摘要
本文提出了一个模拟地震活动性的层次结构模型,它所产生的地震活动性是分形的。根据该模型本文导出了Gutenberg-Richter统计关系式,并建立了分维数D与b值间的定量关系。同时还导出了不同震级地震间的平均震中距公式,该公式表明分形几何学在地震预报中有实际应用价值。
A hierarchy model simulating seismicity has been proposed, which can produce fractal characteristics of seismicity, such as Gutenberg-Richter relationship. Quantitative relation between fractal dimension D and b-value is obtained. The average epicenter distance between the earthquakes with magnitude m is derived by using the hierarchy model, which can be used to seek the potential earthquake regions.
