| 摘 要： | 本文利用青海地震台网获得的观测资料对玉树地震序列的时空演化特征进行分析和研究, 结果认为Mc选取ML1.1能较好的刻画玉树地震序列的时空特征, 其地震序列在时间上呈现三个密集和衰减阶段, 在空间上具有分段集中分布的特征, 并主要分布在主震震中的西北端、 主震震中附近和主震震中东南端。 采用类比、 b值和h值等探讨了早期趋势判定问题。

| Abstract: | Temporal and spatial evolution characteristics of the 2010 Yushu M7.1 earthquake sequence have been analyzed and researched with data obtained by the Qinghai Earthquake Observation Network.The result suggests that selection of Mc=ML1.1 can better characterize the spatial and temporal characteristics of Yushu earthquake sequence.Yushu earthquake sequence shows 3 intensification and decay phases in time,and in space has a sectional concentration distribution characteristics,and mainly in the northwest of,near and the southeast of mainshock epicenter.The question of early tendency judgement of the Yushu M7.1 earthquake also has been discussed by analogy method,b value and H value. |
