Linking precursory volcano deformation to eruptive activity using satellite InSAR

这项研究将集中在美国地质勘探局感兴趣的火山观测到的局部变形模式。这些火山在过去的几十年里表现出不同程度的火山活动。必须了解可观测到的地表变形与地下过程之间的联系，以便在必要时有效地采取减缓措施。高分辨率卫星合成孔径雷达数据的到来使全球火山监测达到了前所未有的规模。通过这项研究，我的目标是进一步发展我们利用这些数据预测火山爆发和确定相关自然灾害的能力。几个卫星数据集的使用允许近实时监测全球火山开放的可能性，以创建一个自动的火山变形检测系统，这是有用的火山有限的，没有现场的表面变形数据收集。在可能的情况下，我认为这是重要的是连接从SAR卫星观测到的表面变形地面观测。这些地面观测通常具有更好的时间分辨率，使我们能够更详细地了解感兴趣的火山的动态性质。此外，这些地面观测可用于验证卫星SAR数据集。

This research will focus on the localized deformation patterns observed at the volcanoes of interest to the USGS. These volcanoes have overthe past decades expressed varying levels of volcanic activity. The link between the observable surface deformation and the subsurfaceprocesses is important to understand in order to effectively emplace mitigation measures where necessary. The arrival of high-resolutionsatellite SAR data allows for global volcano monitoring at an unprecedented scale.With this research, I aim to further develop our ability to use this data to predict volcanic eruptions and identify related natural hazards. Theuse of several satellite data sets allows for near real-time monitoring of volcanoes globally which opens up the possibility to create anautomatic volcano deformation detection system which is useful for volcanoes with limited on no in-situ surface deformation data collection.Where possible, I think it is important to link the observed surface deformation from the SAR satellites to ground observations. The groundobservations often have a better temporal resolution allowing us to understand the dynamic nature of the volcanoes of interest to greater detail.Additionally, these ground observations can be used for validation of the satellite SAR datasets.
