摘要
昆仑山口西8.1级地震前华北地区的重力场发生了明显的异常变化,说明在较大地震之前可以出现较大范围的反映明显的前兆异常(场兆).目前华北地区重力场的异常变化仍然存在,可能意味着西部仍有发生7～8级地震的可能性.
Significantly anomalous variation of gravity field in Northern China occurred before M8.1 earthquake at west to Kunlun Mountain Pass.It may shows that obvious precursors(fieldprecursor)could take place in broad extent before a strong earthquake.In present time the anomalous variation of gravity field still exists in Northern China region,may imply the next M7～8 earthquake in western China.
