Such past events at Newberry have included both quiet lava flows and explosive discharges of pumice and ash. The volcano is presently quiet, however, future eruptions could have impacts on the campgrounds, resorts, and lakes within the volcano's caldera as well as the settlements in the Paulina Creek valley west of the mountain. Scientists at the USGS Cascade Volcano Observatory created a GIS data layer, nbhaz, to depict zones subject to the effects of an explosive pyroclastic eruption (tephra fallout, pyroclastic flows, and ballistics). Additionaly, the same GIS data set includes: 1) Lava flow hazard zones, both within and out of the caldera. 2) A hazard zone for volcanic gasses. 3) A hazard zone for lahars/floods in Paulina Creek. Finally, a separate GIS data layer, nbwells, depicts drill holes on the flanks of Newberry Volcano that were used to estimate the probability of coverage by future lava flows. Purpose: These volcanic hazard zones are intended for use by public and private agencies to view, overlay with other Geographic Information System (GIS) data sets, and make maps of hazards from potential future eruptions of volcanoes in the Newberry Crater region. It is critical to understand the nature of the boundaries of the volcanic hazard zones. Although arcs serve as boundaries of hazard zones, the degree of hazard does not change abruptly at these boundaries. Rather, a volcanic hazard decreases gradually with increased distance from the volcano and above the valley floor. These volcanic hazards also span a range of size and recurrence. The hazard zones delineated in this data set portray events believed most likely from future activity in the Newberry Crater area. Areas outside the hazard zones, especially those having low relief, should not be regarded as hazard-free. Too many uncertainties exist in source, size, and mobility of future events to locate boundaries of zero-hazard zones with confidence.

The vectors in this data set were compiled and checked for accuracy at a scale of 1:100,000 and thereby should only be used at 1:100,000 or smaller scales. The data set is inappropriate for use at scales larger than 1:100,000. Doing so will produce inaccurate and unreliable results.

Logical_Consistency_Report: Polygon and chain-node topology present. Hazard zonation polygons are logically consistent throughout coverage. Completeness_Report: This data set includes hazard zones that may be affected by lahars, pyroclastic flows, lava flows, and volcanic gases during future activity of Newberry Volcano and other volcanic vents in the area. Additionally, it shows drill holes made on the north and south flanks of Newberry Volcano that were used to estimate coverage of future lava flows. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Original linework and points were compiled on mylar greenlines of U.S. Geological Survey topographic quadrangles created according to National Map Accuracy Standards. Digitized linework was plotted, registered to original linework, and inspected visually for discrepency of greater than a linewidth (approximately 0.007 inches). For computer modelling, Digital Elevation Models having cell sizes of about 62 ground meters or about 2 millimeters on the map at 1:100,000 scale were derived from Digital Line Graph contour layers that were created according to National Map Accuracy Standards. All linework and points were plotted with DLG contour layers to check for positional accuracy as are reasonable according to geologic and hydrologic principles. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: 1:100,000 scale Digital Line Graph (DLG) contours have contour intervals of either 50 or 40 meters as well as Digital Elevation Models have vertical accuracies according to the National Map Accuracy Standards. All linework and points were plotted with DLG contour layers to check for positional accuracy as are reasonable according to geologic and hydrologic principles. Lineage: Process_Step: Process_Description: Linework and points were captured by hand digitizing. Digitizing procedures: Arcs and points were digitized in tablet inches from lines inked on 1:24,000 or 1:100,000 scale topographic mylar greenlines. Each quadrangle was registered to the digitizer and re-registered to ensure that tics could be relocated with an RMS equal to or less than 0.004. Lines were digitized using a NODESNAP CLOSEST .05 and a weed tolerance of 0. A second coverage was CREATEd from the first. In INFO, the tics were changed from inch coordinates to decimal degree coordinates and saved. The decimal degree coordinate coverage was converted to a UTM projection using: INPUT PROJECTION GEOGRAPHIC UNITS DD PARAMETERS OUTPUT PROJECTION UTM UNITS METERS ZONE 10 PARAMETERS END Each coverage in inches was TRANSFORMed to the empty UTM coverage ensuring the transformation RMS was equal or less than 0.004 inches. The individual coverages were edgematched and merged into a single coverage. Coverages were checked for digitizing accuracy both before and after merging by plotting linework at 1:24,000 or 1:100,000 scale as appropriate and overlain on original linework.

The attribute can have values from 0 - 99. Each value represents the arcs that delineate SPECIFIC hazard areas in and around Newberry Crater. 0 Shows three (proximal and distal) hazard zones around Newberry. The zone with the outermost boundary is a region that would be subject to lava flows from eruptions on the Newberry volcano flank and from other vents in the greater area. The inner and smaller zone is subject to explosive pyroclastic eruptions of small to moderate volume in or near the caldera. Hazards here may include tephra falls, pyroclastic flows/surges, ballistic projectiles, and lava flows. The zone that extends to the west of the zones mentioned above shows the hazard area for lahars and floods on Paulina Creek in the event of volcanically induced surges of water from Pualina Lake. 1 Shows the southernmost extent of the lahar hazard zone on the Paulina Prarie 2 Shows the western boundary of the lahar hazard zone on the Paulina Prarie (boundary is dashed on map). It should be noted that attribute values both 1 and 2 show boundaries inferred by scientists. It is possible that very large lahars or floods could extend beyond these boundares. Areas immediately outside the boundary lines should not necessarily be considered free of hazard. 99 Shows the hazard zone surrounding the crater that would be subject to volcanic gasses during periods of volcanic unrest and increased gas emission. Additionally, the value represents the area of the upper west flank where Paulina Canyon might not contain peak flows during an exceptionally large flood event.
