地震活动性

His paper is to summarize and restudy the midlong term prediction of ZhangbeiShangyi earthquake throuth seismic activity analysis.

Unfortunately, however, there is serious question about the accuracy and reliability of proposed methods for long-term seismicity forecasts.

然而，遗憾的是，对于长期地震活动性预测所提议的方法的准确性和可靠性方面存在着严重的问题。

They wanted to hear more details about changing water levels and local, lower-level seismicity.

The latter briefing the Workshop on Pattern Recognition and Analysis of Seismicity run in Italy.

介绍了在意大利举办的"地震活动性的模式识别与分析实习班"概况。

How should we compositively account for the three kinds of seismic data? In this study,we introduce seismicity model.

如何综合考虑这三种地震资料，本文引入了地震活动性模型。

For earthquakes between M6.5-7.0 and the largest potential earthquake in the region,we should account for other two models including geodetical model and fault model.From physical aspect,we can constrain seismicity parameters by utilizing GPS data and fault slip rate.

对于震级6.5或7.0级以上的地震危险性分析，可以考虑另外两种模型，即大地测量和断层模型，从物理的角度，利用GPS数据和断层滑动速率来约束地震活动性参数。

There were 25 seismic stations within the distance of 200 km from the epicenter.15 of them were seismometric observation stations and the other 18 of them were precursory observation stations.

在震中200km范围内共有地震台站25个，其中开展测震观测台15个，其他前兆观测台18个，5.8级地震前共出现10项异常，其中地震活动性异常4项，其他前兆观测异常6项。

Through statistics and analyses of the seismicity, and combining the corresponding research results on paleoearthquakes, the recurrence behavior of continental strong earthquakes in areas with more than one seismotectonic belt or fault zone is investigated from the pointview of statistics.

通过时间序列等地震活动性统计和分析，并结合区域古地震研究结果，从统计学角度探讨了具有多个孕震区或断裂带的大陆板内地区的地震复发行为。

For example, by using the functions of GIS for map layers piling and combination, data query and comprehensive analysis, the seismotectonic map of Eastern Asia Region is compiled, the potential seismic source area of the region is delineated and their seismic activity parameters are obtained respectively. On the bases of these, the peak ground accelerations with probability of exceedence of 10%in 50 years for Eastern Asian Region are computed and assessed by 1°×1°.

以东亚地区地震危险性分析为例，在GIS平台下，利用GIS的图层叠加和拼接、空间数据查询和综合分析功能，编制了东亚地区地震构造图，划分了该区的潜在震源区，并得到了各潜在震源区相应的地震活动性参数，在此基础上，按1°×1°计算和分析了东亚地区未来50年超越概率为10％的峰值地面加速度。

A strong earthquake with magnitude 6.1 took place on March 19, 1962, about two and a half years since the impounding of the reservoir.

结合地震活动性和地质背景初步讨论了新丰江水库地震的诱发机制，认为：水的渗透作用是诱发这次地震的主要原因。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
