| 摘 要： | 2006年7月18和19日在青海玉树相继发生了5.0、5.6和5.4级地震。本文通过玉树地震台记录的地震波形及青海省地震台网监测结果分析该地震事件属于震群型地震;通过现场考察及宏观烈度区、余震分布和震源机制解、区域构造分析认为发震构造为乌兰乌拉湖-玉树构造带。 |
| 关 键 词： | 玉树地震 震群型地震 发震构造 |

| Abstract: | Three earthquakes with MS5.0,MS5.6 and MS5.4 occurred on July 18,19,2006,in Yushu prefecture of Qinghai province.In this paper the event is determined as a earthquake swarm based on the waveforms recorded by Yushu seismic station and monitoring result from Digital Seismic Monitoring Network of Qinghai province.Synthesizing the seismic intensity isogram,distribution of aftershocks,focus mechanism and regional tectonics,the seismogenic fault of this earthquake is considered as Wulanwula lake-Yushu structure belt. |
| Keywords: | Yushu earthquake Seismic type of earhquake swarm Seismogenic structure |
