| 摘 要： | 本文分析了台湾地区近期 5 5级以上地震的时空图象 ,发现台湾地区从 93年开始5 5级以上地震逐渐形成一条中强地震共轭条带 ,其中主条带长仅 30 0公里左右。强震条带形成后 ,1 999年 9月 2 1日在主条带的西南段 1 /3处条带的西侧边缘南投发生了7 6级地震。南投地震后 ,5 5级以上地震条带仍然存在 ,2 0 0 2年 3月 31日在共轭条带交汇处附近苏沃海外发生了 7 5级地震。在共轭条带内相隔两年半时间里发生两次 7级以上地震实属罕见

| Abstract: | The space time distribution map has been analyzed in the paper.The author found that medium earthquake formed a conjugated stripe and the main stripe with 300km long.After the forming of the stripe,the Jiji earthquake with magnitude 7 3 occurred in September 21,1999.After Jiji earthquake,the stripe still exist and in its intersection the earthquake with 7 5 occurred in March 31,2002.The two strong earthquake occurred in one conjugated stripe are rare. |
