摘要/Abstract

摘要： 应用多台和达法计算了2006年 2月 4日至4月3日发生在温州珊溪水库地区M_L≥2.0地震的平均波速比。计算使用高质量的数字地震记录, 在较强地震前观察到持续的低值异常现象, 在时间分布上出现较明显的异常过程: 下降—持续异常—回升—发震, 分析表明异常变化结果可信。

关键词: 多台和达法, 平均波速比, 低值异常, 温州珊溪水库

Abstract: Using the multi-station methods we calculated the seismic wave velocity ratio for earthquakes(M_L≥2.0) occurred from February 4, 2006 to April 3, 2006.Using the high molar figure seismic events, the results show that distinct low value anomalies of seismic velocity ratio before the strong earthquakes. The course of distinct low value anomalies of seismic wave velocity ratio is decline—sustained anomaly—recovery—occurrence. The analytical result indicates that the anomaly result is credible.

Key words: Multi-station method, Average wave velocity ratio, Low value anomaly, Shanxi reservoir of Wenzhou
