Ultrasonic and mechanical data from laboratory shear failure experiments in fluid saturated Westerly granite (NERC Grant NE/S000852/1)

Data recorded during triaxial rock deformation experiments of Westerly granite in the presence of pressurised pore fluids (water). Data consists of mechanical data (load, displacement, confining pressure) and pore pressure data (up- and downstream pore pressure, upstream intensifier volume, four pore pressure transducers mounted on sample) for two experiments, recorded at low and high acquisition frequencies. Also contains .h5 files with all ultrasonic waveforms (active surveys and acoustic emissions). Dataset complementary to dataset ID165485 . Contains all data necessary to evaluate the results presented in the paper entitled: 'Rupture and afterslip controlled by spontaneous local fluid flow in crustal rock' by Aben and Brantut, submitted to Geophysical Research Letters, and available at arXiv (arXiv:).

Statement: Data generated using a triaxial pressure apparatus located at the UCL Rock and Ice physics laboratory, London. Triaxial apparatus was equipped with LVDTs, pressure transducers, an axial load cell, and miniature pore pressure transducers. These were all connected to a 'slow' acquisition system (1Hz) and a fast acquisition system (1kHz). In addition, an ultrasonic acquisition system was used for measuring of ultrasonic wavespeeds and recording of acoustic emissions during deformation, with continuous recording of the signal. For further information, see paper entitled: 'Rupture and afterslip controlled by spontaneous local fluid flow in crustal rock' by Aben and Brantut, submitted to Geophysical Research Letters.
