    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.

Ocean bottom seismometers were provided by the U.S National Oceanographic Instrument Pool. This publication reflects only the authors' views. 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.

    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.

    La construction du réseau sismologique et géodésique français Résif a été lancée en 2009 pour fédérer, moderniser et développer les moyens d’observation géophysique de la Terre interne. Cette infrastructure de recherche nationale est aujourd'hui intégrée à l'infrastructure européenne EPOS et participe activement à sa réalisation et à son évolution. Par ailleurs, certaines composantes de Résif-Epos font partie de structures fédératives à l’échelle mondiale.Résif-Epos se base à la fois sur des réseaux permanents et sur des parcs d’instruments mobiles pour effectuer des mesures sismologiques, géodésiques et gravimétriques continues. Les données recueillies révèlent la structure et les déformations de notre planète. Elles contribuent également à la gestion durable des ressources naturelles et à la maîtrise des risques naturels d’origine tellurique.En sismologie, Résif-Epos développe un réseau permanent et dense de près de 200 capteurs à large bande passante sur l’ensemble du territoire métropolitain. Pour le compléter, le réseau accélérométrique permanent dispose de capteurs plutôt dédiés à l’étude des mouvements forts et localisés dans les zones les plus sismiques en métropole et Outre-Mer.Ces réseaux permettent aux chercheurs de mieux connaître et d'imager l'intérieur de la Terre depuis la croûte jusqu’au noyau terrestre. Outils de base pour le suivi en temps réel de l’activité sismique, ils aident également à estimer l'aléa sismique, c’est-à-dire la probabilité qu'une secousse dépasse un certain seuil en un lieu et sur une durée donnés.Résif-Epos intègre également un réseau permanent de stations géodésiques. Capables de mesurer des vitesses de déplacement du sol de l’ordre de quelques dixièmes de millimètres par an, elles permettent de suivre les déformations de l’écorce terrestre et les processus à l’origine des reliefs et de la sismicité, notamment au niveau des failles.Résif-Epos dispose par ailleurs de gravimètres qui mesurent les variations infimes du champ de pesanteur et permettent d’étudier la répartition et la dynamique des masses à l’intérieur de la Terre.En complément de ces réseaux permanents, Résif-Epos coordonne différents parcs d’instruments mobiles qui permettent de densifier temporairement les mesures en France ou dans des zones à fort intérêt scientifique en Europe ou dans le Monde. Ouverts à toute la communauté scientifique académique, ils proposent des équipements variés, modernes et parfois exceptionnels, comme un gravimètre absolu basé sur la chute d’atomes froids. Un système d'information performant gère la dizaine de téraoctets de données collectée annuellement. Les données brutes sont analysées, validées puis centralisées afin d’être sauvegardées et mises à disposition en temps réel et gratuitement, suivant une politique de science ouverte. Chaque année, des dizaines de millions de requêtes sont effectuées sur les serveurs par des scientifiques du monde entier.L'Institut National des Sciences de l'Univers du CNRS coordonne le consortium Résif-Epos, composé de la majorité des universités et organismes français concernés par la recherche en Géosciences. Plus d'une centaine de chercheurs, ingénieurs et techniciens collaborent au quotidien pour faire de Résif-Epos un formidable outil scientifique au service de la communauté mondiale des sciences de la Terre.

    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 data acquisition contract was awarded to ENRESA and took place in November and December 2013. Seismic data was successfully collected in the Záncara river basin (Cuenca, Spain). The total amount of seismic reflection data collected was 9.7 km in 4 high-resolution seismic reflection profiles E-W oriented. Technical specifications of the profiles: Seismometer: 10 24-channel GEODE ultra-light seismic recordes, Receiver number: 240, Receiver interval: 2 m, Source: accelerated weightdrop 250 kg and 100 kg, Source interval: 6 m, Sample rate: 1 ms, Record time: 4 s. Contact person: Carbonell, R., rcarbo@ictja.csic.es A high-resolution 2-D seismic reflection survey was acquired to obtain a seismic image of the geological structure of the Záncara river basin (eastern Spain). The study area consists of lutites and gypsum from a Neogene sedimentary sequence. The project also targeted the geometry of the geological structure and the mechanical properties of the underground materials. In addition, this study allowed for an improvement of the geophysical acquisition technics and protocols that provided with a better resolution seismic imaging. Thus, reducing costs and improving the effectiveness of the seismic acquisition. Convenio Colaboración CSIC-ENRESA. Código CSIC: 20133830 Peer reviewed

    La construction du réseau sismologique et géodésique français Résif a été lancée en 2009 pour fédérer, moderniser et développer les moyens d’observation géophysique de la Terre interne. Cette infrastructure de recherche nationale est aujourd'hui intégrée à l'infrastructure européenne EPOS et participe activement à sa réalisation et à son évolution. Par ailleurs, certaines composantes de Résif-Epos font partie de structures fédératives à l’échelle mondiale.Résif-Epos se base à la fois sur des réseaux permanents et sur des parcs d’instruments mobiles pour effectuer des mesures sismologiques, géodésiques et gravimétriques continues. Les données recueillies révèlent la structure et les déformations de notre planète. Elles contribuent également à la gestion durable des ressources naturelles et à la maîtrise des risques naturels d’origine tellurique.En sismologie, Résif-Epos développe un réseau permanent et dense de près de 200 capteurs à large bande passante sur l’ensemble du territoire métropolitain. Pour le compléter, le réseau accélérométrique permanent dispose de capteurs plutôt dédiés à l’étude des mouvements forts et localisés dans les zones les plus sismiques en métropole et Outre-Mer.Ces réseaux permettent aux chercheurs de mieux connaître et d'imager l'intérieur de la Terre depuis la croûte jusqu’au noyau terrestre. Outils de base pour le suivi en temps réel de l’activité sismique, ils aident également à estimer l'aléa sismique, c’est-à-dire la probabilité qu'une secousse dépasse un certain seuil en un lieu et sur une durée donnés.Résif-Epos intègre également un réseau permanent de stations géodésiques. Capables de mesurer des vitesses de déplacement du sol de l’ordre de quelques dixièmes de millimètres par an, elles permettent de suivre les déformations de l’écorce terrestre et les processus à l’origine des reliefs et de la sismicité, notamment au niveau des failles.Résif-Epos dispose par ailleurs de gravimètres qui mesurent les variations infimes du champ de pesanteur et permettent d’étudier la répartition et la dynamique des masses à l’intérieur de la Terre.En complément de ces réseaux permanents, Résif-Epos coordonne différents parcs d’instruments mobiles qui permettent de densifier temporairement les mesures en France ou dans des zones à fort intérêt scientifique en Europe ou dans le Monde. Ouverts à toute la communauté scientifique académique, ils proposent des équipements variés, modernes et parfois exceptionnels, comme un gravimètre absolu basé sur la chute d’atomes froids. Un système d'information performant gère la dizaine de téraoctets de données collectée annuellement. Les données brutes sont analysées, validées puis centralisées afin d’être sauvegardées et mises à disposition en temps réel et gratuitement, suivant une politique de science ouverte. Chaque année, des dizaines de millions de requêtes sont effectuées sur les serveurs par des scientifiques du monde entier.L'Institut National des Sciences de l'Univers du CNRS coordonne le consortium Résif-Epos, composé de la majorité des universités et organismes français concernés par la recherche en Géosciences. Plus d'une centaine de chercheurs, ingénieurs et techniciens collaborent au quotidien pour faire de Résif-Epos un formidable outil scientifique au service de la communauté mondiale des sciences de la Terre.
