Dynamic Poroelastic Numerical Analysis Of Volcano Ground Deformation At Icelandic Volcanoes (Ref: 4659)

冰岛火山地表变形的动态孔隙弹性数值分析本项目的目的是利用新的动态、孔隙弹性连续力学火山变形模型来重现冰岛目标火山的观测变形，从而更稳健、更真实地约束岩浆供应和储存特征。我们将结合独立的地质、地球化学、岩土和地球物理数据，将现有理论模型的参数调整为冰岛火山的具体模型。地球化学数据将包括岩浆流变学和熔体结晶度等参数。地球物理和岩土工程数据将包括非均质力学特性（密度、杨氏模量、抗剪强度等）、数字高程模型的地表地形，以及以前通过地球物理成像推断出的岩浆储层几何形状。

Dynamic Poroelastic Numerical Analysis Of Volcano Ground Deformation At Icelandic VolcanoesThe aim of this project is to use new dynamic, poroelastic continuum-mechanics volcano deformation models to reproduce observed deformation at Icelandic target volcanoes and more robustly and realistically constrain magma supply and storage characteristics. We will tailor the parameters of existing theoretical models to the specific Icelandic volcanoes being modelled by incorporating independent geological, geochemical, geotechnical and geophysical data. Geochemical data will include parameters such as magma rheology and melt crystallinity. Geophysical and geotechnical data will include heterogeneous mechanical properties (density, Young's Modulus, shear strength, etc.), surface topography from digital elevation models, and magma reservoir geometries that have previously been inferred through geophysical imaging.
