摘要
汶川8.0级大震后的2008年9—12月,川甘陕交界地区重力观测显示:四川青川县的沙洲-陕西宁强的青木川-甘肃文县的碧口之间重力变化明显,重力变化达70×10-8m s-2,宁强-康县间为重力变化高梯度带。望褒线重力变化活跃,靠近断裂重力变化剧烈。
During September to December of 2008 after Wenchuan Ms8.0 earthquake,the observations of gravity show：gravity variations between Shazhou（Sichuan） and Qingmuchuan（Shanxi） and Bikou（Gansu） were obvious,the amount of gravity variation is about 70×10^-8ms^-2,and the high gradient of gravity variation came into between Ningqiang（Shanxi）and Kangxian（Gansu）.The gravity variation of Wangbao line is active,the gravity variation is violent near the fault.
