Description:

Abstract:

This dataset provides a detailed (1:10,000) digital map of fault and fold traces in Alaska, USA based on features identified in the freely available ArcticDEM 3.0. The fault traces represented in this dataset either revise the location and accuracy of known active faults or folds archived in the USGS Quaternary Fault and Fold Database, or represent the surface traces of active structures not previously recognized.

Purpose:

The purpose of this dataset is to update the USGS Quaternary Fault and Fold Database with mapping based on the highest-resolution digital topography available.

Data_Set_Credit:

Adrian Bender mapped fault and fold traces in ArcMap 10.8 over slope and hillshade renderings of the ArcticDEM 3.0 provided by ESRI and accessed through ArcGIS Online, Peter Haeussler supervised the mapping. Evan Thoms, Camille Collett, and Dennis Walworth reviewed the data release. ArcticDEM digital elevation models created by the Polar Geospatial Center under NSF-OPP awards 1043681, 1559691, and 1542736 enabled this mapping.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Attribute values were checked for consistency with mapped features and, where applicable, cross-referenced for accuracy and consistency with attributes in the U.S. Geological Survey Quaternary Fault and Fold Database.

Logical_Consistency_Report:

No formal logical accuracy tests were conducted, but visual inspection and review indicates that attribute values are consistent with the indicated scales of mapping relative to the base topography. All features are digitized in the strike direction according to the right-hand rule convention of Aki and Richards (1980); direction of digitization is consistent with SlipSense and Feature.

Completeness_Report:

This dataset contains linework that completely describe the surface traces of faults considered in the area of interest. Continuity breaks in the linework represent locations where visually identifiable surface fault features are not identifiable in slope or hillshade renderings of the ArcticDEM 3.0.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The locational accuracy of the mapping reflects the 1:10,000 scale at which the originators mapped all features. The real-world accuracy of the ArcticDEM 3.0 as of this data release is not yet defined, but the ESRI-generated renderings used for this mapping (available via ArcGIS online) have horizontal and vertical accuracies estimated at 4 meters (https://www.arcgis.com/home/item.html?id=db38a951a2b643478a942ab22cd78fc6).

Digital elevation model used to generate slope and hillshade renderings from which the originators interpreted and mapped fault and fold traces.

Process_Step:

Process_Description:

ESRI ArcMap (version 10.8.1) software was used to map the surface traces of faults and folds over the slope and hillshade renderings of the 2.0 meter/pixel ArcticDEM 3.0 where location accuracy and detail could be improved relative to the U.S. Geological Survey Quaternary Fault and Fold Database (QFFD), or where fault and/or fold traces were identified but no corresponding feature was previously archived in the QFFD.

Enumerated_Domain_Value: Strike-slip
Enumerated_Domain_Value_Definition:

Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. If the block opposite an observer looking across the fault moves to the right, the slip style is termed right-lateral; if the block moves to the left, the motion is termed left-lateral.

Enumerated_Domain_Value: Normal
Enumerated_Domain_Value_Definition:

Dip-slip faults are inclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed reverse. A thrust fault is a reverse fault with a dip of 45 degrees or less. Oblique-slip faults have significant components of different slip styles.
