Research Interests - G.A. Valentine
Volcanic risk – using our understanding basic volcanic
processes to predict the consequences of eruptions on human infrastructure, and
of the spatial-temporal behavior of volcanic systems to constrain eruption
probabilities.
Basaltic volcanism – all aspects of continental basaltic volcanism
with a focus on physical processes both at the scale of individual eruptions
and volcanoes, and at the scale of entire volcanic fields.
Paricutin scoria cone,
Mexico
Volcano fluid dynamics and
modeling – multiphase transport
processes associated with explosive eruptions and resulting deposits, volcanic
conduit flow, and magma ascent and interaction with surrounding crust.
Pyroclastic deposits – detailed studies of pyroclastic deposits from
very small scoria cones to major ignimbrites associated with large calderas,
and what those deposits tell us about eruption processes.
Miocene pumice fallout
beds in southern Nevada
Volcaniclastic and surface
processes – evolution of
volcanic landforms and deposits due to sedimentary processes, and effects of
primary volcanic facies on those processes, particularly in arid environments.
