Source Model for Sabancaya Volcano Constrained by DInSAR and GNSS Surface Deformation Observation
Remote Sensing, 2020 Sabancaya is the most active volcano of the Ampato-Sabancaya Volcanic Complex (ASVC) in southern Perú and has been erupting since 2016. The analysis of ascending and descending Sentinel-1 orbits (DInSAR) and Global Navigation Satellite System (GNSS ...

Volcano deformation monitoring using GPS [PDF]
Journal of Spatial Science, 2007 Volcanic eruptions are often very destructive events, having a massive impact on the natural and human environment. In order to mitigate the effect of volcanic hazards such as pyroclastic flows, lahars and tsunamis it is necessary to closely monitor volcanoes. Ground surface deformation is recognised as a reliable indicator of an impending eruption and

Frontiers in Earth Science, 2021 A key issue on active volcanoes is to investigate the position and characteristics of the magma reservoirs over time. The aim is to better understand the crustal magma transfer, therefore also to define the volcanic hazard and plan the mitigation ...

Ground deformation before the 2015 eruptions of Cotopaxi volcano detected by InSAR
Geophysical Research Letters, 2017 Cotopaxi volcano started a period of volcanic unrest in April 2015 that led to a series of eruptions between August and November 2015. We use COSMO‐SkyMed Interferometric Synthetic Aperture Radar supported by continuous GPS observations spanning the ...

Topography and structural heterogeneities in surface ground deformation: a simulation test for Somma-Vesuvius volcano [PDF]
Advances in Geosciences, 2021 We simulate the deformation of Somma-Vesuvius volcano due to some overpressure sources by means of a finite element 3D code. The main goal of these simulations is to investigate the influence of topography and structural heterogeneity on ground ...

Global Volcano Monitoring: What Does It Mean When Volcanoes Deform? [PDF]
Elements, 2017 Currently, it is only possible to look inside an active volcano using indirect geophysical methods. One such method is to measure surface deformation, which results from subsurface magmatic or hydrothermal processes. Modern satellite data allows deformation to be measured at hundreds of volcanoes without relying on limited ground instrumentation.
