澜沧—耿马地震前FSQ仪记录到的粘滑和慢地震及对短临预报探讨

STICK-SLIP AND SLOW SHOCKS RECORDED ON FSQ TILTMETERS BEFORE LANCANG-GENGMA EARTHQUAKE AND PRIMARY STUDY ON SHORT-IMPENDING EARTHQUAKE PREDICTION

本文分析了弥渡、永胜、楚雄台ＦＳＱ型浮子水管仪原始记录图，发现澜沧一耿马大震前，出现短临形变异常特征，其主要表现为粘滑、慢地震。粘滑、慢地震、小震活动是大震前震源体直接传播出来的孕震过程的主要信息。及时分析定点形变台站观测中的这些震兆信息，可能是探索短临地震预报的一种良好途径。

After analysing original recording registered on FSQ Floating Water-tube Tiltmeters in Midu,Yongsheng and Chuxiong stations,short-impending deformation anomalies discovered show stick-slip and slow shocks.Stick-slip,slow shocks and minor seismicity are the major earthquake process information from the seismic body before a great earthquake.Analysing the precursors observed on fixed deformation stations on time probably is a good way to study short-impending earthquake prediction.
