DESCRIPTION:Physical systems characterized by stick-slip dynamics often di
 splay avalanches. Regardless of the\ndiversity of their microscopic struct
 ure\, these systems are governed by power-law distributions for\navalanche
  size and duration. I will focus on the interevent times between avalanche
 s instead and\,\nusing results from experiments on granular systems and nu
 merical simulations of emulsions\, show that\,\nunlike their distributions
  for size and duration\, the interevent time distributions are able to dis
 tinguish\ndifferent mechanical states of the system\, characterized by dif
 ferent volume fractions or confining pressures.\nRemarkably\, for large pa
 cking ratios\, these interevent time distributions look similar to those f
 or earthquakes\nand are indirect evidence of large non-trivial space-time 
 correlations in the system.
