| 几种烈度算法在实际震例中的对比研究 |
| |
| 摘要： 用仪器对地震烈度进行快速评估，可以在震后短时间内提供震区的灾害分布图，为震后的应急救援及灾害快速评估提供有力支持。本文研究了国内外4种常用的地震烈度评估法，结合辽宁灯塔5.1级地震获取的强震记录，对用这4种烈度算法计算的结果进行了对比。结果表明，中国仪器烈度暂行规定算法精度最高。 |

| Comparative Study of Several Intensity Algorithms Using in the Actual Earthquake |
| Abstract： With rapid assessment of instrumental intensity, disaster scatter diagram of seismic region maybe attained in several minutes, which offer strong support to rescue emergency disaster rapid assessment after earthquake. In this paper, 4 common intensity algorithms were studied and the results were compared with the records of the Liaoning Dengta M5.1 earthquake strong motion . The results show that the accuracy of the interim provisions of Chinese instrumental intensity algorithm is the highest. |
| Keywords： Intensity algorithm Strong motion observation Instrumental intensity Reliability |
