摘要
分析了陇南武都应变资料近10年的变化情况,发现在中国西部21世纪初的2次8级以上大地震前,陇南应变东西向、北45°西向受力元件,都经过了约2年的挤压应力增强阶段。这种震前相同的变化现象,对未来中国西部大地震发震时间的预测具有一定的参考作用。
It is analyzed Longnan Wudu strain data in recent 10 years,and found that the data of EW direction and N45° W direction were strengthened in two years before Kunlunshan Ms 8.1 earthquake and Wenchuan Ms8.0 earthquake in the western China,and their variation is helpful to predict the time of the future earthquakes in western China.
