1906年12月23日北京时间2时21分在新疆玛纳斯西南发生的八级地震,历史资料虽有记载,但有关地面破坏的详细情况则无反映。自1972年以来,我局所属地质人员曾多次深入震区调查访问,已作了几个专门总结。本报导在此基础上,就地震的地表破坏现象和发震构造问题作一简略的介绍。 On December 23, 1906, at 2:21 PM Beijing time, an earthquake of magnitude 8 occurred in the southwest of Manas, Xinjiang. Although historical records have been recorded, the details of the damage to the ground are not reflected. Since 1972, the geological staff affiliated with the Bureau have conducted in-depth investigations on the quake-hit areas. Several special sums have been made. Based on this report, this report gives a brief introduction of the surface damage caused by earthquakes and the seismogenic structure.
