Dizhen xuebao, 2021 利用2014年10月至2019年9月期间欧空局Sentinel-1卫星采集的合成孔径雷达数据分析了2014年2月12日新疆于田MS7.3地震的震后形变场。结果表明，此次地震造成了南硝尔库勒断裂上明显的震后形变，首次从地震形变场的角度验证了此次地震的发震构造为NE向的左旋走滑断裂，而非部分研究所认为的近NS向断裂。由合成孔径雷达干涉测量得到的多年平均速率图显示主震的西侧仅出现了少量震后余滑且仍为强闭锁区，这意味着2008年和2014年于田两次MS7.3地震之间的区域仍存在发生强震的风险 ...

High-level collapse risk identification based on oblique photography and InSAR technology
Shuiwen dizhi gongcheng dizhi, 2023 Collapse risk identification is the basis of collapse disaster prevention. High level collapse is characterized by sudden, hidden and large height difference, which brings great challenges to information collection, disaster identification and risk ...

Using GPS as a reference frame for SAR images applied to a post eruptive period for Okmok Volcano, Aleutian Islands, Alaska [PDF]
, 2012 While high spatial coverage makes InSAR a popular tool to study active volcanoes its use can possess challenges for certain environments. Volcanoes along Alaska's Aleutian chain are difficult targets for InSAR as their seasonal snow cover causes ...

Two orders of wall‐to‐wall geographic data
Area, EarlyView.Short Abstract The use of the term ‘wall‐to‐wall’ to describe geographically extensive data without any singular definition in the remote sensing and geographically related analysis. This work presents an assessment of the application of the term in the scientific literature. Abstract From personal observations of recent published works, the term “wall‐

GPS source solution of the 2004 Parkfield earthquake [PDF]
, 2014 We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (
