中文摘要
该项目是2015年4月25日尼泊尔发生7.9级地震后部署临时地震台网的一项快速行动。项目期间收集的数据将在阵列拆除一个月后公开提供给地震学界。这些数据收集影响了喜马拉雅地区以其巨大的地震危险而闻名。在2015年地震地区部署余震将使地震学家能够进行研究,这将增加我们对喜马拉雅主逆冲的行为的理解,这是一个主要的地下断层,造成了这次地震和喜马拉雅地区其他历史上的破坏性地震。在这个项目中,25个地震台站将部署在2015年4月25日地震的大震中地区,以及尼泊尔西部,那里有一个长期存在的裂缝,自1505年最后一次破裂以来,已经积累了大约10米的滑动赤字。这些数据将特别有助于确定2015年地震的良好约束震源模型,定义喜马拉雅主逆冲构造的几何形状,并分析震后变形与余震之间的关系。这一部署将与美国大学的另一项快速部署密切协调,该部署将增加20个地震台站,这将增加监测网络的规模。
英文摘要
This project is a rapid action to deploy a temporary seismological network following the Mw 7.9 earthquake of April 25, 2015 in Nepal. Data collected during the project will be made openly available to the seismological community one month after the array is uninstalled. This data collection impacts the Himalayan region known for its great seismological hazard. Aftershock deployment in the area of the 2015 earthquake will enable seismologists to conduct research, which will increase our understanding of the behavior of the Main Himalayan Thrust, a major underground fault responsible of this and other historical destructive earthquakes in the Himalayan region.In this project 25 seismic stations will be deployed in the greater epicentral region of the April 25, 2015 earthquake, and in western Nepal where a long-standing gap has accumulated about 10 m of deficit of slip since it last ruptured in 1505. These data will be useful in particular to determine a well-constrained source model of the 2015 earthquake, define the geometry of the Main Himalayan thrust, and analyze the relationship between post-seismic deformation and aftershocks. This deployment will be closely coordinated with another rapid deployment by US universities with 20 additional seismic stations that will increase the size of the monitoring network.
