USARRAY

USArray is one of the three components of the Earthscope project, funded by the National Science Foundation and being constructed, operated, and maintained as a collaborative effort with UNAVCO Inc., the Incorporated Research Institutions for Seismology, and Stanford University, with contributions from several other national and international organizations. A major goal of USArray is to collect detailed seismic images of the North American lithosphere. The data collected from USArray will be integrated with geologic 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.

The instrumentation of USArray will consist of a portable array of 400 seismometers that will be deployed across the United States over a 10 year period. In addition a "flexible component" array will be available to be deployed in areas where a denser network of seismometers is required. A permanent array of seismometers that is currently maintained by the USGS will also be augmented.

The other two components of EarthScope are the Plate Boundary Observatory PBO and the San Andreas Fault Observatory at Depth SAFOD.
