Etymology[edit]

From Hawaiian ʻaʻā.

Pronunciation[edit]

Noun[edit]

aa (uncountable)

  1. (volcanology) A form of lava flow associated with Hawaiian-type volcanoes, consisting of basaltic rock, usually dark-colored with a jagged and loose, clinkery surface. Compare pahoehoe. [First attested in the mid 19th century.]
    • 1859, R. C. Haskell, American journal of science and arts, series XXVIII
      We...saw ‘pahoihoi’ or solid lava forming, and also ‘aa’ or clinkers.
    • 1883, Clarence E. Dutton, Fourth Annual report of the United States Geological Survey:
      The second form of the lavas is called by the natives a-a, and its contrast with pahoehoe is about the greatest imaginable. It consists mainly of clinkers sometimes detached, sometimes partially agglutinated together with a bristling array of sharp, jagged, angular fragments.
    • 1944, Charles A. Cotton, Volcanoes as landscape forms:
      Cooling and solidification frequently takes a different course [...] in lava flows, producing the clinker-like ‘aa’ lava.
    • 1999, A. Ganeri: Violent Volcanoes:
      A'a is thick, sticky lava which forms jagged, chunky rock when it cools.
    • 2004, Richard Fortey, The Earth, Folio Society 2011, p. 44:
      I overheard a geologist say that a good pair of boots can be rasped to bits on a‘a in a couple of months.
