Description:
Abstract:
This data set provides a photogrammetry-based digital elevation model (DEM) that covers ~90% of the surface trace of the Eastern Denali Fault between the Alaska-Yukon international border and the village of Haines Junction, Yukon, Canada. The DEM has an average resolution of 4 m/pixel.
Purpose:
The eastern section of the Denali Fault did not rupture during the 2002 Denali Fault earthquake (Mw 7.9), however seismologic, geodetic, and geomorphic evidence along with a paleoseismic record of several past ground-rupturing earthquakes demonstrate the fault is active. Thick vegetation, along with complex glacial landforms, large braided rivers, and fault-parallel bedrock structure (e.g., bedding) obscure the Eastern Denali Fault’s surface expression. Plafker and Clague mapped the fault in Alaska and Yukon respectively, providing the basis for generalized digital maps of the structure. While the generalized fault trace maps provide basic information for seismic hazard models (i.e., approximate fault location, total length), detailed fault trace maps may reveal information about past rupture length and offset, complementing paleoseismic information and informing future field investigations. The 13 photogrammetry-based DEMs in this data set cover the ~90% of the active Eastern Denali Fault at a resolution of 3-5 m/pixel. The DEMs facilitate mapping of the co-located Eastern Denali Fault surface trace at a scale of 1:10,000. The DEMs complement other data sets and may inform future investigations by providing an openly accessible digital topography dataset and forms one of several datasets on which we base our mapped interpretation of the location, length, and continuity of the fault’s surface trace. The derivative digitized fault trace may provide geometric constraints useful for modeling earthquake scenarios and related seismic hazard.
Supplemental_Information:
We provide a supplemental text file (edf_airphoto_tbl.csv) that documents the file name, year of acquisition, and digital source for each legacy air photo used as source material for the photogrammetric DEM.

Data_Set_Credit:
We thank the NSF EarthScope program for the publicly available Denali Fault lidar dataset used in this map (available by searching www.opentopography.org). Thanks to Geomatics Yukon for providing digitized air photos over the fault in the Yukon. We acquired additional Yukon air photos and the 30 m Yukon DEM from the USGS Earth Explorer online portal (earthexplorer.usgs.gov). The IfSAR data used in this map was acquired by the US Geological Survey in 2010 and is publicly available at ifsar.gina.alaska.edu. Thanks to C. McNeil, E. Thoms, and K. Labay for helpful guidance with the data acquisition, GIS, and photogrammetry aspects of this project. Any use of trade, product or firm names is for descriptive purposes only and does not imply endorsement by the US Government.
