Also provided are output parameters related to the plotting of strains/strain-fields using the Generic Mapping Tools software (http://www.soest.hawaii.edu/gmt/ ). The algorithm to calculate horizontal strains (or strain rates) through interpolation of GNSS velocities is based on the Shen et al (2015) method (doi: 10.1785/0120140247) This software package has received funding from the European Union's Horizon 2020 research and innovation programme EPOS under grant agreement N°676564

    Background This data is camera images and nozzle pressure gauge voltage traces from rapid decompression shots at the LMU shock tube facility. This data is discussed in the "Materials and Methods" section of the paper "Standing Shock Prevents Propagation of Sparks in Supersonic Explosive Flows". Electric sparks and explosive flows have long been associated with each other. Flowing dust particles originate charge through contact and separate based on inertia, resulting in strong electric fields supporting sparks. These sparks can cause explosions in dusty environments, especially those rich in carbon, such as coal mines and grain elevators. Recent observations of explosive events in nature and decompression experiments indicate that supersonic flows of explosions may alter the electrical discharge process. Shocks may suppress parts of the hierarchy of the discharge phenomena, such as leaders. In our decompression experiments, a shock tube ejects a flow of gas and particles into an expansion chamber. We imaged an illuminated plume from the decompression of a mixture of argon and <100 mg of diamond particles and observe sparks occurring below the sharp boundary of a condensation cloud. We also performed hydrodynamics simulations of the decompression event that provide insight into the conditions supporting the observed behavior. Simulation results agree closely with the experimentally observed Mach disk shock shape and height. This represents direct evidence that the sparks are sculpted by the outflow. The spatial and temporal scale of the sparks transmit an impression of the shock tube flow, a connection that could enable novel instrumentation to diagnose currently inaccessible supersonic granular phenomena. Accessing Data The prefixes of the filenames correspond to the shot dates and times listed in table S1 of the paper. The "_camera.zip" files contains tiff images of the camera frames. The ".ixc" file in each zip lists camera settings in plain text. The ".dat" file contains the voltage measurement of the nozzle pressure gauge. Row 1 is the header, row 2 is the time in seconds, and row 3 is the voltage of the pressure gauge in Volts. The peak pressure in the header can be used to relate the voltage to pressure.

    This dataset compiles SEM images, modelled isopach map and topographic profiles, and data of radiocarbon ages, parameters of Tephra2 and AshCalc codes of Holocene volcanic ashes of of Southern Puna and neighbouring areas (NW Argentina). SEM images detail differences among the Bolsón de Fiambalá, Cerro Blanco and Cueros de Purulla fallout ash deposits. Tephra2 code was used to simulate the ash fallout, and the AshCalc code to compare different methods for ash volume estimates associated with the 4.2 ka cal BP eruption of the Cerro Blanco Volcanic Complex. Topographic profiles are used to explain the secondary thickening of fallout ash deposits. Material suplementario (Figuras S1-S4 y Tablas S1-S4 del artículo Fernandez-Turiel, J.-L.; Perez-Torrado, F.

    The models can be used for global-local modelling and simulation of destress blasting of rock mass near mine. The data combines three separate 3D solutions: the first was obtained for the small-scale problem – face(s) blasting process, and the second for the global scale problem – seismic wave propagation within very large volume of surrounding rock mass and the last one was obtained for a quasi-2D problem.

The European Commission is not responsible for any use that may be made of the information it contains. Deception Island volcano (Antarctica) is one of the most closely monitored and studied volcanoes on the region. In January 2005, a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. We performed this experiment from aboard the Spanish oceanographic vessel 'Hesperides', and from five land-based locations on Deception Island (the Spanish scientific Antarctic base 'Gabriel de Castilla' and four temporary camps). This experiment allowed us to record active seismic signals using a large network of seismic stations that were deployed both on land and on the seafloor. In addition, other geophysical data were acquired, including bathymetric high precision multi-beam data, and gravimetric and magnetic profiles. To date, the seismic and bathymetric data have been analysed but the magnetic and gravimetric data have not. We provide P-wave arrival-time picks and seismic tomography results in velocity and attenuation. In this manuscript, we describe the main characteristics of the experiment, the instruments, the data, and the repositories from which data and information can be obtained.

    The data acquisition contract was funded by the "Programa estatal de fomento de la investigación científica y técnica de excelencia-subprograma estatal de generación de conocimiento" of the Ministry of economy and competitiveness and took place in 2015. Seismic data was successfully collected in Alhama de Murcia (Spain). The total amount of seismic reflection data collected was 13.2 km in 6 profiles NW-SE oriented. Technical specifications of the profiles: Receiver number: 240, Receiver interval: 2 m, Source: accelerated weightdrop 250 kg, Source interval: 6 m, Sample rate: 1 ms, Record time: 4 s. Contact people: Martínez-Díaz, J.; jmdiaz@geo.ucm.es and Carbonell, R.; rcarbo@ictja.csic.es This work is part of the research project: “InterGeo”. One of the main objectives of this project is to understand the seismogenetic behavior of the Alhama de Murcia Fault (FAM) located in the Betic Cordillera (Spain). In this study several intersegment areas were defined. Some structural and paleoseismic studies and geophysical surveys have been carried out on these zones.

    Fair and sustainable production of raw materials is one of the main challenges faced by our society. Through its RawMaterials Programme, the European Institute of Technology (EIT) encourages research and innovation solutions for mineral exploration to make them safer, sustainable and cost-effective. The SIT4ME project, funded by EIT, addresses these objectives by undertaking seismic mineral exploration methods in crystalline tectonic settings, at a reduced cost. The SIT4Me project will analyse the efficiency of passive seismic methods (i.e. ambient noise interferometry) for subsurface imaging, by comparing active- and passive-source datasets in mining areas. The files in this dataset correspond to the controlled-source acquisition. The acquired data comprises 2D/3D and 3C components. The acquisition employed 647 seismic receivers, distributed in a 3D mesh around the target and along six 2D crooked lines sampling the study area. The source employed was a 32 t vibroseis truck, operating at c. 900 points in the pathways along the 2D profiles. Each vibration point was used three times, with frequency sweeps of 10-100 Hz.

    The SHAPEness Metadata Editor is a Java desktop application conceived to help users creating and updating RDF metadata descriptions. It provides a rich user interface which allows users to easy populate and validate metadata, structured as graphs, against a set of SHACL constraints. The SHAPEness Metadata Editor has been developed in the framework of the European Plate Observing System (EPOS) where an extension of DCAT-AP, called EPOS-DCAT-AP, was created. As it is a SHACL-driven Metadata Editor, it is suitable for all kinds of domains or use cases which structure their knowledge by means of SHACL constraints.
