We study the acoustic emission events produced during the compression of Vycor (SiO2). The Gutenberg-Richter law, the modified Omori's law, and the law of aftershock productivity hold for a minimum of 5 decades, are independent of the compression rate, and keep stationary for all the duration of the experiments. The waiting-time distribution fulfills a unified scaling law with a power-law exponent close to 2.45 for long times, which is explained in terms of the temporal variations of the activity rate.5 p.application/pdfeng(c) American Physical Society, 2013TerratrèmolsMaterials porososEarthquakesPorous materialsinfo:eu-repo/semantics/article6233902019-05-20info:eu-repo/semantics/openAccess
