2003年12月1日中哈交界Ms6.1级地震钻孔应变异常分析

2003年12月1日在中国与哈萨克斯坦交界处发生了Ms6．1级地震。震前，位于震中西南224km的新疆乌什台分量式钻孔应变仪记录到了明显的应变异常信息。经多次落实没有发现干扰，认定为是与地震有关的应变异常。认为此次异常具有应变性质，呈压性、阶段性、节律性和张、压交替变化的波动性特点。深入分析乌什台应变异常特征，总结此次地震的预测经验、教训，对以后的地震短临预测有实际意义。

Abnormal changes of crustal strain data of deep hole before Ms6.1 Earthquake on 1 December 2003

An Ms6.1 Earthquake occurred in the boundary between China and Kazakhstan on 1 December 2003. Before this earthquake, the crustal strain change information of the deep hole was recorded clearly in Wushi Seismic Station located in southwest 224km from this earthquake. The crustal strain data before the earthquake show a compressed, with interval period and rhyme scheme strain changes.
