1. Present tectonic motion across the Coast Ranges and San Andreas fault system in central California.

Author

Argus, Donald F. and Gordon, Richard G.

Subjects
*GEOLOGIC faults, *STRUCTURAL geology
Abstract

Examines the tectonic motion across the Coast Ranges and San Andreas fault system in central California. Use of the assumption of the rigidity of plate interiors, a velocity model of plates and sites based on very long baseline interferometry; Observed strike of the faults; Testing of the hypothesis that stable sliding occurs along the San Andreas fault and other northwest-strikign strike-slip faults.

5. Exploring An Ominous Bulge: Scientists study puzzling earth movements in California.

Subjects
GEODETIC observations, STRUCTURAL geology, PLATE tectonics, EARTHQUAKES
Abstract

The article reports on the surveys conducted by 300 scientists under a 1.4 million dollars program of the National Geodetic Survey, the U.S. Geological Survey, and local authorities to study the gradual elevation of a large region around Palmdale, California. It notes that 36 teams of specialists are fanning across Southern California with levels, gravity meters and other exotic scientific gear for three months of intensive measuring. It cites that Palmdale sits atop the San Andreas Fault, the great crack that marks the boundary between two of the earth's shifting tectonic plates. It states that scientists fear that the ominous rise of the region, nick-named the Palmdale Bulge, could be the first hint of a future major earthquake along that section of the fault.
