dc.description.abstract |
It has been long stated that there are profound analogies between
fracture experiments and earthquakes; however, few works attempt a
complete characterization of the parallelisms between these so separate
phenomena. We study the Acoustic Emission events produced during the
compression of Vycor (SiO&sub&2&/sub&). 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. |
