Understanding the structure and development of calderas is crucial for predicting their
behaviour during periods of unrest and to plan geothermal and ore exploitation. Geological …

Calderas are among the most active and dangerous volcanoes. Caldera unrest is defined by
enhanced seismicity, gravity changes, surface deformation, and degassing. Although much …

The accuracy of elastic analytical solutions and numerical models, widely used in
volcanology to interpret surface ground deformation, depends heavily on the Young's …

Recent large basaltic eruptions began after only minor surface uplift and seismicity, and
resulted in caldera subsidence. In contrast, some eruptions at Galápagos Island volcanoes …

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 …

Abstract Recent advances in Global Positioning System (GPS), tilt and Interferometric
Synthetic Aperture Radar (InSAR) have greatly increased the availability of volcano …

The latest generation of synthetic aperture radar satellites produce measurements of ground
deformation at the majority of the world's subaerial active volcanoes and can be used to …

We investigate the problem of estimating magma chamber geometry using InSAR
observations of Sierra Negra Volcano, Galápagos. Ascending and descending …

Abstract The 2018 Sierra Negra eruption resulted in meter‐scale subsidence due to basaltic
magma extraction from a deflating reservoir. The eruption was also characterized by dike …

Using recent advancements in high-performance computing data assimilation to combine
satellite InSAR data with numerical models, the prolonged unrest of the Sierra Negra …
