Summary: Gravitational instabilities pose significant threats to populations and infrastructure. This study focuses on estimating the geometry and volume of unstable masses in a volcanic cliff using remote observations. The analysis of the Samperre cliff in Martinique suggests a potential link between destabilizations and a paleo-valley filled with pyroclastic materials. The estimated volume of future destabilizations could be between 3.5x10(6) and 8.3x10(6) m(3).

Summary: Understanding the relationship between different components involved in the recycling of subducted sediment at arc volcanic systems is important. This study examines trace element variability along the Lesser Antilles Island Arc and suggests that sediment inputs via fluid transfer to the mantle wedge are necessary to explain certain trace element characteristics. The study also reveals variations in sediment composition along the arc and emphasizes the importance of considering localized variations in sediment contribution.

Summary: In this article, the tsunami hazard in Martinique due to tsunamis generated by earthquakes associated with the Lesser Antilles subduction zone is estimated. The western coast of the island is relatively sheltered, while the eastern coast is prone to frequent floodings with meter-scale wave amplitudes. Comparisons with previous studies reveal a tsunami hazard similar to a local scenario of lower magnitude. This has implications for generalizing the local tsunami hazard assessment in Martinique and increasing tsunami preparedness efficiency.

Summary: In this study, the long-term topography of Barbuda Island was investigated through the dating of corals on marine terraces. The results suggest that the terraces correspond to the Last Interglacial period and estimate a paleo relative sea level of 7 meters above the current sea level. The asymmetry of Barbuda Island and the difference in shoreline elevation between Barbuda and Antigua imply regional tectonic processes.

Summary: Understanding human-nature relationships has become a crucial issue in environmental management, and PPGIS methods have been widely used to demonstrate these relationships spatially on maps. However, the spatial data generated by PPGIS methods often lack the insights provided by participants' discourses. In this study, a web-mapping survey was conducted in Martinique to investigate the relationship between inhabitants' perceptions of rich nature and its spatial representation. The results showed a strong correlation between rich nature perception and spatial representation, highlighting the value of combining mapping and participants' discourses in participatory mapping.

Summary: This study used stable potassium isotopes to track the crustal signatures in lavas from Martinique Island in the Lesser Antilles arc. The results show that the variations in K isotopes in these lavas are related to chemical parameters and radiogenic isotope ratios, indicating modification of mantle sources by input of subducted sediments. Most lavas have <1% to 5% of subducted sediments added to their mantle sources, with some samples showing divergence likely caused by the addition of K-bearing fluids from slab dehydration.

Summary: The study reveals that lavas produced at subduction zones represent both source heterogeneity and an array of crustal processes, while plutonic xenoliths provide a complementary record of the deeper roots of the magmatic plumbing system and true chemical diversity of arc crust. Iron isotopic record demonstrates that magmatic processes within the sub-arc crust have a greater impact than sub-arc mantle inputs, and a light iron source is not necessary for producing the light iron isotopic compositions in volcanic arc lavas.

Summary: Stable potassium isotopes are being used as tracers for terrestrial recycling and planetary processes. This study investigated K isotope fractionation during the differentiation and solidification of the Kilauea Iki lava lake in Hawaii, and found no analytically resolvable fractionation, indicating a lack of K-rich minerals in the crystallizing assemblage. The results suggest an average delta K-41 of -0.42 +/- 0.08 parts per thousand for the pristine mantle and of -0.42 +/- 0.07 parts per thousand for the BSE.

Summary: Late Miocene to Pleistocene volcanic activity in the Vardar zone in North Macedonia is associated with the tectonic evolution of the South Balkan extensional system and the northern part of the Aegean extensional regime. The study focused on three volcanic centers with sparse geochronological and geochemical data, revealing that the onset of scattered potassic to ultrapotassic volcanism in the region occurred around 8.0 million years ago. This research provides insights into the evolution of sedimentary basins and the metasomatism of the lithospheric mantle over time.

Summary: The study of a volcanic eruption in the Pannonian Basin during the Miocene period reveals the interaction between the geosphere and biosphere. The volcanic ash covered the Ipolytarnoc Fossil Site, but the presence of uncharred tree trunks, branches, and intact leaves, as well as rock paleomagnetic properties, indicates that this was a low-temperature pyroclastic event that preserved the coastal habitat and unique fossil tracks.

Summary: The Cretaceous marine sedimentary record reveals periods with high organic matter content corresponding to oceanic anoxic events. The Weissert Event, occurring during the Valanginian stage, is the first such event in the Cretaceous. This study examines the potential triggers for the associated environmental changes and concludes that continental weathering, rather than volcanic activity, was the dominant source of nutrients in sediments from the central Moroccan margin during this time.

Summary: We conducted a large-scale geochemical sourcing study on stone artifacts excavated from archaeological sites in Vanuatu, the Solomon Islands, and the Caroline Islands. Our findings provide clear evidence of multiple long-distance voyages, with exotic stone materials being transported up to 2500 kilometers from their source. These results highlight the high mobility in the Western Pacific during the last millennium CE and shed light on the contacts between Polynesian Outliers, neighboring societies in the Western Pacific, and Western Polynesia.

Summary: This study uses multiple dating techniques to determine the timing of a volcanic collapse event and gain insights into its impact on volcanic activity. The results suggest that a collapse can trigger new growth and increase volcanic activity, while the overall composition of the magma plumbing system may not show significant variations. The study also highlights the importance of the zircon double-dating method for dating young lavas and debris avalanche deposits.
