Inferring 3D displacement time series through InSAR measurements and potential field theory in volcanic areas [PDF]
Scientific ReportsInterferometric SAR (InSAR) techniques allow the detection of ground displacements along the satellite line-of-sight (LOS) directions. Moreover, InSAR can discriminate the ground deformations along the Up-Down and East-West by combining information ...

Geodetic imaging of magma ascent through a bent and twisted dike during the Tajogaite eruption of 2021 (La Palma, Canary Islands) [PDF]
Scientific ReportsOn Sept. 19th, 2021, the largest historical eruption on the island of La Palma began, which had a significant scientific, social, and economic impact. The 2021 Tajogaite eruption was characterised by short precursors, lasting only 8 days.

Elastic interaction between Mauna Loa and Kīlauea evidenced by independent component analysis [PDF]
Scientific Reports, 2022 The contrasting dynamics between Mauna Loa and Kīlauea have been studied over the last 100 years from multiple viewpoints. The fact that dynamic changes of one volcano trigger a dynamic response of the other volcano indicates a connection may exist ...

InSAR data for monitoring land subsidence: time to think big [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Satellite interferometric synthetic aperture radar (InSAR) data have proven effective and valuable in the analysis of urban subsidence phenomena based on multi-temporal radar images.

Geophysical Research Letters, Volume 50, Issue 24, 28 December 2023., 2023 Abstract La Fossa Caldera at Vulcano (Italy) has been showing signs of unrest since September 2021. To investigate this phenomenon, we conducted an analysis of geodetic and seismological data from July to December 2021. In particular, we analyzed Multi Temporal Interferometric Synthetic Aperture Radar and Global Navigation Satellite System data ...

Near Surface Geophysics, Volume 21, Issue 5, Page 317-332, October 2023., 2023 Abstract Several methodologies allow for the detection and mapping of existing sinkholes in order to asses and manage the associated hazards and risks. These phenomena, linked to the presence of soluble rocks, are well known globally as they can cause severe damage to man‐made structures. In this paper, we propose an integrated method applied to a test‐

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 6, June 2023., 2023 Abstract Tidal salt marshes are widespread along the World's coasts, and are ecologically and economically important as they provide several valuable ecosystem services. In particular, their significant primary production, coupled with sustained vertical accretion rates, enables marshes to sequester and store large amounts of organic carbon and makes ...

Water Resources Research, Volume 59, Issue 3, March 2023., 2023 Abstract Extensive loss of salt marshes in back‐barrier tidal embayments is ongoing worldwide as a consequence of land‐use changes, wave‐driven lateral marsh erosion, and relative sea‐level rise compounded by mineral sediment starvation. However, how salt‐marsh loss affects the hydrodynamics of back‐barrier systems and feeds back into their ...

Geophysical Research Letters, Volume 49, Issue 7, 16 April 2022., 2022 Abstract We investigate the 19 September 2021 eruption of the Cumbre Vieja volcano (La Palma, Canary Islands, Spain). In particular, we analyze the Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements obtained by processing Sentinel‐1 images acquired from both ascending and descending orbits.

Automatic seismic source modeling of InSAR displacements
International Journal of Applied Earth Observations and Geoinformation, 2023 In this work we describe the implementation of a processing chain for a fully automatic modeling of the seismic source parameters and its slip distribution through the inversion of the InSAR displacements generated from the EPOSAR service.
