Structural framework of United States Atlantic outer continental shelf north of Cape Hatteras Structural framework of United States Atlantic outer continental shelf north of Cape Hatteras
To assess the area’s hydrocarbon potential, regional geologic and geophysical studies are being conducted by the U.S. Geological Survey to determine the structural framework of the United States Atlantic outer continental shelf (AOCS) north of Cape Hatteras. Preliminary interpretations of geophysical data suggest that the buried ridge under the eastern edge of the AOCS in the Baltimore...

Geodimeter measurements of slip and strain accumulation along the San Andreas fault Geodimeter measurements of slip and strain accumulation along the San Andreas fault
The U.S. Geological Survey conducts repeated geodimeter surveys of trilateration networks in central California in order to study the processes of slip and strain accumulation along the San Andreas fault. The precision of distance measurement is described by a standard deviation σ = (a2+ b2L2)12 where a = (a2+ b2L2)12 where a = 3mm, b = 2 · 10−7, and L is the line length. Within the...
