The Túnel de la Atlántida (Lanzarote, Canary Islands) is the world's largest submerged lava tube, formed by the La Corona eruption during the Last Glacial Maximum (LGM). This study reconstructs the Late Pleistocene-Holocene sea-level and paleoenvironmental changes preserved within the tunnel through an integrated sedimentological, petrographic, mineralogical (XRD, SEM-EDS), stable-isotope, and geochronological (U-Th, 14C) framework.

Bover-Arnal, Telm (Universitat de Barcelona)
Iberia and its oceanic margins provide evidence of a large rift system developed in three phases: i) late Permian-Middle Triassic, ii) Late Jurassic, and iii) Barremian-early Albian. These rifting events were coeval with the opening of the Alpine Tethys, the North-Atlantic, and the Bay of Biscay domains, respectively. [...]

Landform recognition and surface analysis are critical in geomorphological and morphotectonic studies. In particular, the detailed study of the surface expression of active faults is essential for their characterization as seismic sources in fault-based seismic hazard models. [...]
