Tsunami inundation maps of Port Valdez, Alaska

We evaluate potential tsunami hazards for the city of Valdez and numerically model the extent of inundation from tsunamis generated by earthquake and landslide sources. Tsunami scenarios include a repeat of the tsunami triggered by the 1964 Great Alaska Earthquake, as well as hypothetical tsunamis generated by an extended 1964 rupture, a Cascadia megathrust earthquake, and earthquakes from the Prince William Sound and Kodiak asperities of the 1964 rupture. Local underwater landslide events in Port Valdez are also considered as credible tsunamigenic scenarios. Results of numerical modeling are verified by simulating the tectonic and landslide-generated tsunamis in Port Valdez observed during the 1964 earthquake. The results of these tsunami scenarios are intended to provide guidance to local emergency management agencies in tsunami hazard assessment, evacuation planning, and public education for reducing future casualties and damage from tsunamis.

High-resolution lidar data for infrastructure corridors, Bettles Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (Light Detection and Ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The dataset represents ground-classified laser returns from the lidar survey and their associated geospatial coordinates.

Preliminary characterization of two coals from the upper Prince Creek Formation, Sagwon Bluffs, North Slope, Alaska

In July of 2018, the Alaska Division of Geological & Geophysical Surveys (DGGS) studied and sampled the coal beds within the upper section of the Prince Creek Formation at Sagwon Bluffs. Sagwon Bluffs lies 55 miles south of Deadhorse (Prudhoe Bay), Alaska, and approximately one mile east of the Dalton Highway, on the west side of the Sagavanirktok River. At Sagwon Bluffs, Upper Cretaceous to Paleocene rocks of the Prince Creek and Sagavanirktok Formations are exposed. The upper Prince Creek Formation at this location contains several distinct coal seams interbedded with fine-grained fluvial sandstone. A lower coal seam and an upper seam were channel sampled for this study. This Preliminary Interpretive Report presents results from coal quality (proximate and ultimate analysis), Rock-Eval, vitrinite reflectance, and kerogen microscopy analyses. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30556.

Photogrammetric digital surface models and orthoimagery of Vine Road, December 5, 2018

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) produced digital surface models (DSMs) and orthorectified aerial imagery (orthoimagery) over selected locations in the greater Anchorage area following the Mw 7.1 November 30, 2018, Anchorage earthquake. We selected areas of interest (AOIs) based on initial damage reports from the Alaska Department of Transportation & Public Facilities (DOT&PF) and the United States Geological Survey (USGS) in order to document earthquake effects. Aerial photographs collected December 5-6, 2018, were processed using Structure-from-Motion (SfM) photogrammetric techniques to create sub-meter DSMs and orthoimagery. This digital data set covers Vine Road and was collected on December 5, 2018. These data document ground conditions immediately following the 2018 Mw 7.1 Anchorage earthquake. For the purposes of open access to elevation and orthoimagery data sets throughout Alaska, this collection is being released as a Raw Data File with an open end-user license.

Palynological and thermal maturity analysis of outcrop samples from the Kenai, Seldovia, and Tyonek quadrangles, Cook Inlet region, Alaska

This data release provides palynomorph assemblages, kerogen observations, thermal maturity estimates, age interpretations, and field station locations of palynology samples collected (2006-2011) from measured stratigraphic sections and key middle Eocene to early Pliocene sedimentary rock outcrops throughout the Kenai, Seldovia, and Tyonek quadrangles. Palynological analysis of surface rock samples offers supporting data for geologic mapping and stratigraphic research conducted by the Alaska Department of Natural Resources' (Alaska Division of Geological & Geophysical Surveys [DGGS] and Alaska Division of Oil & Gas [DOG]) Cook Inlet Basin Analysis Program. The Cook Inlet program provides publicly available baseline outcrop data and geologic findings from the petroleum source, seal, and reservoir rocks of the prospective Cook Inlet hydrocarbon basin. Program products inform interpretations of the geologic processes that shaped the petroleum system's basin evolution.

Surficial geology of the Tyonek area, south-central Tyonek Quadrangle, Alaska

The Tyonek area in the northwestern Cook Inlet trough is rich in petroleum, coal, geothermal, aggregate, and timber resources, but the detailed geologic mapping necessary for planning future resource development exists only in part of the area. This report and geologic map provide basic surficial-geologic information useful for exploiting those resources and planning future utility corridor developments. In addition to mapping of surficial geologic units, we provide discussion of strategraphic evidence pertaining to physiographic relations and geologic history of volcaniclastic deposits derived from ancestral Mount Spurr, multiple phases of Quaternary glacial activity, Chakachatna River valley landslide complexes and debris avalanches, the Kaloa deposits in northwestern Cook Inlet, Lake Clark fault, and holocene flooding in the Beluga, Chichantna, Chakachatna, and McArthur river drainages.

Shoreline change at Alaska coastal communities, Nome, Alaska

The Division of Geological & Geophysical Surveys has analyzed long-term shoreline change at 48 Alaska communities. Shoreline datasets were compiled from previously published U.S. Geological Survey assessments and created from historical and recent aerial images by the Alaska Division of Geological & Geophysical Surveys. Shorelines were analyzed to calculate shoreline change rates every 25 meters along coastlines and tidally influenced riverbanks using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018). The geodatabase for each community includes shoreline positions, the alongshore baseline used to cast transects, and transects that include shoreline change rates and statistics. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30552).

Photogrammetry-derived digital surface model and orthoimagery of land areas near Resurrection Bay, Alaska

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) produced a digital surface model (DSM) and an orthorectified aerial optical image mosaic (orthoimagery) of the Resurrection Bay watershed, surrounding the city of Seward in south-central Alaska. Aerial photographs and Global Navigation Satellite System (GNSS) data were collected on August 13, 2015, and were processed using Structure-from-Motion (SfM) photogrammetric techniques to create the DSM and orthoimagery. All data are projected in UTM Zone 6 North (meters) using the NAD83 (2011; EPSG 26906) horizontal datum and NAVD88 (Geoid12A; EPOCH 2010.00) vertical datum. The project was part of an ongoing investigation of the impact of flooding, slope instability, and cryosphere hazards on infrastructure and public safety. For the purpose of enabling open access to geospatial datasets in Alaska, this collection is being released as a Raw Data File with an open end-user license. All files can be downloaded free of charge from the DGGS website (http://doi.org/10.14509/29824). The orthoimage is a three-band, 8-bit unsigned GeoTIFF file using LZW compression. The orthoimage has a GSD of 0.2 m per pixel, and the No Data value is set to 0. Variable lighting in the orthoimages may result from variable sky conditions during the time of data acquisition.
