摘要翻译:
在二维粘滑模型中,我们研究了地震间隔时间统计,特别注意了发生间的时间。间发时间是一个区域内所有断层上连续发生地震的时间间隔。我们选择刚度和摩擦参数作为可调参数,因为这些物理量是描述故障动力学的基本因素。发现发生间时间统计量依赖于参数。系统地改变刚度参数和摩擦参数,对这些参数进行优化,以再现天然地震活动中的发间时间统计。在最优情况下,模型产生的地震服从Gutenberg-Richter定律,即震级-频度分布呈现指数近似为1的幂律。

英文摘要:
We study earthquake interval time statistics, paying special attention to inter-occurrence times in the two-dimensional (2D) stick-slip (block-slider) model. Inter-occurrence times are the time interval between successive earthquakes on all faults in a region. We select stiffness and friction parameters as tunable parameters because these physical quantities are considered as essential factors in describing fault dynamics. It is found that inter-occurrence time statistics depend on the parameters. Varying stiffness and friction parameters systematically, we optimize these parameters so as to reproduce the inter-occurrence time statistics in natural seismicity. For an optimal case, earthquakes produced by the model obey the Gutenberg-Richter law, which states that the magnitude-frequency distribution exhibits the power law with an exponent approximately unity.
