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.

该项目的冰岛火山火山台上火山地面变形的动态毛弹性数值分析是使用新的动态，毛弹性连续机械力学火山变形模型来重现冰岛目标火山的观察到的变形，并更加稳健，更真实地约束Magma的供应和存储特性。我们将定制现有理论模型的参数，以通过合并独立的地质，地球化学，岩土技术和地球物理数据来建模的特定冰岛火山。地球化学数据将包括岩浆流变学和熔体结晶度等参数。地球物理和岩土技术将包括异质机械性能（密度，杨氏模量，剪切强度等），数字高度模型的表面形貌以及以前通过地球物理成像来推断的岩浆储层几何形状。
