Foreshocks and aftershocks of the great 1857 California earthquake Foreshocks and aftershocks of the great 1857 California earthquake
The San Andreas fault is the longest fault in California and one of the longest strike-slip faults anywhere in the world, yet we know little about many aspects of its behavior before, during, and after large earthquakes. We conducted a study to locate and to estimate magnitudes for the largest foreshocks and aftershocks of the 1857 M 7.9 Fort Tejon earthquake on the central and southern...

Digital data for the geologic framework of the Alaska Peninsula, southwest Alaska, and the Alaska Peninsula terrane Digital data for the geologic framework of the Alaska Peninsula, southwest Alaska, and the Alaska Peninsula terrane
These digital databases are the result of the compilation and reinterpretation of published and unpublished 1:250,000- and 1:63,360-scale mapping. The map area covers approximately 62,000 sq km (23,000 sq mi) in land area and encompasses much of 13 1:250,000-scale quadrangles on the Alaska Peninsula in southwestern Alaska. The compilation was done as part of the U.S. Geological Survey's...

Digital mining claim density map for federal lands in Nevada: 1996 Digital mining claim density map for federal lands in Nevada: 1996
This report describes a digital map generated by the U.S. Geological Survey (USGS) to provide digital spatial mining claim density information for federal lands in Nevada as of March 1997. Mining claim data is earth science information deemed to be relevant to the assessment of historic, current, and future ecological, economic, and social systems. There is no paper map included in this...

Principal facts for gravity stations and physical property measurements in the Lake Mead 30' by 60' quadrangle, Nevada and Arizona Principal facts for gravity stations and physical property measurements in the Lake Mead 30' by 60' quadrangle, Nevada and Arizona
The U.S. Geological Survey (USGS) collected 811 gravity stations on the Lake Mead 30' by 60' quadrangle from October, 1997 to September, 1999. These data were collected in support of geologic mapping of the Lake Mead quadrangle. In addition to these new data, gravity stations were compiled from a number of sources. These stations were reprocessed according to the reduction method...

Geologic datasets for weights-of-evidence analysis in northeast Washington: 2. Mineral databases Geologic datasets for weights-of-evidence analysis in northeast Washington: 2. Mineral databases
Digital mineral databases are necessary to carry out weights-of-evidence modeling of mineral resources for epithermal gold and carbonate-hosted lead-zinc deposits in northeast Washington. This report describes spreadsheet tables consisting of: 1) training sites for epithermal gold, 2) placer gold sites, 3) training sites for carbonate-hosted lead-zinc, and 4) small lead-zinc mines and...
