Multielement geochemical dataset of surficial materials for the northern Great Basin [More info]
This report presents geochemical data generated during mineral and environmental assessments for the Bureau of Land Management in northern Nevada, northeastern California, southeastern Oregon, and southwestern Idaho, along with metadata and maps.
PDF Facing the great disaster: How the men and women of the U.S. Geological Survey responded to the 1906 "San Francisco Earthquake" [More info]
After the powerful earthquake of April 18, 1906, staff of the U.S. Geological Survey stationed in Sacramento and Berkeley brought help to the residents of devastated San Francisco, documented the effects of the quake, and investigated its causes.
Groundwater quality in the Madera and Chowchilla subbasins of the San Joaquin Valley, California [More info]
Uranium, arsenic, and nitrate were the inorganic constituents that were most frequently detected at high concentrations, mostly in shallower wells. High and moderate concentrations of arsenic were detected in deeper wells.
Marin tsunami (video) [More info]
Guidelines for correct tsunami response and community preparedness from local emergency managers, first-responders, and leading experts on tsunami hazards and warnings.
PDF Assessment of remaining recoverable oil in selected major oil fields of the San Joaquin Basin, California [More info]
The mean total volume of potential oil reserves that might be added in the nine fields using improved oil-recovery technologies was estimated to be about 6.5 billion barrels of oil.
Groundwater quality in the Southern Sierra Nevada, California [More info]
Recent study indicating inorganic constituents as the primary items of concern in this area. Chemical and mineralogical compositions of the aquifer rocks probably explain variation among localities here.
Groundwater Quality in the Kern County Subbasin, California [More info]
Arsenic was the trace element most frequently present at high concentrations here. High concentrations of arsenic result from the interaction of groundwater with naturally occurring minerals.
Groundwater Quality in the Southeast San Joaquin Valley, California [More info]
Arsenic and nitrate are the constituents found most commonly at high concentrations in the primary aquifers. Arsenic comes from natural sources and is affected by pH and dissolved oxygen.
Groundwater quality in the Central Sierra Nevada, California [More info]
Recent study indicates that inorganic trace elements and radioactive constituents are more likely to be subjects of concern in this less-developed area than anthropogenic organic compounds.
Groundwater quality in the Middle Sacramento Valley, California [More info]
Results of a survey of contaminants in untreated groundwater in this area. Arsenic and boron were the two trace elements detected most frequently at concentrations greater than the benchmarks.
PDF Sutter Buttes-the lone volcano in California's Great Valley [More info]
Explains history and structure of this unusual geologic feature.
