Published on: 28-Aug-2019

Event Type: Seminar
Event Date: 28 August 2019 - 11:00am to 12:00pm
Venue: ASE 3D Viz Laboratory Room (N2-B1c-16c)
Speaker: Professor Katharine Cashman

About the speaker:

I studied for a BA degree in Geology and Biology at Middlebury College, Vermont, USA (1976), for an MSci (1st class Hons) at Victoria University, Wellington (New Zealand) and for a PhD in Earth Sciences at Johns Hopkins University, Maryland, USA (1986). My PhD project concerned applying theories of crystal size distributions to volcanic systems, and was supervised by Professor Bruce Marsh. I was an Assistant Professor at Princeton University, New Jersey, USA (1986-1991), and then an Associate (1991-1997) and Full (1997-present) at the University of Oregon. I came to Bristol in 2011 on a three year Research Professorship funded by the AXA insurance company. In December 2013 I was offered an AXA Endowed Chair at Bristol.  I was  Head of the Department of Geological Sciences, University of Oregon (2007-10) and President of the Volcanology, Geochemistry and Petrology (VGP) section of the American Geophysical Union (AGU; 2002-2004). In 2003 I was made a Distinguished Professor of the College of Arts and Sciences (Oregon), in 2007 I was made a Philip H. Knight Distinguished Professor of Natural Science (Oregon). I received the AGU VGP Bowen Award in 2006, was elected a Fellow of the AGU in 2009 and of the American Academy of Arts and Sciences in 2012. I currently hold a Royal Society Wolfson Research Merit Award.

About the event:

Real-time tracking and predictive modelling of volcanic ash dispersion, transport and deposition (VATD) rely largely on simple assumptions of ash properties. Real volcanic ash particles, however, vary in size, shape and density; measurement of these properties provides important insight into eruptive processes, and can be used to improve forecasts of ash hazards and impacts.
