台湾地区强震成丛性活动初探
|
摘要
文中探讨了我国台湾地区(北纬21.5°～25.5°,东经119.5°～123.0°)自1900年以来5次明显的强震成丛性活动现象,每次成丛性强震活动高潮期的能量释放持续时间由几个月至4年多不等,丛与丛间的间隔时间也各不相同,两者之间似存在着互补的关系。研究认为,这种强震成丛性活动不仅与该区所处的特殊地理环境与构造条件密切相关,还可能与大陆及周沿地区8级以上的巨大地震有关。
In this paper, the author discusses 5 times of strong earthquake activity in cluster way obviously from 1900 to nowadays in Taiwan area (21.5°～25.5°N, 119.5°～123.0°E), the duration of the climax of these strong earthquake activity was different from several months to almost 4 years, the interval of clusters was different too, and there was a complementary relation between duration and interval. These phenomena are related not only to the special geographical environment and tectonics condition, but also to the great earthquake with M8 around the area.
