摘要：

We present an analysis of results obtained from a mechanical apparatus consisting of an annular plate shearing over a granular bed. The size, energy dissipation, and duration of slips in the system exhibit power law distributions and a 1/f(2) power spectrum, in accordance with self-organized criticality. We draw similarities with earthquakes.
