Morphology
The meaning 'to suddenly become violent or chaotic' is directly derivable from combining 'erupt' (to burst forth suddenly), 'into' (expressing a change of state), and 'riot' (violent public disorder). This compositional pattern (e.g. 'erupt into X') is transparent and cross-linguistically common, so a B1 learner who knows the constituent words would likely infer the MWE meaning.
Etymology
Erupt into riot uses the image of a sudden burst: erupt, meaning to break out suddenly, and riot, meaning a crowd in chaos, like a calm protest that suddenly turns violent. So it means 'to suddenly become violent or chaotic'.
