Abstract Fragmentation is a common feature of rockfall that exerts strong control on the trajectories generated blocks, impact energies, and runout. In this paper, we present set four real-scale tests aimed at studying fragmentation rocky from global design field procedure to data analysis main results. A total 124 limestone, dacite, or granite blocks ranging between 0.2 5 m 3 were dropped different heights (8.5 23.6 m) onto slopes with shapes (single double bench) slope angles (42º 71º)....
The analysis of seismic signals obtained from near‐source triaxial accelerometer recordings two sets single‐block rockfall experiments is presented. tests were carried out under controlled conditions in quarries northeastern Spain; the first test (Foj limestone quarry, Barcelona), 30 blocks released with masses ranging between 475 and 11,480 kg. second (Ponderosa andesite Tarragona) consisted release 44 466 to 13,581 An three high‐speed video cameras deployed, so that trajectories,...
Abstract In normally consolidated, shallow (depth <~3 km) siliciclastic sequences, faults develop clay smears. Existing models include the dependence of permeability on fraction, but improved predictions fault should account for uncertainty and anisotropy. We introduce PREDICT, a methodology that computes probability distributions directional components (dip-normal, strike-parallel, dip-parallel) tensor from statistical samples set geological variables. These variables, which...
Abstract. On 24 September 2013, an Ml 3.6 earthquake struck in the Gulf of Valencia (Spain) near Mediterranean coast Castelló, roughly 1 week after gas injections conducted area to develop underground storage had been halted. The event, felt by nearby population, led a sequence build-up events which reached maximum 4.3 on 2 October.Here, we study role static stress transfer as earthquake-triggering mechanism during main phase sequence, expressed eight events. By means Coulomb failure...
The accuracy and robustness of numerical models geologic CO$_2$ sequestration are almost never quantified with respect to direct observations that provide a ground truth. Here, we conduct injection experiments in meter-scale, quasi-2D tanks porous media representing stratigraphic sections the subsurface, combine them simulations those experiments. We evaluate (1) value prior knowledge system, expressed terms ex-situ measurements tank sands' multiphase flow properties (local data), obtain an...
Abstract. On September 24th, 2013, a ML 3.6 earthquake struck in Valencia Gulf (Spain), near the Mediterranean coast of Castellon, roughly week after gas injections conducted area to develop an Underground Gas Storage had been halted. The event, felt by nearby population, led sequence build-up events which reached maximum 4.3 on October 2nd. Here, we study role static stress change as triggering mechanism during sequence, and provide quantitative assessment known faults final state. By means...
<p>Accurate assessment of fault-related CO<sub>2</sub> migration hazard is required to deploy geologic carbon storage at the gigaton scale. First, we present a novel methodology, PREDICT, model intrinsic permeability faults in siliciclastic sequences. PREDICT models realizations fault core consistent with stratigraphy, and computes probability distributions for directional components (dip-normal, strike-parallel dip-parallel) fault-scale tensor....
