/ˈvɔlkəˌnɪz(ə)m/,

/ˈvɑlkəˌnɪz(ə)m/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: volcanic adj., -ism suffix.

Etymology: < volcan- (in volcanic adj.) + -ism suffix, originally after either French volcanisme (1783 or earlier; 1861 in sense 2) or German Volcanismus (1802 or earlier). Compare slightly later vulcanism n. and earlier volcanist n.

Geology.

1. = vulcanism n. 1. Now rare.

1959 Jrnl. Eng. & Germanic Philol. 58 493 In an age of nuclear physics the appreciation of Goethe's thought is necessarily different from that in the age of galvanism, neptunism, and volcanism.

2. Volcanic action or phenomena; the state, condition, or character of being volcanic; = vulcanism n. 2. Cf. volcanicity n.
