摘要: 用加卸载响应比理论对华南地区12例中强以上地震进行研究, 结果表明有8例在震前响应比值有明显的高值( Y≥ 2. 0)异常显示, 通过对响应比值随时间变化特征的分析表明, 响应比对5级左右地震有较好的中短期预测效果, 因此响应比理论可作为华南地区地震预测方法。

Abstract: The variation characteristic of the load-unload responseratio with time before 12MS≥ 4. 2 earthquakes distributing in the South China area are studied by using the loadunload response ratio theory. There sult shows that before 8 of 12 earthquake case, obvious anomalous response ratio appeared high-value changes. There are 5-17 months from the moment of the maximum value to earthquake occurrence, we consider that the loadunload response ratio is a useful method to estimate the earthquake occurrence in the South China area.

Key words: Response ration, Earthquake prediction, South China area
