兴都库什-帕米尔地区与天山地震带强震活动关联分析
|
摘要
首先通过对区域地质构造背景、地震活动性质以及动力环境等的分析,认为天山地震带强震活动主要受兴都库什-帕米尔构造结的动力控制。其次分析了兴都库什-帕米尔地区与天山地震带强震活动之间的相关关系,结果表明两地区强震成组活动存在一定的同步特征;进一步考察兴都库什-帕米尔地区中源地震与天山地震带强震活动之间关系,发现两者同样存在同步特征,且该区中源地震的活动强度和频度越大,天山地震带的强震活动越剧烈,其分布范围也越广。该结果从地震活动的角度反映了兴都库什-帕米尔地区对天山地震带强震活动的动力控制作用。
In this paper, we introduce the geological structure, focal mechanisms of historical earthquakes and geodynamic setting of Tienshan and its neighboring region, and draw a conclusion of the large earthquakes in the Tienshan seismic zone governed mainly by the pushing from Hindu Kush-Pamir syntax. We then investigate the relationship of large earthquakes in the Hindu Kush-Pamir and Tienshan seismic zone, and find the synchronization features is existing in grouped large earthquakes between the two regions. The relationship of intermediate-focus large earthquakes in Hindu Kush-Pamir and shallow large earthquakes in Tienshan seismic zone is also discussed. The same synchronization characteristics is also found between the two, and the intensity and frequency of intermediate-focus earthquakes is fiercer. Large earthquakes in the Tienshan seismic zone are more intense, and the distribution range is also wider. The above results confirm the geodynamic correlativity between the Hindu Kush-Pamir and the Tienshan seismic zone from the viewpoint of seismicity.
