通过分析１９９５年５月２日新疆乌苏５．８级地震前北天山部分跟踪台站地震波参数异常特征，特别是石场台视孕震区内地震直达波振幅比的空间分布和时序变化规律，及时发现了异常并大致判断出潜在孕震区的范围，为预报决策和动态跟踪提供了依据。文中总结了跟踪预报的过程及经验教训。 By analyzing the anomalous characteristics of the seismic wave parameters at some stations of the North Tianshan before the May 5.8 earthquake in Wusu, Xinjiang on May 2, 1995, especially the spatial distribution and timing variation of the direct-wave amplitude ratio in the quake-affected area , Discovering the anomalies in time and roughly judging the range of potential seismogenic zones provides the basis for forecasting and decision-making and dynamic tracking. The article summarizes the process of tracking and forecasting and experiences and lessons learned.
