EarthScope is funded by the National Science Foundation (NSF).
EarthScope has been constructed and is being maintained as a collaborative effort with UNAVCO,
Inc., the Incorporated Research Institutions for Seismology (IRIS), and Stanford University, with
contributions from the U. S. Geological Survey (USGS), National Aeronautics and Space
Administration (NASA), and several other national and international organizations.
What is EarthScope?
A nationwide effort to …..
• Explore the structure and evolution of the North American continent
• Study processes that cause earthquakes and volcanic eruptions
• EarthScope has three main “observatories” …..
Drillhole across San Andreas Fault
875 GPS Instruments
175 Borehole Strainmeters
5 Long-Baseline Laser Strainmeters
400 Seismometers at 2,000 sites
100 Permanent Seismometers

Transportable Array (TA)
Observatories
• Includes 400 Transportable Array (TA) Seismometers
• Each station occupies a site for 1½ to 2 years
• 10 years to leap-frog across the country
