Understanding the complexities of volcanoes that erupt just once

Authors


Abstract

Most of the world's volcanoes erupt only once and, often, only for a short time—a few days to a couple of weeks. Because of the brevity of the eruptions and possibly because of a presumed docility, singly erupting volcanoes, known as monogenetic volcanoes, are not nearly as well studied as their polygenetic fellows. Traditionally, researchers have assumed that monogenetic volcanic eruptions are simple in their dynamics. A new investigation by Barde-Cabusson et al., however, reveals that these volcanic eruptions can be highly complex, sometimes incorporating multiple phases and magma vents.
