EarthScope is an Earth science program to explore the structure and evolution of the North American continent and to understand the processes controlling earthquakes and volcanoes. Site materials include an overview of the program, quarterly reports, an image gallery, and document archives. There are also descriptions of specific EarthScope initiatives: the San Andreas Fault Observatory at Depth (SAFOD), Plate Boundary Observatory, and USArray Seismic Observatory; and the instruments used in gathering data for these programs. The Data Access page provides datasets and tools for analyzing seismic, GPS, and strainmeter data, as well as materials (cutting and mud sample reports, core logs, lithological reports) from SAFOD. The Education and Outreach page provides information on upcoming workshops and professional development opportunities, and educational products and tools that use EarthScope data.

EarthScope applies modern observational, analytical, and telecommunications technologies to investigate the structure and evolution of the North American continent and the physical processes controlling earthquakes and volcanic eruptions. Imaging the crust and mantle at an unprecedented scale, EarthScope integrates new observations from cutting-edge land and space based technologies to measure deformation in real-time at continental scales. These observations, integrated with geologic data, yield a comprehensive time-integrated picture of continental evolution and link surface features with their structures at depth. The site houses a number of original data sources (such as real-time seismic data and maps), a gateway to current seismic news and events, and Earth sciences related community event calendars.
