S33C:
Seismically Surveying North America: Synthesis and Emerging Ideas as USArray Spans Alaska and the CCArray Initiative Builds Momentum I Posters

Submit an Abstract to this Session



Session ID#: 24626

Session Description:
A systematic broadband seismic survey of an entire continent is a former pipe dream from the seismology community that has recently made major steps toward reality. The EarthScope program’s USArray Transportable Array has successfully covered the contiguous 48 states of the US, and is just reaching its maximum extent in Alaska and northwestern Canada. This session welcomes studies striving to synthesize new insights into continental structure, wave propagation, and seismic sources illuminated by comprehensive coverage of the contiguous US, as well as studies with nascent results and hypotheses from Alaska and northwestern Canada. Coverage of North America remains incomplete and the growing CCArray initiative may offer an opportunity to connect the existing broadband data sets by systematically sampling the Canadian Cordillera. Studies with relevance to the potential science targets, design, and capabilities of the CCArray concept are encouraged.
