Geophysical studies of the Crump Geyser known geothermal resource area, Oregon, in 1975 [New Window]
Gravity map and data used to infer details of the geologic structure of the area. Surveys were conducted during or prior to 1975.
Geological, geophysical, and mineral resource data relevant to sandstone-hosted copper deposits in central Kazakhstan [New Window]
Central Kazakhstan is host to one of the world's giant sandstone-hosted copper deposits, the Dzhezkazgan deposit, and several similar, smaller deposits (Gablina, 1981; Susura and others, 1986; Cox and others, 2003; Hitzman and others, 2005). As part of it
Illinois, Indiana, and Ohio magnetic and gravity maps and data [New Window]
Aeromagnetic surveys of Illinois, Indiana, and Ohio, merged to form seamless grids across the state. Gravity anomaly data are provided as well.
Hazard maps of the U.S. [New Window]
The coverages were created using the gridded data available fromthis ftp site. Most of the gridded data for the United States is ata spacing of 0.1 degrees latitude and longitude. The higherresolution data available for California, Nevada, and part ofAri
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Global Positioning System stations [New Window]
This cover contains the location of global positioning systemstations that are located within the project boundary. Several GPSnetworks with various monument spacings are being used to monitordeformation in parts or all of the Mississippi embayment. One n
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Gravity and aeromagnetic surveying and modeling lines [New Window]
Lines in this cover show where gravity oe aeromagnetic data have beenmodelled to constrain subsurface structure. Gravity andmagnetic signatures result from deep structure, such as might be athypocentral depths of earthquakes. We show only the lines for wh
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Magnetotelluric sounding points and modelling lines [New Window]
Magnetotelluric soundings give data that can help define the lelectricamagnetic properties of rocks, and with othergeophysical data help define thestructure of the shallow crust where earthquakes occur. The soundingpoints in this cover show where data was
