    "abstract": "We present results from a physical experiment which demonstrates that a\nsheared granular medium behaves in a manner analogous to earthquake activity.\nThe device consists of an annular plate rotating over a granular medium in a\nstick-slip fashion. Previous observations by us include a bounded critical\nstate with a power law distribution of event energy consistent with the\nGutenberg-Richter law, here we also reveal stair-case seismicity, clustering,\nforeshocks, aftershocks and seismic quiescence. Subcritical and supercritical\nregimes have also been observed by us depending on the system configuration. We\ninvestigate the predictability of large events. Using the quiescence between\n`shock\u0027 events as an alarm condition, it is found that large events are\nrespectively unpredictable, marginally predictable and highly predictable in\nthe subcritical, critical and supercritical states.",
