Quantifying arc migration and the role of forearc subduction erosion in the central Aleutians

BR Jicha, SM Kay - Journal of Volcanology and Geothermal Research, 2018 - Elsevier
The active Aleutian arc is currently classified as an accreting margin as most of the arc has a
well-developed frontal accretionary prism that formed in the Plio-Pleistocene. We focus on …

Post-caldera volcanism reveals shallow priming of an intra-ocean arc andesitic caldera: Hunga volcano, Tonga, SW Pacific
