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 impact of such events on sediment transport using Réunion Island as a natural laboratory due to its intense tropical rainfall regime. Through photogrammetric techniques using historical aerial images, we reconstructed nine DEMs of the entire canyon bed of the ephemeral Rivière des Remparts spanning six decades. Based on differences in DEMs and sediment volume estimates combined with cosmogenic 3 He measurements, we assessed the spatio-temporal evolution of the entire canyon bed and the drainage of products from major landslides and rock avalanches between 1950 and 2011. Results indicate that 50.2 ± 8.4 Mm 3 (145.5 ± 24.4 Mt) of sediment was transported out of the watershed over 62 years via bed load waves. We modeled the flow dates and showed that such an export of material occurred during only 391 days over the 62 years, at an average rate of 0.13 ± 0.02 Mm 3 /day (0.37 ± 0.06 Mt/day). Our investigation confirms that sediment transport coincides with officially recorded extreme meteorological events such as cyclones. Moreover, our findings reveal that sediment transport predominantly occurs on days corresponding to highpercentile rank precipitation events, demonstrating that all transport is concentrated during these intense rainfall periods. Finally, we underscore the extremely fast conveyance of material from slopes to deep-sea fans, facilitated in Réunion by the absence of a coastal platform.

abstract PDF url

A massive inversion of the Hapke model is carried out over the Asal-Ghoubbet rift (Republic of Djibouti) using high-resolution multiangular Pleiades images. This is the first time that such an inversion is performed on Earth over an entire image, previous studies having focused on planetary surfaces. This work addresses challenges such as atmospheric and geometrical corrections of these images to produce parameter maps. The use of fast Bayesian inversion significantly reduces computation times thanks to efficient exploration of the parameter space and leads to improved prediction. The parameters of the Hapke model are also interpreted in terms of surface physical properties, thanks to field measurements. Single scattering albedo is the parameter extracted with the greatest reliability, although its validation is still difficult due to the absence of a simple formula linking it to surface reflectance. Our study reveals a close relationship between photometric roughness and single scattering albedo, indicating that accurate extraction of the former is highly dependent on values of the latter, which must be below 0.8 for reliable estimation. Finally, the correlation between phase function parameters and grain properties depends on surface type and material properties.

Climate change is increasingly predisposing polar regions to large landslides. Tsunamigenic landslides have occurred recently in Greenland (Kalaallit Nunaat), but none have been reported from the eastern fjords. In September 2023, we detected the start of a 9-day-long, global 10.88-millihertz (92-second) monochromatic very-long-period (VLP) seismic signal, originating from East Greenland. In this study, we demonstrate how this event started with a glacial thinning–induced rock-ice avalanche of 25 × 10^6 cubic meters plunging into Dickson Fjord, triggering a 200-meter-high tsunami. Simulations show that the tsunami stabilized into a 7-meter-high long-duration seiche with a frequency (11.45 millihertz) and slow amplitude decay that were nearly identical to the seismic signal. An oscillating, fjord-transverse single force with a maximum amplitude of 5 × 10^11 newtons reproduced the seismic amplitudes and their radiation pattern relative to the fjord, demonstrating how a seiche directly caused the 9-day-long seismic signal. Our findings highlight how climate change is causing cascading, hazardous feedbacks between the cryosphere, hydrosphere, and lithosphere.
Possibly seismically triggered avalanches after the S1222a Marsquake and S1000a impact event

Ground motion from seismic events detected by the SEIS/InSight seismometer on Mars could potentially trigger dust avalanches. Our research strongly suggests that the seismic event S1000a may have triggered a significant number of dust avalanches. In contrast, following the seismic event S1222a, there was only a modest increase in avalanche occurrences. Orbital observations of the area surrounding the projected location of the S1222a quake reveal notable topographic features, such as North-South ridges and impact craters. We utilize orbital imagery to evaluate the rate of avalanches and explore how the S1222a event might have influenced this rate. The S1222a event appears to be a plausible factor contributing to the observed increase in avalanches. Our further analysis of the epicenter location aims to clarify how it aligns with the avalanches’ spatial distribution, offering insights into the regional topography.

The 1965 Mahavel Landslide (Réunion Island, Indian Ocean): Morphology, Volumes, Flow Dynamics, and Causes of a Rock Avalanche in Tropical Setting

Laurent Michon, Eric Gayer, Antoine Lucas, Franziska Bellin, and Matthieu Gougeon

Journal of Geophysical Research: Earth Surface, 2023.

abstract PDF url

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 advantage of several sets of historical photographs to reappraise this event. They show that the collapse of a large part of the valley headwall produced a rock flow that dropped 1,740 m and traveled 5,050 m. The surface morphology suggests that the landslide produced a main flow that evolved in a secondary flow in the distal part. The main flow deposit is composed of a matrix-rich fragmented facies and a jigsaw-fracturated facies. The matrix presents a gravely-to-silty granulometry and fractal dimensions ranging between 2.472 and 2.865. Volumes of the collapsed material (59.7 ± 3.1 Mm3) and the deposit (46 ± 13 Mm3) were determined from a photogrammetric approach. We estimated velocities ranging between 86 and 44 m s−1 along the flow path. Our simulations with SHALTOP reveal that the landslide geometry and velocities are well reproduced with frictional Coulomb rheology. We thus interpret the 1965 Mahavel landslide as a main rock avalanche rather than a mud/debris flow. We propose that the trigger of the 1965 avalanche, and of the smaller events in 1995 and 2001, is the water infiltration related to the intense rainfalls, which systematically preceded by one day each collapse. Finally, the succession of dry and wet years before each collapse event could promote favorable conditions to failure.
Phenomenological model of suspended sediment transport in a small catchment

Earth Surface Dynamics, 2023.

abstract PDF url

We develop a phenomenological model of suspended sediment transport on the basis of data acquired in the Capesterre river, which drains a small tropical catchment in Guadeloupe. The model correctly represents the concentration of suspended sediment during floods, provided that the relation between concentration and water level forms a counterclockwise loop. In the model, the properties of the sediment and of the river are all lumped into four parameters: a settling velocity related to the size of the suspended sediment, a threshold water level which acts as a proxy for the threshold shear stress, a characteristic entrainment rate, and a dimensionless exponent. The value of the parameters changes from one flood to the next, probably reflecting changes in the characteristics of the river and the fine sediment. Finally, a test of the model against data acquired in a small catchment in the French Alps suggests that the model is versatile enough to be used in diverse hydrological settings.

Decennial geomorphic transport from archived time series digital elevation models: a cookbook for tropical and alpine environments

Antoine Lucas, and Eric Gayer

IEEE geoscience and remote sensing magazine, 2022.

abstract PDF url

On the seasonal timescale, for accessible locations and when manpower is available, direct observations and field surveys are the most useful and standard approaches. However very limited studies have been conducted through direct examination on decennial-to-century timescales due to observational constrains. Here, we present an open and reproducible pipeline based on historical aerial images (across a timeline of up to 70 years) that includes sensor calibration, dense matching, and elevation reconstruction in two areas of interest that represent pristine examples of tropical and alpine environments. The Remparts and Langevin rivers, on Réunion Island, and the Bossons glacier, in the French Alps, share limited accessibility (in time and space) that can be overcome only by remote sensing. We reach a metric-to-submetric resolution close to the nominal image spatial sampling. This provides elevation time series with better resolution than most recent satellite images, such as Pleiades, in a decennial time period.

Enigmatically, some landslides flow farther than normal frictional resistance allows. Cassini images of Saturn’s icy moon Iapetus reveal a multitude of long-runout landslides that may have been enabled by flash heating along the sliding surface.

EN: Slope instabilities take part in weathering and transport processes at the surface. The runout distance is extensively used in analysis of landslide dynamics and in the calibration of the rheological parameters involved in numerical modelling. However, the unknown impact of the uncertainty in the shape of the initial released mass on the runout distance and on the overall shape of the deposit questions the relevance of these approaches. Indeed, the shape of the initial scar is generally unknown in real cases. Our study is based on numerical simulations coupled with remote sensing data analysis. The model used in this study has been intensively compared with laboratory experiments and well constrained natural cases in order to establish its range of use. We have also developed a pre-event topographic reconstruction method using remote sensing data allowing the study of the topographic and initial failure plane geometry effects. We show that the runout distance is a robust parameter that is only poorly affected by the initial scar geometry. On the contrary, the extent of the deposits perpendicular to the main mass displacement direction is shown to be controlled by the scar geometry, providing a unique tool to retrieve information of the initial failure geometry, as well as on the released volume. A feedback analysis of Martian landslides shows excellent agreement between numerical results and geomorphological evidence, providing insight into the initial landsliding conditions. In addition, we introduce a new empirical dissipation parameter allowing a good prediction of the runout in the simulation without any calibration for a given geological context. FR: Les instabilités gravitaires contribuent aux processus de transport de matière à la surface des planètes et constituent des risques importants pour les populations sur Terre. Afin d’apporter des contraintes sur la dynamique des instabilités gravitaires, notre étude se base sur le couplage entre simulation numérique et analyse des données par télédétection. Le modèle utilisé s’est montré capable de reproduire des ob- servations en laboratoire ainsi que la dynamique enregistrée par des signaux sismiques pour un exemple terrestre. En outre, nous avons développé une méthode de reconstruction topographique pré-glissement en utilisant les données satellitaires afin d’étudier les effets des conditions initiales. En effet, la distance d’arrêt (runout) des dépôts est très largement utilisée dans l’analyse de la dynamique des glissements de terrain ainsi que dans la calibration des paramètres rhéologiques impliqués dans la modélisation, et ce malgré les incertitudes sur la géométrie initiale. Nous montrons par des tests théoriques que le runout est faiblement affecté par la géométrie du plan de rupture. Au contraire, l’extension latérale se révèle être contrôlée par la géométrie initiale ce qui fourni un cadre unique pour remonter également au volume initial. L’application aux exemples martiens apporte des contraintes sur les conditions de mise en place et ouvre de nouvelles perspectives pour la compréhension de la dynamique de ces processus. En outre, nous introduisons un nouveau paramètre de dissipation empirique indépendant de la topographie permettant, sans calibration, de retrouver par la simulation la bonne distance de runout dans un contexte géologique donné.
