Quantifying sediment supply to the river from a tropical slow-moving landslide using photogrammetry: the case study of Grand Eboulis, Réunion Island Open
Landslides, in general, can release large volumes of sediment into rivers, sometimes causing river blockages, outburst floods, or mudflows. Quantifying sediment contributions from landslides is important not only for the resilient developm…

Impact of climate and volcanism age on landscape evolution of oceanic islands Open
Tropical hotspot volcanic islands are exceptional laboratories for understanding climate-landscape interactions. Réunion Island, in the southern Indian Ocean, is particularly interesting because it has one of the largest rainfall grad…

Insights on Denudation Controls of Volcanic Tropical Islands from Meteoric 10Be/9Be Ratios Open
Weathering of volcanic rocks accounts for approximately one third of global CO2 consumption in the silicate weathering cycle1. Tropical volcanic islands contribute to this process due to their extreme denudation rates, thought to be mainly…

Evidence for Erosional Efficiency of Extreme Precipitation Events at a Multi‐ Decadal Time Scale Open
Extreme precipitation events play a pivotal role in shaping Earth's surface through their influences on hillslope processes (triggering mass‐wasting events) and on transport capacity and dynamics of rivers. This study investigates the impa…

Evidence for Erosional Efficiency of Extreme Precipitation Events at a Multi-Decennial Time Scale Open
Extreme precipitation events play a pivotal role in shaping Earth’s surface through their influences on hillslope processes and sediment transport in rivers. In this study, we focus on understanding the implications of such events on sedim…

Enhanced CO2 consumption rate from silicate weathering by landslide erosion in the volcanic island Open
Silicate weathering plays an important role in sequestering CO2 over geological time scales. Physical erosion is an important process of mineral surface production, significantly promoting efficient chemical weathering. Landslides, in part…

Dynamics and controls of a tropical slow moving landslide measured by remote sensing: the study case of Grand Éboulis, Réunion Island.  Open
Landslides are efficient erosion processes that release large volumes of sediments in rivers, posing threats to nearby population when remobilised during large flood events. Thus, understanding the dynamics and controls of landslides and q…

River incision on hotspot volcanoes: insights from paleotopographic reconstructions and numerical modelling Open
The influence of climate on landscape evolution in natural settings remains debated. Here, we focus on tropical hotspot volcanic islands because they exhibit relatively uniform lithology and experience significant precipitation and climate…

Linking Dynamic Water Storage and Subsurface Geochemical Structure Using High‐Frequency Concentration‐Discharge Records Open
Shifts in water fluxes and chemical heterogeneity through catchments combine to dictate stream solute export from the Critical Zone. The ways in which these factors emerge in resultant concentration‐discharge ( C‐Q ) relationships remain o…

The 1965 Mahavel Landslide (Réunion Island, Indian Ocean): Morphology, Volumes, Flow Dynamics, and Causes of a Rock Avalanche in Tropical Setting Open
In May 1965, a main landslide occurred in a deeply incised valley of Piton de la Fournaise volcano, in Réunion Island. This event occurred one day after heavy rainfalls and was consequently interpreted as a mud/debris flow. We take advanta…
