3D representation of the emerging magnetic discontinuities during an avalanche generated in the course of the D-IFM simulation for j = 1800. The total duration of this event is 112 steps. During the early stages, the avalanche generates 12 discontinuities a), evolves with 74 discontinuities b), peaks with 104 discontinuities c), and decays with 86 discontinuities d), 41 discontinuities e), and 11 discontinuities f).
