Interpretation of S-wave data from Tai’an-Xinzhou DSS profile and its relationship with Xingtai earthquakes

On the basis of S wave information from Tai’an-Xinzhou DSS profile and with reference to the results from P-wave interpretation, the 2-D structures, including S-wave velocity V _s, ratio γ between V _p and V _s; and Poisson’ s ratio σ, are calculated; the structural configuration of the profile is presented and the relevant inferences are drawn from the above results. Upwarping mantle districts (V _s≈4.30 km/s) and sloping mantle districts (V _s≈4.50 km/s) of the profile with velocity difference about −4% at the top of upper mantle are divided according to the differences of V _s, γ and σ in different media and structures, also with reference to the information of their neighbouring regions; the existence of Niujiaqiao-Dongwang high-angle ultra-crustal fault zone is reaffirmed; the properties of low and high velocity blocks (zones) including the crust-mantle transitionalzone and the boudary indicators of North China rift valley are discussed. A comprehensive study is conducted on the relation of the interpretation results with earthquakes. It is concluded that the mantle upwarps, thermal material upwells through the high-angle fault, the primary hypocenter was located at the crust-mantle juncture 30.0∼33.0 km deep, and additional stress excited the M _S=6.8 and M _S=7.2 earthquakes at specific locations around 9.0 km below Niujiaqiao-Dongwang, the earthquakes took place around the high-angle ultra-crustal fault and centered in the brittle media and rock strata with low γ and low σ values. This subject is part of the 85-907-02 key project during the “8th Five-Year Plan” from the State Science and Technology Commission.  相似文献

用远震接收函数研究滇西地区的深部结构   总被引：5，自引：1，他引：5       下载免费PDF全文

滇西地区地处欧亚板块碰撞或俯冲的边界地带，曾受到多期构造运动的影响，其地质环境和构造背景十分复杂，是我国地震活动比较活跃的地区之一. 本文选用国家、地方和流动数字台网的16个台站的远震记录. 其中PASSCAL甚宽频带流动地震台站4个，提取有效接收函数近2 000条. 两条测线的直线距离分别为650 km和450 km， 横切了滇西地区的一些主要构造单元. 研究表明，怒江断裂可能是一条具有俯冲性质的缝合线. 川滇菱形块体东西两侧的分界线¾红河断裂和小江断裂可能是直立的缝合线或碰撞带. 攀西构造带仍具有大陆裂谷的特征，即地表凹陷、上地幔隆起. 滇西地区的构造格局具有一定的规律性，造山带与缝合线相间分布. 滇西地区由北向南地壳厚度渐次减薄，S波速度整体偏低.   相似文献

田建明  徐徐  谢华章  杨云  丁政 《地震学报》2004,26(4):432-439

通过对江苏地区及南黄海海域历史地震资料特点分析，将研究区历史地震类型分为相对安全类和相对危险类，并对地震类型的统计结果、地理分布特征及构造进行探讨. 结果表明:① 江苏及南黄海地区绝大多数中强以上历史地震类型为相对安全类，仅有13.8%的中强以上历史地震为相对危险类；② 江苏陆地、长江口以东海域和南黄海北部坳陷地区以相对安全类地震为主，苏中沿海南黄海海域地震类型分布较为复杂，相对安全类和相对危险类地震类型比例基本相当；③ 研究区历史地震类型统计结果和空间分布特征与现代地震序列类型实况非常吻合，反映本区地震活动具有继承性的特点.研究结果可以作为江苏省地震应急工作中震后早期趋势判定的参考依据.   相似文献

The Frozen Soils and Devastating Characteristics of West Kunlun Mountains Pass Ms 8.1 Earthquake Area in 2001     

Chen Yongming 《中国地震研究》2004,18(4):337-347

The investigation on damages to frozen soil sites during the West Kunlun Mountains Pass earthquake with Ms 8.1 in 2001 shows that the frozen soil in the seismic area is composed mainly of moraine, alluvial deposit, diluvial deposit and lacustrine deposit with the depth varying greatly along the earthquake rupture zone. The deformation and rupture of frozen soil sites are mainly in the form of coseismic fracture zones caused by tectonic motion and fissures,liquefaction, seismic subsidence and collapse resulting from ground motion. The earthquake fracture zones on the surface are main brittle deformations, which, under the effect of sinlstral strike-slip movement, are represented by shear fissures, tensional cracks and compressive bulges. The distribution and configuration patterns of deformation and rupture such as fissures, liquefaction, seismic subsidence and landslides are all related to the ambient rock and soil conditions of the earthquake area. The distribution of earthquake damage is characterized by large-scale rupture zones, rapid intensity attenuation along the Qinghai-Xizang (Tibet) Highway, where buildings distribute and predominant effect of rock and soil conditions.  相似文献
