b-value of the Gutenberg–Richter relation as an earthquake precursor depends on the tectonic setting features. This paper presents an alternative method to calculate b-value in the presence of characteristic earthquakes. The proposed equation is based on the maximum likelihood method applied on the probability density function of the characteristic earthquake model. Data from real and simulated catalogs were used to evaluate the accuracy of the proposed model. For this purpose, 224 seismic event catalogs with various properties including catalogs’ sample size, the ratios of characteristic earthquakes number to catalog’s sample size (Rnc) and different magnitude of characteristic earthquakes were simulated. According to the estimated b-values, the earthquake occurrence probability was calculated and discussed. The results indicate that the proposed method of estimation for b-value has more adaptable consideration of the characteristic earthquake behavior.

基于特征地震模型的b值估计

b- Gutenberg-Richter 关系作为地震前兆的值取决于构造环境特征。本文提出了另一种计算方法b- 存在特征地震时的值。所提出的方程是基于应用于特征地震模型的概率密度函数的最大似然法。来自真实和模拟目录的数据用于评估所提出模型的准确性。为此目的，224 个具有各种属性的地震事件目录，包括目录的样本量、特征地震数与目录样本量的比率(R数控)并模拟了不同震级的特征地震。根据估计b-值，计算并讨论了地震的发生概率。结果表明，所提出的估计方法b-值对特征地震行为有更适应性的考虑。
