CAMSIZER Particle Size Data from Explosive Paroxysms of Mt. Etna (2011–2025)

Tonato, Andrea | Andronico, Daniele | Corsaro, Rosa Anna | Caruso, Simona | Pistone, Mattia | Cristaldi, Antonio

2026

Mt. Etna in Catania, Italy, is an active volcano that has served as a natural laboratory for many volcanologists worldwide. Its paroxysms are unique eruptive events caused by a complex magmatic system that, despite being one of the most studied volcanoes, there is still an open field to...

Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”

Mohammad Hadi Mehranpour

2021

Reservoir compaction, surface subsidence and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field’s Slochteren sandstone reservoir rock, at in-situ conditions, have shown that compaction involves both poro-elastic...

Microstructure and mechanical properties of massive and porous of lavas from S. Miguel Island (Azores, Portugal)

Pereira, Maria Luísa | Buono, Gianmarco | Pappalardo, Lucia

2026

The role of elongated pores and crystals of lavas influences their mechanical and physical behaviour, providing a first microstructural clue. In the context of a doctoral project, two samples – a trachyte and a basalt/andesite (s.l.) - representative of Fogo Volcano (S. Miguel Island, Azores,...

Top-view and cross-section photographs from analogue experiments of strain partitioning around a rigid indenter performed in the Tectonic modelling laboratory (TecLab) at Utrecht University

Nemanja Krstekanić | Ernst Willingshofer

2020

This dataset contains original top-view and cross-section photographs of 12 crustal-scale analogue models. Top-view photographs were taken in regular time intervals from the beginning until the end of each experiment (for details see below). Cross-section photographs were taken at the end of...

Integrated measurements of capillary pressure, electrical resistivity, and elastic wave velocities conducted during sample drainage and imbibition under simulated reservoir conditions.

Kummerow, Juliane | Spangenberg, Erik

2026

Understanding how fluids migrate through underground rock formations is essential for securely storing carbon dioxide ($CO_2$), managing groundwater resources, or cleaning up contaminated soils. A key parameter in this context is the capillary pressure, the pressure difference between two...

Data supplement to: Mapping and classifying large deformation from digital imagery: application to analogue models of lithosphere deformation

Taco Broerse | Nemanja Krstekanic | Ernst Willingshofer

2021

The dataset consists of the original top-view and cross-section digital photographs of the model presented in Broerse et al. (2020) (Mappingand classifying large deformation from digital imagery: application to analogue models of lithosphere deformation.). The top-view images have been taken at...

Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field

Luuk Bernd Hunfeld

2021

Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (~1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We...

Surface DEM’s data and cross-sections from analogue experiments of subduction initiation performed in the Tectonic Laboratory (TecLab) at Utrecht University

Antoine Auzemery | Ernst Willingshofer

2020

In order to show the spatial and temporal evolution of deformation and associated surface topography, we present our results in terms of surface scans and final cross sections. The latter are pictures recorded at the end of the experiment. They are obtained at two-third of their width....

Rosenau, Matthias

2026

This dataset provides rheometric data of the PDMS Korasilon G 20 OH used for analogue modelling at the Laboratory for Experimental Tectonics at GFZ Helmholtz Centre for Geosciences, Potsdam, Germany. The batch number is 1000039264, purchased in 2022 and opened in 2026. The material sample...

Frictional slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates

Jinfeng Liu | Luuk Bernd Hunfeld

2020

We report seven velocity stepping (VS) and one slide-hold-slide (SHS) friction experiments performed on simulated fault gouges prepared from bituminous coal, collected from the upper Silesian Basin of Poland. These experiments were performed at 25-45 MPa effective normal stress and 100 ℃,...
