Avalanche shape collapses.
Left column: averaged raw avalanche shapes. Middle column: Estimation of 1/(σνz) over the mean scaled avalanche profiles. Right column: scaling relation given by Eq 6. (A), (B) and (C) L = 50 with Γ = 0.50, (D), (E) and (F) L = 300 with Γ = 0.50. (G), (H) and (I) L = 50 with Γ = 0.80, (J), (K) and (L) L = 300 with Γ = 0.80. Gray shadow represents the standard deviation and orange trace the fitted scaling parameter. Model parameters: rE = 0.14 and rE = 0.12 for L = 50 and L = 300, respectively, with rI = 0.60.
