用多为弱到中等。相反，深地震活动大多是不相关的（准泊松），特别是在贝尼奥夫带。作为时间的函数，浅层背景地震活动表现出持续的弱到中等的相关性，地壳下的背景地震活动一般是准泊松，但可能会动态过渡到中等显着与大地震的时间集群。在2011.19年东北大地震之前观察到了普遍的这种效应。这些结果对比沿太平洋-北美转换板块边界的加利福尼亚州和阿拉斯加州，这是一般相关的观测，表明地球动力学设置是必不可少的自组织和复杂性的发展。此外，观测结果似乎与小世界断层网络的模拟一致，其中表面的自由边界条件允许复杂性发展，而深度的固定边界条件则不允许。
英文摘要：
We inquire the statistical nature and dynamics of shallow and deep seismogenesis along major plate margins of the NW Circum-Pacific Belt, by examining whether earthquakes are generated by Poisson processes and are independent (uncorrelated), or by Complex processes and are dependent (correlated). Analysis is based of Non Extensive Statistical Physics and the complete and homogeneous catalogue of the Japan Meteorological Agency for the period 2002-2016.5. Emphasis is given to background seismicity recovered by removing aftershocks with stochastic declustering. Long-term correlation and long-range interaction is mostly weak to moderate in shallow background seismicity. Conversely, deep seismicity is mostly uncorrelated (quasi-Poissonian), particularly in Wadati-Benioff zones. As function of time, shallow background seismicity exhibits persistent weak to moderate correlation; sub-crustal background seismicity is generally quasi-Poissonian but may dynamically transition to moderate-significant in association with temporal clusters of large earthquakes. A universal such effect was observed ahead of the 2011.19 Tohoku mega-earthquake. These results contrast observations along the Pacific-North American transformational plate boundaries of California and Alaska which are generally correlated, suggesting that the geodynamic setting is essential in the development of self-organization and Complexity. Moreover, observations appear consistent with simulations of small-world fault networks in which free boundary conditions at the surface allow for Complexity to develop, while fixed boundary conditions at depth do not.
