Origin of geyserAfter Icelandic Geysir, name of a hot spring of southwest Iceland, from geysa, to gush, from Old Norse; see gheu- in Indo-European roots.
Water contained in porous rock seeps into an opening. Heated by magma below, it escapes under pressure to the earth's surface.
From the name of a particular Icelandic geyser which is mentioned as early as the 1760s in The Annual Register, as “Geyser, a wonderful spring in the valley of Haukadal”. From Geysir (“Gusher”), the Icelandic name of the hot spring in Iceland (see), from the verb geysa (“to gush”), from Old Norse geysa (“to gush”).
