S33A:
Emerging Science from the EarthScope Transportable Array in Alaska and Canada I


Submit an Abstract to this Session


Session ID#: 58740

Session Description:
The USArray Transportable Array roll-out in Alaska and Canada was completed in the fall of 2017. It consists of 194 telemetered broadband seismic and infrasound stations designed for an approximately two-year deployment as an EarthScope-supported facility. This unprecedented systematic broadband coverage of the entirety of continental Alaska and far northwestern Canada provides the seismological community with a dataset intended to help illuminate long-standing questions and aid in new discoveries. The diverse tectonic environment of Alaska and northwest Canada provides a world-class setting for investigating seismicity, plate boundaries, distributed intraplate deformation, shallow subduction, active volcanism, infrasound phenomena, and myriad other earth processes. This session welcomes studies using all or part of this new community asset to investigate structures ranging from the crust to core, active tectonics, local, regional and teleseismic earthquakes or other elastic wave sources, and seismic wave propagation.
