| 摘 要： | 将海南岛及其近海的地震应变能作为响应因子,对该地区的中强以上的地震在震前的加卸载响应比异常特征进行了分析和研究,认为地震前的加卸载响应比异常是该地区中期或者短期的前兆异常,为该地区中短期地震监测和预报提供了一种手段。 |
| 关 键 词： | 加卸载响应比 地震预报 海南岛 |

| Abstract: | Using the seismic strain energy as the response factor,the anomalous characteristics of Load/Unload Response Ratio before moderate-strong earthquakes in Hainan Island and its adjacent area are analysed. The research result indicates that the high anomaly of LURR is a kind of medium-term and short-term precursor before moderate-strong earthquake in this region. It could be a new method for earthquake prediction. |
| Keywords: | Load/Unload response ratio Earthquake prediction Hainan Island |
