UAS-based micro-scale surface texture for different generations of the coastal alluvial fan Guanillos, Atacama Desert

Janek Walk, Melanie Bartz, Georg Stauch, Helmut Brückner & Frank Lehmkuhl
This dataset contains two micro-scale surface roughness measures - the standard deviation of slope (StdSlo) and the Vector Ruggedness Measure (VRM) - of the coastal alluvial fan Guanillos (GUA) in northern Chile (21.97°S, 70.17°W). Both roughness measures are derived from 5 cm digital elevation models (DEM) constructed based on surveys using an unmanned aerial system (UAS). Surface texture is quantified for three spatial scales of ca. 1 m, 2 m, and 3 m. Restricted to...

Whole-rock geochemistry of rock units from the Pfitscher Joch area, Western Tauern Window

Gerhard Franz, Eleanor Berryman, Martin Kutzschbach, Anette Meixner, Simone Kasemann, Friedrich Lucassen, Anselm Loges & Dina Schultze
In the Western Tauern Window, Zillertal Alps (Austria/Italy), metasediments of a Mesozoic intra-montane basin ("Pfitsch-Mörchner basin"; Veselá and Lammerer, 2008) are exposed. The (me-ta)sediments were deposited on a Variscan basement, which comprises different types of meta-granitoids and their (Pre)-Variscan metamorphic country rocks. The chemical composition (major and trace elements) of these rocks is presented for 205 samples. In the metasediments (103 samples), we distinguish the following units (from base to top): metaconglomerate (14 samples) –...

Stratigraphic and Multi Scanner Core Logging (MSCL) data plus supplementary luminescence dating material obtained from the scientific drilling QDR-RE-IfG and its drill site in the Aare Valley, Bern CH

Michael Schwenk, Fritz Schlunegger, Natacha Gribenski, Patrick Schläfli, Dimitri Bandou, Guilhem Douillet & Julijana Krbanjevic
The Quaternary Drilling at the Rehhag under the supervision of members of the Institut für Geologie (QDR-RE-IfG) was interested in the unconsolidated sediment infill of a bedrock trough in the Northern Alpine Foreland (NAF). Such bedrock troughs, now hidden beneath their sediment infill and/or in lakes, occur in formerly and currently glaciated areas, and are linked to increased glacial erosion. The base of these bedrock troughs is located beneath today's base level, which puts them...

Seismic Velocity Model of Crust and Upper Mantle beneath the Central Andes

Yajian Gao & Frederik Tilmann
We present a new seismic tomography model for the crust and upper-mantle beneath the Central Andes based on multi-scale full seismic waveform inversion, proceeding from long periods (40–80 s) over several steps down to 12–60 s. The spatial resolution and trade- offs among inversion parameters are estimated through the multi-parameter point-spread functions. P and S wave velocity structures with a spatial resolution of 30–40 km for the upper mantle and 20 km for the crust...

Comparing a new paleomap of European loess landscapes to an atmospheric dust circulation model

, Frank Lehmkuhl, Erik J. Schaffernicht, Stephan Pötter, Philipp Schulte, Patrick Ludwig, Tobias Sprafke & Ulrich Hambach
Loess is an important archive of environmental change covering approximately 10% of the Earth’s terrestrial surface. Numerous studies have analyzed loess deposits and in particular loess-paleosol sequences. To analyze these sequences, it is important to know the spatial distribution of aeolian sediments, their location relative to potential source areas, and the geomorphology of the sink area. We investigated these aspects by compiling a new map of aeolian sediments in Europe using highly resolved geodata from...

Seismic anisotropy and mantle deformation in NW Iran inferred from splitting measurements of SK(K)S and direct S phases - supplementary dataset

Shiva Arvin, Farhad Sobouti, Keith Priestley, Abdolreza Ghods, Khalil Motaghi, Frederik Tilmann & Tuna Eken
We investigate the anisotropic nature of the mantle in a part of the Arabia-Eurasia collision zone where several of the constituent tectonic blocks of Iran come into contact. Our aim is to identify the dominant source of anisotropy in order to infer the pattern of mantle deformation as it responds to the forces of continental convergence. The broadband seismic data used in this study were recorded by 68 seismic stations in three temporary arrays in...

DEUS: Damage-Exposure-Update-Service

Nils Brinckmann, Juan Camilo Gomez-Zapata, Massimiliano Pittore & Matthias Rüster
The software component DEUS (Damage-Exposure-Update-Service) is a Python3 script to evaluate/ update the physical damage and the structural vulnerability of a given building stock classified in terms of hazard-dependent classes (i.e. exposure model). This is obtained by estimating the damage evolution of the building stock given their initial damage state; the location of the scenario-based IM; and the use of selected fragility functions that must be compatible with the predefined building classes and IM. It...
