Lunar Volcanic Eruptions: Range of Eruption Styles and Implications for Magma Ascent and Emplacement
Introduction: A wide variety of morphologic features representing a range of eruption styles has been documented on the Moon [e.g., 1-2]. We have characterized the nature of numerous steep-sided domes, small shields, cones, dark halo craters of internal origin, dark mantle deposits, linear rille-related deposits, and sinuous rille-related deposits on the Moon using Clementine multis-pectral, Ap...
متن کاملVolcanic eruption prediction: Magma chamber physics from gravity and deformation measurements
One of the greatest remaining problems in modern volcanology is the process by which volcanic eruptions are triggered. It is generally accepted that eruptions are preceded by magma intrusion [Sigurdsson and Sparks, 1978]. The degree of interaction between previously ponded magma in a chamber and newly intruded magma determines the nature and rate of eruption and also the chemistry of erupted la...

متن کاملMagma chamber behavior beneath a volcanic edifice
[1] The construction of a large volcanic edifice at Earth’s surface generates stresses in the upper crust whose magnitude is comparable to those of tectonic stresses and overpressures within a magma chamber. We study how this affects eruption behavior. Analytical calculations are carried out in two dimensions for a cylindrical reservoir with an internal overpressure in an elastic half-space wit...
متن کاملNano-volcanic Eruption of Silver
Silver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-volcanic eruption that is caused by interactions b...
