Morphology

eruptional = eruption (transparent) = erupt + ion + al

The adjective is formed straightforwardly from 'eruption' plus '-al', so the relation is easy to infer.

Etymology

Eruptional comes from erupt, which breaks into e- 'out' and rupt 'break' and is the same root as rupture 'a break'. Think of a volcano 'breaking out' of the ground, which is why eruptional describes a sudden, violent outburst.
