Based on study of the presursor anomalies, the total area of fault surface and the frequency of small earthquakes, the level of qroundwater, the nature electric potential, the apparent resistivity, the plant electricity, the radon concentration in qroundwater, the ground tilt and so on prior to the Mengzi earthquake with M = 5.8, we think that the starting times of the various precursor anomalies have not displayed the feature of synchronous development as a certain theoretical model and that just the apposite,...

Based on study of the presursor anomalies, the total area of fault surface and the frequency of small earthquakes, the level of qroundwater, the nature electric potential, the apparent resistivity, the plant electricity, the radon concentration in qroundwater, the ground tilt and so on prior to the Mengzi earthquake with M = 5.8, we think that the starting times of the various precursor anomalies have not displayed the feature of synchronous development as a certain theoretical model and that just the apposite, the various precursor anomalies have displayed obvious features of phase. All precursors of the Mengzi earthquake, except some precursor indexes of seismic activity began to take on themselves one year before the earthquake, took on themselves only 2-3 moths before the earthquake. Therefore it is considered that the observation data for geophysics, geochemistry and qroundwater only can reflect some dangerous informatious of short term and imminent stage before a magnitude M= 5-6 moderate earthquake.

本文通过蒙自5.8级地震前,小震断层面总面积和频度、地下水位、自然电位、视电阻率、植物电和水氡浓度、地倾斜等前兆异常的研究,认为各类前兆异常的开始时间并不象有关理论模型那样显示出同步发展的特性。恰恰相反,不同种类的前兆异常显示了明显的阶段性。蒙自地震的前兆显示中,除地震活动性的某些指标,在一年以前开始显出一定程度的异常外,其它前兆仅出现于震前2—3个月。因此认为,对于一个5—6级的中强震,利用地球物理、地球化学、地下水等观测资料,仅能反映短期和临震阶段的某些危险信息。

There is a high fitting rate between the El Nir(?) and the great prevailence of the wheat scabin the areas along the ChangJiang River.The analysis in a chain of relationships among El Ni-n(?)—subtropical high pressure—cool summer,sodden winter and warm wet condition—great pre-vailence of the wheat scab have been made in this paper.It shows that there are close relationsamong these factors.So,the outbreak of El Nin(?) can be taken as the precursor index.

本文分析了厄尼诺——副热带高压——“凉夏”、“烂冬”、“暖湿条件”——小麦赤霉病大流行之间的关系。结果表明,它们之间均存在较好的关系。所以认为厄尼诺现象的出现可作为长江流域小麦赤霉病大流行的前兆性指标。

In this paper the direct computing method of precursor information content of anomalies is put forward,and the transformation of non-dimensional precursor information content of precursory anomalies of various observation data has come true. By means of this method we have accomplished the calculation of precursor information content of correlative anomalies which are extracted from the difference values of five-day average from 92 observation items distributed over Gansu,Ningxia and Qinghai.On...

In this paper the direct computing method of precursor information content of anomalies is put forward,and the transformation of non-dimensional precursor information content of precursory anomalies of various observation data has come true. By means of this method we have accomplished the calculation of precursor information content of correlative anomalies which are extracted from the difference values of five-day average from 92 observation items distributed over Gansu,Ningxia and Qinghai.On the basis of reviewed research on the 2 4 Ms≤5.0 earthquakes we have obtained effective average information contents of unit anomaly about 92 observation items,which become not only important references for earthquake prediction but also a good foundation for the further research on the precursor index system. According to the statistical analysis on the change characteristics of precursor information of Ms≥5.0 earthquakes,the reference indexes of three elements of earthquake prediction are given.

本文提出了异常前兆信息量的直接计算法,实现了各种观测资料前兆异常的无量纲前兆信息量转换。用该方法对甘、宁、青地区5种观测手段共92个测项的5日均值一阶差分相关异常进行了前兆信息量计算。通过24次5级以上相关地震的回顾性分析研究,求得了92个测项的有效单位异常平均信息量,为前兆标志体系的进一步研究打下了良好的基础。又通过7次7级以上相关地震前兆信息量变化特征的统计,给出了一组预报地震三要素参考指标。
