Digital spatial data for the map "Earthquakes in and near the northeastern United States, 1638-1998" [New Window]
The data are those used to make a large-format, colored map ofearthquakes in the northeastern United States and adjacent partsof Canada and the Atlantic Ocean (Wheeler, 2000; Wheeler andothers, 2001; references in Data_Quality_Information, Lineage).The ma
Digital map showing faults, lineaments, and earthquake epicenters in the Pahute Mesa 30' x 60' quadrangle, Nevada, in Arc/Info ASCII generate and Arc/Info export formats [New Window]
This digital map compilation incorporates fault, air photolineament, and earthquake epicenter data from within the PahuteMesa 30' by 60' quadrangle, southern Nye County, Nevada (fig. 1).The compilation contributes to the U.S. Department of Energy's Yuc
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Damaging Earthquakes [New Window]
This cover consists of location and size information for historicaland recent earthquakes that caused Modified Mercalli Intensity(MMI) VI (6) or higher in the map area. There were 26 earthquakesthat caused that level of damage. The most reknown are thefou
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Instrumental earthquake locations [New Window]
This cover contains the catalog of earthquake locations, within theproject boundary, recorded by the Saint Louis University and MemphisState University seismic networks from July 1974 through December 1995.
Seismotectonic maps in the vicinity of the lower Wabash Valley,Illinois, Indiana, and Kentucky - Digital Spatial Database:Modified Mercalli Intensity contours for the earthquakes fromDecember 16, 1811 at 815 GMT through June 10, 1987 at 2348 GMT [New Window]
Isoseismals of historic Central U.S. earthquakes are containedin 26 separate coverages. Margaret Hopper provided these isoseismals after reexamining theintensity data and re-calculating the isoseismal contours. Shegenerated isoseismal contours for each e
Possible Costs Associated with Investigating and Mitigating SomeGeologic Hazards in Rural Parts of San Mateo County, California [New Window]
This publication addresses deep-seated landslide susceptibility,debris flow susceptibility, and other geologic hazards in ruralparts of western San Mateo County. The report also estimatespossible costs of investigating and mitigating the landslidehazards
Seismic Landslide Hazard for the City of Berkeley, California [New Window]
This map describes the possible hazard from earthquake-inducedlandslides for the city of Berkeley, CA. The hazard depicted bythis map was modeled for a scenario corresponding to an M=7.1earthquake on the Hayward, CA fault. This scenario magnitude isass
Seismic Landslide Hazard for the Cities of Oakland and Piedmont, California [New Window]
This map describes the possible hazard from earthquake-inducedlandslides for the cities of Oakland and Piedmont, CA. Thehazard depicted by this map was modeled for a scenariocorresponding to an M=7.1 earthquake on the Hayward, CA fault.This scenario mag
Map and map database of susceptibility to slope failure bysliding and earthflow in the Oakland area, California [New Window]
Map data that predict the varying likelihood of landsliding canhelp public agencies make informed decisions on land use andzoning. This map, prepared in a geographic information systemfrom a statistical model, estimates the relative likelihood oflocal sl
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
