中国大陆地壳运动观测研究进展
|
摘要
本文利用国家重大科技基础设施"中国大陆构造环境监测网络"1972个站两期GNSS观测资料绘制2009—2011年中国大陆地壳运动图。该图反映了2011东日本大地震同震形变对我国东部地壳运动及变形状态的巨大影响,也反映2008汶川地震和2001昆仑山口西地震震后变形对青藏高原构造应力场的调整过程,较为完整地展示印度板块挤压下青藏高原的变形状态。
We present the most recent crustal displacements in China,based on two GNSS observation campaigns in 2009 and 2011 at 1972 sites of the national major scientific infrastructure project "Crustal Movement Observation Network of China"(CMONOC).The displacement map shows the far-field effects of the 2011 Tohoku earthquake on stress-field of northeast China,as well as postseismic deformation associated with the 2001 Kunlun Shan and the 2008 Wenchuan earthquakes,and it also displays the current deformation of the Tibetan Plateau due to the indention of the Indian plate in unprecedented details.
