【摘要】 对 30°纬圈附近中国的 8级大震活动带的成因提出了天文学解释。认为此处一些 8级大地震的发生可能与月下点最北位置的垂直引潮力效应有关。并提出 ,如果西藏南部及其附近地区存在孕育着的大地震 ,则将在2 0 0 5～ 2 0 0 7年具有被月球引潮力触发的有利条件。更多还原

【Abstract】 Possible astronomical cause of great earthquake belt along 30° latitude circle in China is proposed and discussed. The authors put forward that the occurrence of some great earthquakes (M≥8) in the region is related to the lunar tide-generating force effect of the greatest declination of the Moon. The authors point out that there is the favorable condition triggering the great earthquake by the lunar tidal force during 2005～2007 if there is the gestating great earthquake in the southern Tibet and its neighbouring areas.更多还原
