Oregon's volcanoes: What have we learned from global advances in volcanology over the past decade?

Visiting Scholar Presentation

Katharine Cashman

University of Bristol

For the past century, the paradigm of the magma chamber -­‐ a single, melt-­‐dominated magma body -­‐ has informed models of magma evolution and underpinned studies of volcanic processes. Over the past decade, however, our views of subvolcanic systems have changed dramatically, and with them ideas about triggers for volcanic eruptions. In this talk I will review both past and present understandings of what lies beneath active volcanoes, with an emphasis on how these changing views are altering our perspectives on how volcanoes work, as well as their environmental and human impacts.

This program will be followed by an overview from Hannah Buckland, also from the University of Bristol, on current research of the fine ash deposit produced by the eruption of Mt. Mazama.
