About the ANF

The Array Network Facility component of the EarthScope USArray project is charged with ensuring all of the real–time data and metadata collected from the Transportable and Flexible Arrays (TA & FA) are transmitted, checked for quality, archived, and accessible online for researchers and the general public. We also ensure near real–time delivery of the data and metadata to the deep archive located at the IRIS Data Management Center (DMC) in Seattle, Washington.

About CEUSN

As the USArray Transportable Array entered the central and eastern United States, several Federal agencies (National Science Foundation, United States Geological Survey, United States Nuclear Regulatory Commission, and Department of Energy) recognized the unique opportunity to retain seismometers in this region beyond the original timeline of the deployed TA footprint. The selected long-term sub-array, known as the Central and Eastern United States Network (CEUSN), incorporates multiple criteria for site selection that were weighed by an inter-agency TA Station Selection (TASS) Working Group.

The mission of the CEUSN is to produce data that enables researchers and Federal agencies alike to better understand the basic geologic questions, background earthquake rates and distribution, seismic hazard potential, and associated societal risks of this region.
