IAVCEI symposium at the IUGG in Montreal, July 2019. This symposium focuses on understanding what is the present day state of active calderas, or large magmatic systems, around the world. Studies from mafic or silicic systems are welcome. We seek to answer fundamental questions such as where is the magma? how much magma is there?, what state (i.e. temperature, melt, crystal, volatile content) is it in? These questions may be answered by geophysical or geochemical studies on caldera unrest, or from studies aimed at imaging present day magma reservoirs. We seek submissions from the geophysicists, analytic and numerical modelers, together with petrologists and geochemists, to constrain and interpret geophysical observations. The goal is to determine the hazard a caldera system poses in its present state. A larger goal would be to create a catalogue of active systems around the world to quantify the global hazard such systems represent. Abstracts are now open for submission at http://iugg2019montreal.com/abstract-submission.html The abstract submission deadline is February 18th 2019.
