Central and Easter United States Network
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.
TA Yukon Region
The Incorporated Research Institutions for Seismology (IRIS) is deploying 268 seismograph stations in Alaska and Yukon as part of EarthScope’s Transportable Array. The project is sponsored by the National Science Foundation and has cooperation and support from the Alaska Earthquake Center, University of Alaska-Fairbanks Geophysical Institute, as well as the Yukon Geological Survey and Canadian Hazard Information Service.
Due to its ongoing success with the EarthScope USArray project, the Array Network Facility has been requested to act as a data center for data collection, quality control, and web-based state-of-health monitor for several other real-time seismic experiments. These are listed and linked below.
