Research fields

Volcano deformation

We study ground deformation associated with volcanic activity using both space-based and ground-based monitoring systems, including InSAR, image correlation, pixel offsets and change detection. We also develop new tools for deriving and analysing precise deformation time series, with a particular focus on improving data availability and volcano monitoring in remote regions that are difficult to access.

Earthquake deformation

Geodetic measurements of earthquakes, acquired from both satellite and ground-based systems, help improve our physical understanding of the processes that lead to and accompany tectonic and volcanotectonic earthquakes.

Volcano and earthquake modelling

Using analytical and numerical models, we investigate near-surface, endogenous, and deep-seated processes in both volcanic and non-volcanic environments. By inverting deformation data, we obtain detailed information on the location and volume changes of magmatic reservoirs and better constrain the complex geometry of dikes, sills, and magma chambers. We also use boundary element and finite element modelling to explore the effects of material heterogeneity, non-linear rheology, and complex geometries. In addition, analogue experiments help us visualise and better understand dynamic geological processes, such as caldera collapse.

Volcano hazard and early warning

Our research contributes to the assessment of volcanic hazards related to deformation, magma intrusion, and eruption, and supports the development of early warning systems. We analyse deformation time series from both satellite and ground-based observations to detect changes that are significant for accurate evaluation of volcanic activity. For example, we estimate the likely locations of future eruptions and investigate how volcanic products may influence patterns of earthquake damage.
