Fig. 3: Temporal statistical analyses of AE events.
From: Dislocation avalanches are like earthquakes on the micron scale
a The rate of aftershocks ras after a main shock with an energy given by the colour for d = 32 μm pillars (Omori law). b Curves of panel a) divided with the square root of the main shock energy Ems (aftershock productivity law). c Rate of foreshocks rfs before a main shock of energy given by the colours for d = 32 μm pillars (inverse Omori law). d PDF P(tw) of waiting times tw between subsequent AE events for pillars of various sizes. e P(tw) for d = 8 μm pillars and different platen speeds vp. f P(tw) re-scaled with the platen velocity vp. Note that the minimum tw of 20 μs, i.e., the minimum time between two subsequent AE events, is defined as one of the AE event individualization parameters (see Methods).
