The rupture of the original topology of toroidally nested flux surfaces needed to produce the island requires the reconnection of magnetic field lines, which can only occur with finite resistivity.

== Island growth and saturation ==
The prediction of the non-linear saturated state of islands is the goal of [[Neoclassical transport|Neoclassical]] Tearing Mode (NTM) theory.
This theory has been developed to a considerable level of sophistication, although discrepancies with experimental observations remain.
