| 摘 要： | 利用全球27个水库诱发地震的烈度资料，研究水库诱发地震的烈度衰减规律, 结果表明:与同震级的构造地震相比，低震级时，水库诱发地震的烈度明显偏高，随着震级 升高，与构造地震烈度的差距逐渐减小;水库诱发地震还具有震源浅、衰减快、影响范围小的特点。

| Abstract: | By use of the intensity meterials of 27 reservoir induced earthquakes in the world, the intensity attenuation laws of reservoir induced earthquakes were investigated, and it is concluded that,in comparison with tectonic earthquake, the intensity of reservoir induced earthquakes at low magnitude was higher than that of the tectonic earthquake. The large of the magnitude,the smaller of the difference between the intensities. In addition, reservoir induced earthquakes have more characteristics such as shallower focus,quicker attenuation,and smaller influence area. |

| Keywords: | intensity attenuation reservoir- induced earthquake earthquake focus linear regression |
