地震活动性的普遍和非普遍远区相关性：随机矩阵方法

用非广延Tsallis统计量证明区域地震活动的自仿射性质

Verifying the self-affine nature of regional seismicity using nonextensive Tsallis statistics

断层和裂缝的自仿射性质在野外观测和室内实验的数据分析中得到了广泛的证实。在这个方向上，Huang和Turcotte指出，区域地震活动的统计可能仅仅是震源物理过程的宏观反映，即单个断层的活动是区域地震活动的简化自仿射图像。这项工作验证了上述建议。更确切地说，我们表明，人口：（一）地震之前的一个重大事件，并发生在其震中，（二）“断裂电磁地震”，出现在断裂的强大实体分布沿激活单一故障维持系统遵循相同的统计，即，相对累积地震数量对震级。分析主要是通过最近推出的非广延地震动力学模型，导致古腾堡-里希特型法律。我们研究的变化参数$q$和$α$，这是包括在非广延法律，为不同的阈值的震级和不同的震中周围的半径。这种分析增强了潜在的自我亲和力的物理背景。参数$q$描述了Tsallis熵与扩展Boltzmann-Gibbs熵的偏差，并且$α$是碎片断裂期间释放的能量与其尺寸之间的比例常数。

Seismogenic nodes as a viable alternative to seismogenic zones and observed seismicity for the definition of seismic hazard at regional scale

It is shown that considering a fixed increment of a given magnitude at a fault is equivalent to factoring the mechanical moment at the fault as done in structural engineering with the applied loads, by the most currently used structural engineering standards (e.g. Eurocodes). A special safety factor is introduced and related to the partial factor acting on the mechanical moment representing the fault. A comparison is then made between the hazard maps obtained for Italy with the Neo Deterministic Seismic Hazard Assessment (NDSHA) technique, using two approaches for the definition of the seismic…

On the correlation of earthquake occurrence among major fault zones in the eastern margin of the Tibetan Plateau by Big Data Analysis

The subsequent series of responses to big events may exhibit a synchronicity of event number, frequency and energy release in different fault zones. This synchronicity is a reliable source for probing non-intuitive geological structures, assessing regional seismicity hazard map and even predicting the next big events. The synchronicity of main faults in the eastern margin of the Qinghai-Tibetan Plateau is still unknown to us. We propose to examine the correlation of earthquake occurrence among different fault zones to indicate this synchronicity, and to obtain a preliminary understanding of ge…
