孕震

对每个孕震区，Pk>0.08的期间是安全期，反之为危险期。

On the contrary , the period of Pk < 0.08 will be danger .

Evolution process of high b value and seismogenic mode before the Lijiang M7 earthquake

仔细分析不同的震级段，b值是有差异的，这与孕震体的内在恃性有关。

By careful analysis of the different magnitude sections , b values are different , which is related with the inherent characteristic of the seismogenic body .

利用KCl与水相互作用呈现出来的类流态特征，进行岩石破裂机理及地震孕震机理的研究是一种新的方法。

According distinctions of quasi-fluid appeared after reciprocity of KCL and water , the rock burst and seismogenic mechanics were studied well .

在孕震过程中，增强区经历了一个走向由NE向变为NW向、区域由大变小的过程；

In the process of earthquake preparation , the strike of the seismicity enhanced region was changed from NE to NW , and its size was changed from big to small .

日本东北宫城北部1962年M6.5地震孕震区的电磁不均匀性

Electromagnetic heterogeneity of the seismogenic region of 1962 M6.5 Northern Miyagi earthquake , northeastern Japan

本文应用构造块体成组孕震模型的研究结果，探讨了中国大陆MS≥7.0地震的成组活动和引潮力的调制触发关系。

The results obtained with the group model of earthquakes generated in tectonic blocks are further used in this paper to analyze the relationship between the M S ≥ 7.0 events in the Chinese mainland and the modulation and triggering from the earth tides .

汶川MS8.0地震孕震机理的形变证据与模型推演

Deformation Evidence and Model Deduction about the Generation Mechanism of the Wenchuan M_S8.0 Earthquake

本文还讨论了地震前τH/τV短临异常的物理机制，认为异常的产生与孕震期间介质内裂隙的出现和闭合有关。

The paper also discusses the physical mechanism of the τ _H / τ _V short and imminent anomalies , and rends to think that the occurrences of the anomalies are related to the appearance and closure of the cracks in the medium in earthquake preparatory stage .

系统研究了多种地震活动性方法后认为，1970年以来华北地区发生的Ms≥5.8中强震前，约83%具有3级或4级地震异常条带、孕震空区及信号震出现。

After studying different kinds of earthquake activities systematically , we have found that about 83 % of the anomalous seismic bands , seismogenic gaps and signal earthquakes with magnitudes 3 or 4 appeared at the same time before moderately strong earthquakes ( ML36 ) since 1970 in North China .

从更深层次上来看，ZK值的变化从地震空间分布的角度出发，在某种程度上反映了孕震系统有序复杂程度的动态变化。

When Zk approached O , it possibly corresponds to the network distribution pattern of earthquakes . From the angle of the seismic spatial distribution , Zit-value changes reflected the dynamic variation of the ordered and complicated degrees of seismogenic system to some extent .

本文从楚雄地震台FSQ型水管仪的原始资料出发，探讨了澜沧、耿马大震前地形变前兆信息量的问题，指出了孕震体的变化过程。

Based on the original data recorded by type FSQ float water piper from Chuxiong station , the authors made an approach on quantity of precursory informations of deformation and put out the process of seismogenic varying body before the great Lancang Gengma shock .

由此观点结合实际地震资料得到中国大陆大震的下限震级为7.1，相应的孕震层厚度为20km。研究了强震造成地表破裂的宽度范围，得出造成地表破裂的下限震级是66级。

Based on the view , combining actual seismic data , the author draws the conclusion that the lower & limit magnitude of strong earthquake is 7.1 in Chinese Continent , and the thickness of seismogenic layer is 20km . Surface fault width caused by strong earthquake is studied .
