Connections between eruption style and magmatic reservoir evolution: Insights from Augustine Volcano, Alaska, USA
Research Mentor(s)
Dr. Kristina Walowski
Description
Volcanic eruptions can be hazardous and explosive events that are directly influenced by the processes of magma mixing beneath the surface. Understanding the connection between magmatic reservoir evolution and eruption style is key to determining the potential for a hazardous eruption. Despite this, reservoir evolution for many of the world’s active volcanoes are poorly understood. Augustine Volcano (Alaska, USA) is an ideal workspace to address the link between reservoir dynamics and volcanic explosivity because it is active and has a history of a variety of eruptive personalities. The moderately explosive modern (2006 CE) eruption has been well studied, in contrast to the potentially more explosive, understudied Late Holocene (ca. 1200 CE) eruption. My work will better constrain magma reservoir evolution beneath Augustine by analyzing the geochemistry of minerals and glasses in Late Holocene pumice clasts and constrain the parameters that potentially made this past eruption more explosive and hazardous.
