Pdf Shallow Magma Mingling Driven Strombolian Eruptions At Mt Yasur Here, the strombolian activity at mt. yasur is analyzed. a rheological investigation indicates that the basaltic andesitic eruptive products contain an apparently homogeneous glass phase and yet, exhibit evidence of a distinct range of glass transition temperatures with multiple peaks occurring in individual samples. Pdf | mt. yasur volcano (vanuatu) has been increasingly recognized for its high frequency strombolian eruptions. strombolian activity is often regarded | find, read and cite all the research.

Science, 2007 strombolian type eruptive activity, common at many volcanoes, consists of regular explosions driven by the bursting of gas slugs that rise faster than surrounding magma. explosion quakes associated with this activity are usually localized at shallow depth; however, where and how slugs actually form remain poorly constrained. we used spectroscopic measurements performed during. We envisage a shallow conduit filled with crystal rich magma, forming a viscous and mobile plug that develops an effective yield strength from the surface to a depth of at least 2000 m, in which bubbles are trapped, grow, ascend towards the surface and burst in a typical strombolian eruption. The unstable nature of the measured glass transition behavior leads us to the inference that mingling is located in the shallow parts of the eruptive conduits, partly driven by rejuvenation of material slumped from the crater walls into an open conduit system. the dynamics of this process may expose the periodicity of the eruptions themselves. source #articles posted on 3 december 2012 with 0.
