The Daily Volcano Quote: volcanic eruptions are very local phenomena 21 April 2009

Volcanic eruptions are very local phenomena. At any given epoch they are confined to a few localities of very small relative extent. They have no general distribution in the sense of a widely-extended and connected system. Each volcano is an independent machine — nay, each vent and monticule is for the time being engaged in its own peculiar business, cooking as it were its special dish, which in due time is to be separately served. We have instances of vents within hailing distance of each other pouring out totally different kinds of lava, neither sympathizing with the other in any discernible manner nor influencing the other in any appreciable degree.
