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...

Detrital zircon (U-Th)/He thermochronometry data from the Leones Valley, Patagonian Andes

Sarah Falkowski, Todd Ehlers, Andrea Madella, Christoph Glotzbach, Viktoria Georgieva & Manfred Strecker
The data presented here were produced to study glacial and glacio-fluvial catchment erosion using 'tracer thermochronology' where detrital downstream samples can be used to infer the source elevation sectors of sediments when integrated with known surface bedrock ages from the catchment. For the first time, our study used the zircon (U-Th)/He (ZHe) method as tracer thermochronometer. The samples come from the Leones Valley at the northeastern flank of the Northern Patagonian Icefield, Chile (46.7° S)...

R-script notebook for Hierarchical Bayesian logistic regression for predicting landslides in north Patagonia, Chile

Oliver Korup
The file corresponds to a code written using the R software version 4.0.5 (R Core Team, 2021). We used a Bayesian robust regression to predict the posterior probability P(L) at which a given location yi in our study areas (north Patagonia, Chile) is classified as part of a landslide source, transport, or deposition area. We used the NUTS sampling scheme implemented in the STAN probabilistic programming language (Carpenter et al., 2017) to draw samples from...

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...

Sound emission from shock-tube experiments for volcanological investigations

Juan José Peña Fernández, Valeria Cigala, Ulrich Kueppers & Jörn Sesterhenn
Explosive volcanic eruptions generate sound mostly in the infrasound (<20 Hz), but also in the acoustic (>20 and < 20k Hz) frequency range. Sound from volcanoes is recorded and used to describe quantitatively properties of the eruptive column, e.g. mass flux, and therefore it has monitoring purposes. However, a physical understanding of the underlying processes, their efficiency, and – maybe most importantly – the acting parameters like gas overpressure, absolute gas/magma volume, fragmentation depth and...

Experimental data on scaled analogue experiments modelling GPS velocity field variations and kinematic partitioning in the Southern Andes (34°S to 42°S)

Jan Oliver Eisermann, Paul Leon Göllner & Ulrich Riller
The southern Andes are regarded as a typical subduction orogen formed by oblique plate convergence. Despite decades of studies, there is considerable uncertainty as to how deformation is kinematically partitioned in the upper plate. Using scaled analogue experiments modelling, we test the concept of dextral transpression for this orogen. We advocate that the GPS velocity field portrays interseismic deformation related to deformation of strong crust north, and weak crust south, of 37°S. Contrary to the...

Piercarlo Giacomel, Roberta Ruggieri, Marco Maria Scuderi, Elena Spagnuolo, Giulio Di Toro & Cristiano Collettini
Here we report the raw data of the friction experiments carried out on basalt-built simulated faults defined by rock-on-rock contacts and powdered gouge. The experiments were specifically designed to investigate the role of fault microstructure on the frictional properties of basalts and the fault slip stability, and were conducted with the rotary-shear apparatus (SHIVA) and the biaxial deformation apparatus (BRAVA), hosted at the National Institute of Geophysics and Volcanology (INGV) in Rome. Simulated faults were...

Python Script PyFAST Calibration v.1.0

Moritz O. Ziegler & Oliver Heidbach
The 3D geomechanical-numerical modelling of the in-situ stress state aims at a continuous description of the stress state in a subsurface volume. It requires observed stress information within the model volume that are used as a reference. Once the modelled stress state is in agreement with the observed reference stress data the model is assumed to provide the continuous stress state in its entire volume. The modelled stress state is fitted to the reference stress...
