  The statistical properties of infrequent particle displacements, greater than
a certain distance, is known as jump dynamics in the context of structural
glass formers. We generalize the concept of jump to the case of a spin glass,
by dividing the system in small boxes, and considering infrequent cooperative
spin flips in each box. Jumps defined this way share similarities with jumps in
structural glasses. We perform numerical simulations for the 3D
Edwards-Anderson model, and study how the properties of these jumps depend on
the waiting time after a quench. Similar to the results for structural glasses,
we find that while jump frequency depends strongly on time, jump duration and
jump length are roughly stationary. At odds with some results reported on
studies of structural glass formers, at long enough times, the rest time
between jumps varies as the inverse of jump frequency. We give a possible
explanation for this discrepancy. We also find that our results are
qualitatively reproduced by a fully-connected trap model.
