EarthScope - EarthScope

Program Description: EarthScope is a vast project for deep geoscientific exploration of the entire North American continent, as well as our entire Earth, to better understand the materials it is made of, how it was assembled, and how it works — including its recurring earthquakes and active volcanoes. EarthScope scientists use state-of-the-art instruments and methods to collect data from seismic waves, crustal movements, Earth's magnetic field, rock and soil samples, and images obtain from aircraft and satellites. Our scientists analyze these diverse sets of data in combination with innovative laboratory experiments and theoretical modeling. The research produces transformative knowledge that helps us better explain geological phenomena, protect ourselves against natural hazards, and locate necessary resources. The expertise, enthusiasm, and findings of the EarthScope community constitute an increasingly rich resource for enhancing Earth science education in formal (K-12, college, university) and informal (parks, museums, media) settings. The EarthScope National Office education and outreach program facilitates dissemination of EarthScope science to educators and to the public with a focus on free-choice or informal learning environments.

Organization Description: Facilities are primarily operated through member universities and in cooperation with the U.S. Geological Survey. Membership comprises virtually all US universities with research programs in seismology, and includes a growing number of Foreign Affiliates. The UNAVCO consortium consists of more than 100 US academic Members and over 75 Associate Members (domestic and international). IRIS maintains data from regional networks, USArray network, and the EarthScope Magnetotelluric Array. In addition, the Northern California Earthquake Data Center (NCEDC) maintains a separate multi-terabyte online copy of these seismic data. The PBO web page provides access to geodetic data from multiple instrument networks. The 1100-station GPS network is the largest component, and raw and processed data are available from PBO and the UNAVCO Data Archive Interface. A subset of the GPS stations are streamed in real time.

Data Description: The USArray component of EarthScope is a continental-scale seismic observatory designed to provide a foundation for integrated studies of continental lithosphere and deep Earth structure. USArray consists of of a portable array (the Transportable Array) of 400 seismometers that have been 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. The Magnetotelluric Transportable (MT) Array comprises shorter-period investigations at hundreds of sites in the continental USA. Data from these sites are collected on a regular schedule through recovery of data storage modules.
