Map: U.S. illustrating proposed Earthscope instrumentation.
Caption: , EarthScope, will generate basic scientific understanding of the structure and evolution of the North American continent and the physical processes controlling earthquakes and volcanic eruptions.
The slide shows a uniform grid of 2000 sites that researchers will sample over the next decade using portable seismic stations. An observatory four kilometers deep will directly monitor processes in the active San Andreas fault zone, while a distributed observatory will gather data on plate movements from Alaska to Mexico. Combined with new satellite and GPS systems, the entire EarthScope array will provide a dynamic picture of the forces that continue to shape earth.
NSF Funded: yes
