| 摘 要： | 本文利用半经验、半理论的方法对世界各主要地震汇集和研究机构所给出的集集主震基本震源参数进行了综合计算和评定。根据这些参数重新计算了集集主震的标量地震矩、破裂面积、应力降等。根据这些参数之间的内在联系,从地震分类学的角度,判定集集地震是发生于板块边缘的大地震。可供研究台湾岛上地震活动性以及台湾地区板块构造演化问题参考。

| Abstract: | In the paper,using the semi experiential and theoretic method ,it was calculated and assessed that the basic seismic source parameters of jiji earthquake from the main seismic research institutes in the world. According to the parameters,it was newly calculated that the seismic moment ,the rupture area and the stress drop.According the inherent relation between the parameters ,from the seismic taxonomic opinion ,it was assessed that the jiji earthquake occurred in the plat edge.It could provided reference for the research about the seismicity and tectonic evolvement in Taiwan island. |
