连云港─银川岩石圈壳─幔组合结构剖面构造应力场的有限元数值模拟

从岩石圈壳－幔组合结构出发，选择了大华北岩石围块体内一条NWW向连云港－银川的岩石圈壳－幔组合结构剖面，试图先从一个简单的力学模型开始，用二维有限元法得到岩石围（地壳和上地幔顶盖层）中的构造应力场的分布特征，从而解释板内地震与　岩石围亮－幔结构比值（R）相关的力学原因。     

Seismicity in Major Seismotectonic Provinces of Iran

Seismicity parameters,i.e.,seismic activity rate,X,the so-called Gutenberg-Richter b value(orβ),and maximum possible magnitude,Mmax,for major seismotectonic provinces of Iran are estimated through the application of Kijko and SellevolPs uncertainty models.The uncertainty models facilitated the estimation of seismic activity parameters from incomplete and uncertain data files in the catalog of earthquakes in major seismotectonic provinces of Iran.Zagros has the highest seismic activity rate,and is characterized by the occurrence of mainly small-and mid-sized earthquakes.Kopeh Dagh has the lowest activity rate but is characterized by a greater occurrence of major earthquakes.However,the Makran and Alborz-Azarbayejan seismotectonic provinces are most likely the regions which are capable of generating great earthquakes.

Discrimination Between Nuclear Explosions and Earthquakes: An Application of Wigner Distribution

In this paper,the nonstationary theory of Wigner Distribution is used to discriminate between underground nuclear explosions and natural earthquakes.Five underground explosions in Kazakhstan region and seven regional earthquakes in its adjacent areas have been analyzed.The result shows that the transient spectra of underground nuclear explosions are concentrated in the frequency range of 5-10 Hz,while the transient spectra of natural earthquakes are distributed widely from lower frequency to higher frequency.The transient frequency of nuclear explosions shows linearity in the first stage(0相似文献
