[en] We have experimentally studied granular arches through electrical measurements. The packing is composed of 2d metallic pentagons and is submitted to small taps. Large electrical fluctuations are observed and they are distributed along power laws. The indicates the presence of long-time memory effects event the packing density remains constant around a value rho = 0.72 +/- 0.02. Large electrical fluctuations should be associated with the breaking/creation of granular arches.
