InSAR tropospheric correction combining GNSS data and a global atmospheric model

Revue Française de Photogrammétrie et de Télédétection, 2018
Les mesures issues de l'interférométrie d'images radar (InSAR), notamment satellitales, doivent être corrigées du délai dû à la propagation des ondes dans l'atmosphère. Plusieurs travaux ont déjà montré l'intérêt de cette correction. Cet article présente

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

International Journal of Climatology, Volume 46, Issue 11, September 2026.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

Newspaper reporting of the April 2007 eruption of Piton de la Fournaise part 1: useful information or tabloid sensationalism?

Journal of Applied Volcanology, 2018
During March, April and May 2007 the local newspaper for the island of La Réunion, “Le Journal de L’Ile de La Réunion” (JIR), published 427 articles relating to natural hazards, with hazard-related articles occupying a total paper area of 21.94 m2 and ...

Repetitive small seismicity coupled with rainfall can trigger large slope instabilities on metastable volcanic edifices

Communications Earth & Environment, 2023
Quantifying the effect of external forcings like seismicity or rain on slope destabilization is a long-standing and challenging issue. To investigate the respective roles of these forcings, we analyze an unprecedented 10-year long catalog of rockfalls ...

Combining hydro-acoustic sources and bathymetric differences to track the vent evolution of the Mayotte eruption, Mozambique Channel

Frontiers in Earth Science, 2022
The majority of Earth volcanism takes place in the deep ocean. Deep-sea volcanoes are particularly complicated to study due to their remoteness. Very different methods can be used and their combination can lead to crucial information about submarine ...

Pressurization of Shallow Magma Reservoir Preceding Basaltic Eruptions at an Open‐Vent Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Open‐vent volcanoes are characterized by the persistent activity of outgassing, lava effusion and mild explosions, which is, however, occasionally interrupted by more violent explosive activity (paroxysm), for example, Stromboli (Italy). In spite of the different (two orders of magnitude) explosive intensities and different petrological magma ...

Eruptive pattern classification on Mount Etna (Sicily) and Piton de la Fournaise (La Réunion)

, 2016
In the framework of the European MEDiterrranean Supersite Volcanoes (MEDSUV) project, Mt. Etna (Italy) and Piton de la Fournaise (La Réunion) were chosen as “European Supersite Demonstrator” and test site, respectively, to promote the transfer and ...

360 Intrusions in a Miniature Volcano: Birth, Growth, and Evolution of an Analog Edifice

Frontiers in Earth Science, 2019
Most volcanoes throughout the world have been monitored with geophysical data (seismology and geodesy) for no more than three decades, a relatively short time compared to their overall life.

The August 2019 Piton de la Fournaise (La Réunion Island) Eruption: Analysis of the Multi-Source Deformation Pattern Detected through Sentinel-1 DInSAR Measurements

Remote Sensing, 2022
Piton de la Fournaise is one of the most active worldwide volcanoes, located on the southeastern part of La Réunion Island. In this work, we focus on the eruption that occurred on the southeastern flank of this volcano, inside the Enclos Fouqué caldera ...

InSAR Evidence of Small‐Scale Faults Activated During Rift Zone Intrusions at Piton de la Fournaise Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Volcanic edifices show complex internal structures including discontinuities at different scales. These discontinuities can act as zones of weakness and are closely linked to volcanic activity distribution and associated hazards, making their detection and monitoring essential. In this study we investigate the presence of small‐scale faults on
