查询词典 earthquakes

One bine is that some occurred earthquakes are regarded as the "cause" of coming earthquakes, that is as the occurred earthquakes produce effect on regional stress fields, which result in the occurrence of relatively strong earthquake.

一类是以已经发生的一些地震作为未来可能发生的地震的"因"，即由于已经发生的地震对区域应力场的影响，导致未来发生较强地震。

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.

在系统分析并筛选出华北地区地震频度、地震活动标度、mf值、调制比、b值、D值、η值、地震活动强度熵和地震活动时间熵等映震较好的9项测震学参数基础上，应用综合异常指数方法，分别计算了它们各自的地震异常指数时序值，进而合成得到华北地区测震学综合异常指数时序曲线，通过研究其地震短期异常特征，给出了华北地区M≥5.8地震短期综合预测的判据指标，经R值评分检验表明，该指标具有较好的地震预测效能。

During the preparatory periods of the Haicheng earthquake and Tangshah earthquake, the occurrences of the stronger earthquakes in the precursory field were related to the moon's phase, the M_L≥4.5 earthquakes of the near-focus field in the trend precursory periods and the M_L≥4.0 earthquakes of the whole precursory field in the periods of the fast-changing precursors tended to occur around syzygy or quarter.

海城和唐山地震的孕震期间，前兆异常区域内的较强地震趋于发生在朔望和上下弦，海城和唐山地震的主序列以及前兆异常区域内1900年以来发生的六级以上强震与月相也存在类似的相关。这些关系可以在地震预报中作参考。

The results indicate that the distribution of the solar zenith distance versus the occurring probability of earthquakes is quite consistent with the lunar case, and the case for small earthquakes is different from the larger earthquakes. The latter is mainly clustered at 0oand l80o of the zenith distance, and consistent with the distribution of the absolute value of the solar tide forces, while the former are clustered at 60o and l2Oo.

统计发现：地震的太阳天顶距地震频度和月球天顶距地震频度分布表现出一致的规律性，且较大地震和小地震的活动规律不同，较大地震丛集发生在太阳天顶距0°和180°附近，与地面引潮力的绝对值分布有较好的一致性；而小地震多丛集在太阳天顶距60°和120°附近。

We use the earthquake situation trichotomy method to deal with the datum of small earthquakes in Huabei region, the result shows, the relativity between group seismic precursor informaitons and large earthquakes is rifeness phenomenon of large area, the shake of large earthquakes are globality, the remote correlation of shake are globality.

采用&震情三分律&的方法处理了华北地区小震活动的数据，分析认为成组震兆的出现与大震之间的遥联性绝不只是一种小区域性的现象，而是一种大范围的普遍现象，大地震是全球性的震动，其震动遥联性的显示，就必然是跨越全球性的。

The results show that Chi-square test can reveal not only the swarming feature of earthquakes before medium and strong earthquakes,but also close relation between strong earthquakes and seismotectonic background.

认为，卡方检验不仅揭示了中强震前地震的丛集特性，而且体现了强震与地震地质背景之间的密切关系，揭示了构造体系与地震的某些联系。

The result show there weren't M6.0 earthquakes beyond 4 years and M5.0 earthquakes beyond 2 year, the earthquake calmness is distinct in medium term; the M5.0 earthquakes intensified in short term, there were foreshocks in the epicenter region, in the same time, the fixed point precursor observational datum of Xinjiang appeared obvious short anomalies; and found a few imminent earthquak...

结果认为，6.8级地震前新疆6级地震平静4年多，5级地震平静2年，中期阶段地震平静显著；短期阶段5级地震显著增强，震源区出现前震活动，同时全疆定点前兆观测资料出现较为明显的短期异常并观测到少量的临震异常。不同孕震时段的异常特征是6.8级地震中短期预测的依据，因而也是当前经验预报的基础。

0 Earthquakes in Jiashi strong earthquake sequence are analyzed, among which there are 8 strike slip earthquakes and 5 dip slip earthquakes.

分析了伽师强震群序列中 1 3次 5级以上地震的震源机制解资料，其中有 8个走滑型地震、5个倾滑型地震。

The competent administrative departments or institutions for seismic work under the local people's governments at or above the county level in areas where destructive earthquakes may occur shall, together with the departments concerned, work out emergency preplans for destructive earthquakes in their own administrative areas in the light of the national emergency preplans for destructive earthquakes and submit them to the said people's governments for approval.
