These data represent a series of analyses exploring the seismic behaviours of low-cohesion volcanic sediments – in this case the Neapolitan Yellow Tuff - under varying strain rates. The data include deformation logs from triaxial compression experiments, and the accompanying 12-channel acoustic emission recordings at 10 MHz. These are paired with X-Ray Computed Tomography images of one of the cores from both before and after deformation, to examine damage behaviour. These data include: Deformation logs captured from the triaxial press Acoustic emission event data Processed acoustic emission sonograms for selected events Matlab code for processing of sonograms Matlab code for statistical analysis of the acoustic emission data Before and after X-Ray Computed tomography data for a core which underwent 2% strain at a rate of 4x10-6 s-1. These data relate to Rowley et al - Deformation controlled Long-Period seismicity in low cohesion volcanic sediments https://doi.org/10.31223/osf.io/7rkzv

Rock samples gathered from Naples area (40°53'29.42"N, 14° 6'25.74"E) Samples prepared by coring and grinding. Before and after deformation the samples were scanned by X-Ray microscope to form the computed tomography datasets. The deformation experiments were run using a digital control system on a Sanchez triaxial deformation cell. The pressure and linear deformation transducer readings, pump volume and flow-rate data, and calculated derived values are logged automatically by the control software. Simultaneously with the deformation, an acoustic emission logging system records triggering P-wave events across the sample, and logs each event as a separate 10 MHz stream of recoded voltages, with a separate record from each of the 12 sensors arranged around the sample. The trigger threshold for recording an event is set above the ambient electrical noise in the system. Each event is then processed using the included MatLab scripts to generate spectrograms of the frequency composition.
