摘要

利用分布函数对泽穆里地震资料进行了统计检验。运用了帕累托定律，计算了各种预期地震的概率。建立了给出分位数的数学表达式。极值限制规律证实了平差方法的准确性。利用矩震级，建立了预测强震发生的概率模型。用递归图的斜率γ、分形维数D、浓度参数Ksr、Hurst指数Hr和Ht对地震构造进行了表征。D、γ、Ksr、Hr和Ht值在研究的地震活动性带发生主震(M = 6.9)前几个月就减小了。地球物理介质变形的三个阶段表现在小地震事件聚类系数G%的变化上。

Some Probabilistic and Statistical Properties of the Seismic Regime of Zemmouri (Algeria) Seismoactive Zone

Statistical tests have been used to adjust the Zemmouri seismic data using a distribution function. The Pareto law has been used and the probabilities of various expected earthquakes were computed. A mathematical expression giving the quantiles was established. The extreme values limiting law confirmed the accuracy of the adjustment method. Using the moment magnitude scale, a probabilistic model was made to predict the occurrences of strong earthquakes. The seismic structure has been characterized by the slope of the recurrence plot γ, fractal dimension D, concentration parameter Ksr, Hurst exponents Hr and Ht. The values of D, γ, Ksr, Hr, and Ht diminished many months before the principal seismic shock (M = 6.9) of the studied seismoactive zone has occurred. Three stages of the deformation of the geophysical medium are manifested in the variation of the coefficient G% of the clustering of minor seismic events.
