Abstract The seismic potential of the Lesser Antilles subduction zone is poorly known and highly debated. Only two damaging earthquakes have been reported in historical period, 1839 1843, but their sources magnitude are still uncertain. Global Navigation Satellite Systems coral data contradict each other, no conclusion has reached on coupling ratio plate interface. Given threat posed by possible occurrence a large megathrust earthquake, it crucial to gain information prehistorical events. We...
ABSTRACT Deep-sea and subseafloor sedimentary environments host heterotrophic microbial communities that contribute to Earth’s carbon cycling. However, the potential metabolic functions of individual microorganisms their biogeographical distributions in hadal ocean sediments remain largely unexplored. In this study, we conducted single-cell genome sequencing on sediment samples collected from six sites (7,445–8,023 m water depth) along an approximately 500 km transect Japan Trench during...
The International Ocean Discovery Program (IODP) Expedition 386, Japan Trench Paleoseismology, represents the first utilization of giant piston coring (GPC) within scientific ocean research drilling. This allowed for a Mission Specific Platform (MSP) multi-site, multi-hole, shallow subsurface in an ultra-deep water subduction zone trench. primary objective expedition was to investigate concept submarine paleoseismology Trench, which involves studying long-term records deposits deep sea that...
Abstract Hadal trenches are unique geological and ecological systems located along subduction zones. Earthquake-triggered turbidites act as efficient transport pathways of organic carbon (OC), yet remineralization transformation OC in these not comprehensively understood. Here we measure concentrations stable- radiocarbon isotope signatures dissolved inorganic (DOC, DIC) the subsurface sediment interstitial water Japan Trench axis collected during IODP Expedition 386. We find accumulation...

Abstract A major challenge in subaqueous palaeoseismology is to understand the relationship between an earthquake/tsunami and a sedimentary event deposit recorded drillcores. Expedition 381 of International Ocean Discovery Program was dedicated understanding development Corinth Rift, Greece. Its drilled cores provide potentially important resource better depositional mechanisms deposits within changing open marine (semi‐)isolated environments. To achieve this, U‐channels spatula samples were...
Three main types of factors commonly control the nature clasts, arrangement distinctive lithologies, and general architecture turbidite systems: sedimentation rate carbonate production; climates glacio-eustatism; morphology tectonics. The coexistence adjacent systems is, however, scarcely documented, relative influence each factor needs better constrain. In Northern Lesser Antilles Segment (NLAS), siliciclastic sediment sources coexist within a 150 km lateral distance, with platforms lying...
Abstract. Large megathrust earthquakes that rupture the shallow part of interface can cause unusually large co-seismic displacements and tsunamis. The long duration seismic source high upper-plate compliance contribute to protracted long-period motions. resulting shear stress at sediment/water in, for example, Mw9.0 2011 Tohoku-Oki earthquake, could account surficial sediment remobilization identified on outer margin. Through physical tank experiments, we test this hypothesis by exploring...
