macroseismn.

Brit.

/ˈmakrə(ʊ)ˌsʌɪzm/, U.S.

/ˈmækroʊˌsaɪzəm/

Origin: Formed within English, by compounding; partly modelled on a French lexical item. Etymons: macro- comb. form, seism n.

Etymology: < macro- comb. form + seism n., partly after French macroséisme (F. de Montessus de Ballore 1907, in Beiträge zur Geophysik 4 331). Compare earlier microseism n.

Geology. Now rare.

An earthquake, as opposed to an imperceptible earth tremor (cf. microseism n.). Formerly also (in Milne's use): †a major earthquake that involved the ‘nucleus’ of the earth as well as its crust (obsolete).

1903 J. Milne in Geogr. Jrnl. 21 2 (heading) Macroseisms, or large earthquakes.

1903 Sci. Amer. Suppl. 2 May 22855 Prof. Milne pointed out the distinction which exists between macroseisms, or large earthquakes, and microseisms, or small earthquakes. The former he described as world-shaking disturbances.

1907 Jrnl. Geol. (Chicago) 15 401 Great confusion exists because of the different uses of the terms ‘macroseism’ and ‘microseism’, as well as of the adjectives derived from them. The usage here is that of both Milne and de Montessus, which makes ‘macroseism’ apply to the greater disturbance on the ground.

1924 Bull. Seismol. Soc. Amer. 14 29 Various useful compounds [of seism] have been suggested, such as..macroseism, de Montessus, 1907, for an ordinary sensible earthquake.

1972 Gloss. Geol. (Amer. Geol. Inst.) 424/1 Macroseism, a syn. of earthquake, as opposed to microseism.
