Strainmeter Helps NASA Identify Continental Drift

TEGAM 1949-0001 ratio transformer TEGAM Geneva, OH 440-466-6100 www.tegam.com The EarthScope Project is an undertaking funded by the National Science Foundation in partnership with the United States Geological Survey and NASA to characterize the geology of North America, including continental drift caused by earthquake faults. Capturing the slow movement (which in some areas happens over centuries) can be done by measuring strain. Capturing strain (the deformation caused by stress) also can highlight areas that are moving faster along a fault relative to other areas.
