Fig. 7: Effect of deformation rate.

Comparison of three experiments performed at different compression velocities: red crosses \({\dot{\varepsilon }}_{M}=3.5\,{\times} 1{0}^{-6}\) s⁻¹; green-filled triangles \({\dot{\varepsilon }}_{M}=1.1\,\times 1{0}^{-5}\) s⁻¹; open black circles: \({\dot{\varepsilon }}_{M}=3.5\,\times 1{0}^{-5}\) s⁻¹. a The normalized correlation function of the deformation (3) as a function of the time increment δt. b Same data plotted as a function of the strain increment δε_M. c Probability density dN/dM of events of moment M. (strain increment \(\delta {\varepsilon }_{M}^{* }=1.5\,\times 1{0}^{-6}\), event threshold (see Supplementary Methods 3) γ_s = 0.1 γ₀).
