摘要
本文以永胜地震台FSQ型浮子水管倾斜仪原始记录图形为基础,介绍了澜沧-耿马大震前后的地形变特征,探讨了大震破裂的前后过程。这些珍贵的原始记录图型,对今后该区7级以上大震的短临预报可能具有重要的参考价值。
In this paper, based on the original records by the FSQ-Model buoy water tube tiltmeter at the Yongsheng deformation station, the variational characteristics of geodetic deformation before and after the Lancang-Gengma earthquake are described. According to microfracture and stick-slip theory , the breaking process before and after the destructive great earthquake is studied. Especially, while the main fracture is impending, rock body in the focal area becames very unstable,which is a very complicated phenomenon recorded by the FSQ tiltmeter. The precious original records could have some important reference value for the short-term and impending earthquake(M≥7.0)prediction in the area.
