Volcano deformation analysis in the Lazufre area (central Andes) using geodetic and geological observations
Large-scale volcanic deformation recently detected by radar interferometry (InSAR) provides new information and thus new scientific challenges for understanding volcano-tectonic activity and magmatic systems. The destabilization of such a system at depth noticeably affects the surrounding …

Dynamic Poroelastic Finite Element Deformation Modelling of the Bárðarbunga Volcano, Iceland, 2015-2024
Monitoring and modelling of ground deformation at volcanoes provides key insights into how a subsurface magmatic system is evolving due to magma movements at depth. Here, we present a dynamic poroelastic-reservoir Finite Element (FE) volcano deformation model. This thesis aims to reproduce the …

A Geophysical Survey Of Active Volcanism In The Central And Southern Andes
… allow further examination of selected volcanoes. I establish the first catalog of seismicity at Uturuncu volcano in Bolivia, where InSAR has observed continuous uplift since 1992, and find an unusually high seismicity rate for a Pleistocene volcano as well as swarm activity and …

Towards monitoring volcanoes in Iceland and Hawai’i with seismic velocity variations
… is an exciting technique for studying volcanoes because it provides a continuous measurement of relative seismic velocity (dv/v), which is sensitive to magmatic processes that affect the physical properties of the surrounding crust. However, understanding the causal mechanisms …
