Abstract: Subduction zones are a major expression of tectonics and cause
of volcanism on Earth, with a linear extent of approximately 40,000 km
at the surface. Their study brings together a variety of disciplines
within the geosciences, including seismology, geodynamics, geochemistry,
and mineral physics. This cross-discipline study is particularly
important, and exciting, when understanding the subarc regions of
subduction zones, due to the complexity of processes involved in
seismogenesis and melt generation. In this talk, I will focus on a small
subset of the many seismic tools that are used to study subduction
zones, specifically earthquake relocation and velocity tomography. For
example, at the global scale, seismicity can be used to constrain the
geometries and consequently the geodynamics and mineralogies of
subduction zones, helping us understand the features common to all
subduction systems. At a local scale, I focus on Central America, where
tomographic studies can provide insight to temperature and fluid
distributions and their along-arc variations, linking the inputs to the
outputs of subduction zones.
