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
Phreatomagmatic processes – energetics of
explosions from magma-water interaction, craters, deposits, and diatremes.
Explosives being used to
study the formation of maar craters and underlying diatremes.
