Publication_Date: 4/1/96 Title: One centimeter tephra hazard from major Cascade volcanos Geospatial_Data_Presentation_Format: map Series_Information Series_Name: OFR 96-178j Publication_Information Publication_Place: Vancouver, WA Publisher: U.S. Geological Survey Online_Linkage: http://vulcan.wr.usgs.gov/Hazards/ Larger_Work_Citation: OFR 96-178 Scale_Denominator: 5000000Description Abstract This data set shows the tephra fall hazard zone for Mount Rainier (Hoblitt and others, 1995). The lines encompass several polygons each labeled for identification in the hazard zone. Four registration marks lie outside the polygons. The coverage in in the universal transverse mercator projection. This data set was used to produce inset maps of tephra fall hazard in the volcano hazard assessment of Mount Rainier, Washington (Hoblitt and others, 1995).

Keywords: None.
Purpose This data set is designed for display or visual inspection only and should not be used for detailed analysis. The polygon boundaries do not mark a distinct change between hazard and no-hazard areas. The degree of hazard decreases with increase of distance outside the boundary.
Supplemental_Information Procedures_Used The file was imported from inhouse software at the Cascades Volcanic Observatory using the DXFINFO and DXFARC commands. The file was edited in ArcEdit to remove annotation and add labels and attributes. The projection was defined as Universal Transverse Mercator with zone 10, units in meters, and a spheroid of Clarke 1866. The final coverage was plotted for visual inspection by the authors. The data set was renamed to casteph1 for annual probability of tephra fall in the northern Cascades of Washington 1 centimeter of ash.
