Ash generation of volcanic lapilli during rotary tumbling
Hornby, Adrian | Küppers, Ulrich | Maurer, Benedikt M. | Poetsch, Carina | Dingwell, Donald B.
2020
Data supporting the publication Hornby, AJ, Kueppers U, Maurer BM, Poetsch C and Dingwell DB (2020) "Experimental constraints on volcanic ash generation and clast morphometrics in pyroclastic density currents and granular flows". In this study, fine ash is generated from lapilli-sized...
Host Rock Variability Powers the Diversity of Steam-Driven Eruptions
Montanaro, Cristian | Cronin, Shane J. | Scheu , Bettina Scheu | Kennedy, Ben | Scott, Bradley J. | Dingwell, Donald B.
2020
Steam-driven eruptions are explosions that frequently occur in volcanic and geothermal areas. They are powered by the sudden release and expansion of steam and liquid water trapped under high pressure within the pore spaces of host rocks. We have experimentally studied how the strength of...
Jet spreading and Jet inclination induced through complex vent geometry
Schmid, Markus | Kueppers, Ulrich | Cigala, Valeria | Sesterhenn, Jörn | Dingwell, Donald
2020
This dataset provides data from 36 rapid decompression experiments performed in the Fragmentation Lab at Ludwig-Maximilians-Universität München (LMU, Munich, Germany) supporting the publication Schmid, M, Kueppers U, Cigala V, Sesterhenn J and Dingwell DB (202x) “Release characteristics of...
Laboratory model data from experiments on fragmenting analogue rock avalanches
Haug, Øystein Thorden | Rosenau, Matthias | Rudolf, Michael | Leever, Karen | Oncken, Onno
2021
This data set includes various laboratory model data derived from analogue rock avalanche experiments on the role of fragmentation on runout behavior. Detailed descriptions of the experiments and monitoring and analysis techniques can be found in Haug et al. (submitted) to which this data set...
Particle size distribution analyses of volcanic ash from Campi Flegrei (Italy) and Sakurajima (Japan) volcanoes
Del Bello, Elisabetta | Taddeucci, Jacopo | Scarlato, Piergiorgio | Giacalone, Emanuele
2017
This data publication includes particle size distribution data of natural volcanic ash samples used as starting material for laboratory experiments simulating the aggregation/disaggregation of colliding volcanic ash particles. Full details of the experimental method can be found in Del Bello...
Dataset of Physical and Transport Property Variations Within the Carbonate-Bearing Fault Zones of the Monte Maggio Fault (Central Italy)
Trippetta, Fabio | Carpenter, Brett M | Mollo, Silvio | Scuderi, Marco M. | Scarlato, Piergiorgio | Collettini, Cristiano
2017
Here we report the raw data of the physical properties of carbonate samples collected along the Monte Maggio normal Fault (MMF), a regional structure (length ~10 km and displacement ~500 m) located within the active system of the Apennines (Italy). In particular, we report results coming from...
Friction data of simulated fault gouges derived from the Groningen gas field
Hunfeld, Luuk | Niemeijer, André | Spiers, Christopher
2017
We investigated the frictional properties of simulated fault gouges derived from the main lithologies present in the seismogenic Groningen gas field (NE Netherlands), employing in-situ P-T conditions and varying pore fluid salinity. Direct shear experiments were performed on gouges prepared...
Digital image correlation data from analogue modelling experiments addressing extension of weakened crust
Osagiede, Edoseghe E. | Rosenau, Matthias | Rudolf, Michael | Rotevatn, Atle | Gawthorpe, Robert | Jackson, Christopher A.-L.
2021
This data set includes the results of digital image correlation analysis applied to analogue modelling experiments (Table 1) on the effect of weakness during distributed crustal extension performed at the Helmholtz Laboratory for Tectonic Modelling (HelTec) of the GFZ German Research Centre for...
Supplementary material for analogue experiments on the impact of the lithosphere on dynamic topography
Sembroni, Andrea | Kiraly, Agnes | Faccenna, Claudio | Funiciello, Francesca | Becker, Thorsten W. | Globig, Jan | Fernandez, Manuel
2017
We present videos and figures from 22 scaled analogue models used to investigate the interactions between a density anomaly rising in the mantle and the lithosphere in a Newtonian system. The experimental setup consists of a two layers viscous lithosphere-upper mantle system obtained by using...
Stress strain data of experimentally deformed Carrara marble in the semi-brittle field
Rybacki, Erik | Niu, Lu | Evans, Brian
2021
The data set contains stress-strain data of Carrara marble experimentally deformed in triaxial compression at temperatures of 20 – 800°C, confining pressures of 30 – 300 MPa, and strain rates between 10-3 and 10-6 s-1. This range covers conditions, at witch marble deforms in the semi-brittle...
