【摘要】 本文对剑川、禄劝和石屏地震前后所进行的流动重力测量作了分析研究。结果表明:在±20—±25微伽精度范围内,震中距测线6—60公里的情况下,剑川、禄劝地震前后均未出现明显的重力异常变化。石屏地震前近东西走向的扬武—石屏测线剖面有一些趋势性重力变化。更多还原

【Abstract】 This paper has analysed and studied the mobile gravitational measurements data made before and after the Jianchuan, Luquan and Shiping earthquakes. The result shows that gravitational anomalous variations didn’t appear before and after the Jianchuan and Luquan earthquakes under the conditions that the observational lines are six to sixty km from the epicenters and the observational accuracy was from ±20-±25 microgals. Some gravitational tendency variations have beenobserved on the EW Yangwu-Shiping observational line profile prior to the Shiping earthquake.更多还原
