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” …..

IRIS Washington, DC

Observatories

PASSCAL Socorro, NM

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