a r t i c l e i n f o This work reports on the application and experimental validation, for idealized geometries, of a multiple-fluid Navier–Stokes model of waves generated by rigid and deforming slides, with the purpose of improving predictive simulations of landslide tsunamis. In such simulations, the computational domain is divided into water, air, and slide regions, all treated as Newtonian...

(2006). Modern saltmarsh diatom distributions of the Outer Banks, North Carolina, and the development of a transfer function for high resolution reconstructions of sea level. Retrieved from Abstract We collected modern diatom samples from Currituck Barrier Island, which have different salinity regimes due to their varying distances from a major barrier island inlet. Multivariate analyses separa...

On 30 December 2002 the coast of the volcanic island of Stromboli, in the Tyrrhenian sea, Italy, was attacked by two tsunamis generated by landslides that took place on the north-west flank of the volcano. The landslides and the tsunamis represented the most impressive and threatening episodes of a strong effusive eruption, started on 28 December from a new vent which opened close to the north-...

Introduction. The Mjølnir submarine crater (40 km in diameter and located in the Barents Sea) is interpreted as formed by the impact of an 1.5 to 2 km in diameter asteroid [1,2] into a 200–400 m deep epicontinental paleo-Barents Sea [3]. The target area consisted of a sedimentary sequence of Devonian to Jurassic age, at least 6 km thick, overlying older, well lithified sedimentary strata. The s...

The La Veteada Formation, in the Sierra de Famatina (west of Argentina), is one few records Early Triassic age South America verified by isotopic and palynological assemblages. This unit composed sandstones, mudstones, shales, limestones, marls, with some levels gypsum, chert, tuff levels. In its stratotype, Formation rests on Late Permian red beds Talampaya covered Neogene breccias conglomerat...

This study utilizes instruments from the Curiosity rover payload to develop an integrated paleoenvironmental and compositional reconstruction for 65-m thick interval of stratigraphy comprising Hartmann's Valley Karasburg members Murray formation, Gale crater, Mars. The consists cross-stratified sandstone (Facies 1), planar-laminated 2), mudstone 3). Facies 1 is composed showing truncated sets c...

Sudden large-scale geophysical flows such as cliff collapses, rockfalls, or massive landslides are known to be tsunamigenic and constitute a significant hazard for coastal populations infrastructures. A key challenge is able predict priori the amplitude of tsunami wave that would engendered by given collapse. In this study, we introduce comprehensive model shallow water waves generated subaeria...

A high-resolution multibeam survey from a portion of the San Simeon Channel (offshore Morro Bay, California) captured zone recurring troughs and ridges adjacent to prominent submarine meander bends. Through an integrated study using surveying data, sediment core analysis, radiocarbon dating, stable isotope measurements, we hypothesize that turbidity current event frequency was higher during lat...
