摘要
自1927年以来,库尔勒地区Ms≥5.0级地震有平均10年左右的活动周期。1988年5月26日5.2级地震前,存在地震空区、条带、应变释放偏低等测震学前兆,形变、应力、地电、泉水流量等多项前兆观测均有不同程度的中期和短临异常显示。
The earthquakes (Ms≥5.0) occurred in Kuerle region have shown an active period about ten years since 1972. Some obvious seismometric precursors such as seismic gap and strip, reduced strain release and something else appeared before Kuerle earthquake of magnitude 5.2 on May 26, 1988. Meanwhile, some mid-short term anomalous changes of ground deformation, stress observation, geoelectric resistivity and discharge of the springs etc. were also showed in various degrees.
