USArray

<p>USArray (Seismic and Magnetotelluric Observatory) was one of the three components of the <a href="/facts/Earthscope/owpj8yyH">Earthscope</a> project, the other two components being the <a href="/facts/Plate_Boundary_Observatory/yuVkA6yY">Plate Boundary Observatory</a> (PBO) and the <a href="/facts/San_Andreas_Fault_Observatory_at_Depth/CDXzfobr">San Andreas Fault Observatory at Depth</a> (SAFOD). The components were funded by the <a href="/facts/National_Science_Foundation/FlDT8TbW">National Science Foundation</a> and were constructed, operated, and maintained as a collaborative effort with <a href="/facts/UNAVCO/anNqAnr3">UNAVCO</a>, the <a href="/facts/Incorporated_Research_Institutions_for_Seismology/dbmmzcf1">Incorporated Research Institutions for Seismology</a> (IRIS), and <a href="/facts/Stanford_University/JEQeF9z2">Stanford University</a>, with contributions from several other national and international organizations. 
</p><p>A major goal of USArray was to collect detailed <a href="/facts/Seismic/Lony1LYX">seismic</a> images of the North American <a href="/facts/Lithosphere/1mqaxASd">lithosphere</a>.  The data collected from USArray was integrated with <a href="/facts/Geologic/WGvVRIYF">geologic</a> observations made on the Earth's surface to help determine the geologic history of North America, as well as to better understand that geologic processes that are at work today.
