Quaternary stratigraphic records provide evidence at both regional and global scales for climate and sea-level changes, as well as faunal and floral turnover and landscape evolution. These depositional archives that allow studying the geological evolution of the Earth include terrestrial and marine sequences. Marine successions mainly record globa...

This study uses the 3D crustal velocity model and the relocated earthquake hypocenters, including the 2018–2021 earthquake sequences, to re-assess the seismogenic structures at the northern Longitudinal Valley. Earthquake focal mechanisms and relocated hypocenters from earthquake clusters suggest a gentle west-dipping fault existing under the Longi...

The oases in the arid the Nefzaoua region in central-western Tunisia are associated with spring mounds. Spring mounds result from an exceptional succession of geomorphological, hydrogeological and climatic conditions and processes that follow each other in a specific order. They look like small volcanoes that range from 200 m to more than 2000 m in...

Volcanoes are widely distributed on the surface of the Earth and on other planets. Volcanic activities play a key role in the long-term evolution of the planetary atmosphere and geomorphology. Iron oxides on volcanoes often exist as the products of rapid magmatic oxidation driven by earlier lithogenesis or the weathering of primary iron-bearing min...

Rock glaciers are active sediment transport systems of high mountain periglacial environments. Driven by the internal deformation of their frozen core, they can convey substantial amounts of debris from their nourishing zone towards their front. Depending on the topographic conditions at the front slope, the released sediment is either overridden a...

Structural hydrologic connections, formed by the coaction of tectonic and climatic processes, facilitate the transfer of matter across Earth's surface. Large‐scale analysis of hillslope connectivity controls is lacking, thus limiting our understanding of the drivers of extremes, like floods and landslides, and benefits, like wetlands. Here, we mode...
