This data release provides access to an aeromagnetic survey over a part of northeastern California, an area that includes the city of Alturas, California. The survey extends across the Devils Garden part of the Modoc Plateau (west of the Warner Range) and westward to over Medicine Lake volcano. The survey covers the Likely fault zone, an enigmatic northwest-striking set of structures...

This dataset accompanies geologic map publication " Geologic and geophysical maps of the onshore parts of the Santa Maria and Point Conception 30' x 60' quadrangles, California "; U.S. Geological Survey Scientific Investigations Map 3473. Data presented here include the digital geologic map database, paleontological sample locations and descriptions, and point data sets from magnetic and...

This data release contains data from flightlines collected during an aeromagnetic survey of the Burney region of northeastern California. These data were gridded and magnetization boundaries were calculated using the maximum horizontal gradient method on the gridded data.

This dataset contains gravity data collected in the HInkley area in the Mojave Desert of southern California.

Seismic hazard assessments depend on an accurate prediction of ground motion, which in turn depends on a base knowledge of three-dimensional variations in density, seismic velocity, and attenuation. The datasets here are components of a National Crustal Model that couples geologic characteristics and geophysical parameters using a physical theoretical foundation combined with measured...

The datasets consist of principal fact information of gravity data and density and magnetic properties of hand samples in the Chico and Willows 1:100,000-scale quadrangles, California.
