Twenty years of continuous Earth observation by satellite SAR have resulted in numerous
new insights into active volcanism, including a better understanding of subsurface magma …

In areas where groundwater overexploitation occurs, land subsidence triggered by aquifer
compaction is observed, resulting in high socio-economic impacts for the affected …

Improving lava flow hazard assessment is one of the most important and challenging fields
of volcanology and has an immediate and practical impact on society. Here, we present a …

Volcanic eruptions are typically preceded by unrest, marked by increased seismicity, ground
deformation, and gas emissions. Unrest can last from decades to minutes. Accurate eruption …

Lava fountains have a major impact on the local population since they cause ash plumes
that spread several kilometers above and hundreds of kilometers away from the crater. Ash …

This work explores the properties characterizing the phase nonclosure of multilook (ML)
synthetic aperture radar (SAR) interferograms. Specifically, we study the implications of ML …

Observations from satellites provide high-resolution images of ground deformation allowing
to infer deformation sources by develo** advanced modeling of magma ascent and …

The integration of satellite data and modeling represents a step toward the next generation
of quantitative hazard assessment in response to effusive volcano eruption onset. Satellite …

Multi-temporal interferometric synthetic aperture radar (MT-InSAR) techniques are well
recognized as useful tools for detecting and monitoring Earth's surface temporal changes. In …

The gravity signal originating from magma mass movement in a volcanic conduit is retrieved
from the hydrologically disturbed absolute gravity data obtained at Asama Volcano (Central …
