Supplemental Information

The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships. Attribute information for each layer is included in this metadata file under the "Entity_and_Attribute_Information" section. The metadata "layer" provides the metadata, codesets, or other documentation files applicable to all layers. The data layer(s) are titled:
 >mhhw-shoreline: The present day shoreline (mean higher high water - MHHW) of the Port Valdez study area; see Grid Development and Data Sources section of the associated manuscript to learn more about how this file was created.
 >hypothetical-composite-line: Estimated, "maximum credible scenario" inundation line that encompasses the maximum extent of flooding based on model simulation of all credible source scenarios and historical observations. The "maximum credible scenario" inundation line becomes a basis for local tsunami hazard planning and development of evacuation maps.
 >hypothetical-composite-flow-depth: Raster image depicting maximum composite flow depths over dry land.
 >tectonic-scenario-01: Scenario 1. Repeat of the 1964 event: Source function based on coseismic deformation model by Johnson and others (1996);
 >tectonic-scenario-02: Scenario 2. Repeat of the 1964 event: Source function based on coseismic deformation model by Suito and Freymueller (2009) (SDM);
 >tectonic-scenario-03: Scenario 3. Multi-Segment JDM event: Source function based on extension of the JDM;
 >tectonic-scenario-04: Scenario 4. Multi-Segment SDM event: Source function based on extension of the SDM;
 >tectonic-scenario-05: Scenario 5. Rupture of the Yakutat-Yakataga segment;
 >tectonic-scenario-06: Scenario 6. Rupture of the Cascadia zone, including portions of the margin along the British Columbia and northern California shores;
 >tectonic-scenario-07: Scenario 7. Modified 1964 event: Prince William Sound asperity of the JDM;
 >tectonic-scenario-08: Scenario 8. Modified 1964 event: Kodiak asperity of the JDM;
 >tectonic-scenario-09: Scenario 9. Modified 1964 event: Prince William Sound asperity of the SDM;
 >tectonic-scenario-10: Scenario 10. Modified 1964 event: Kodiak asperity of the SDM;
 >tectonic-scenario-11: Scenario 11. Modified multi-segment JDM event: Rupture of the PWS and YY segments;
 >tectonic-scenario-12: Scenario 12. Modified multi-segment SDM event: Rupture of the PWS and YY segments;
 >tectonic-scenario-13: Scenario 13. Mw8.8 earthquake in the Gulf of Alaska region: 17-30 km (10.5-18.6 mi), uniform slip along strike;
 >tectonic-scenario-14: Scenario 14. Mw8.8 earthquake in the Gulf of Alaska region: 13-28 km (8.1-17.4 mi), variable slip along strike;
 >tectonic-scenario-15: Scenario 15. Mw 8.8 earthquake in the Gulf of Alaska region: 12-29 km (7.5-18 mi), variable slip along strike;
 >landslide-scenario-16: Scenario 16. Repeat of the 1964-type event: An underwater slide at the head of Port Valdez (HPV slide);
 >landslide-scenario-17: Scenario 17. Repeat of the 1964-type event: An underwater slide at the Shoup Bay moraine (SBM slide);
 >landslide-scenario-18: Scenario 18. Hypothetical event: An underwater slide offshore of Mineral Creek (MC slide);
 >landslide-scenario-19: Scenario 19. Hypothetical event: An underwater slide offshore of Gold Creek (GC slide);
 >landslide-scenario-20: Scenario 20. Hypothetical event: An underwater slide offshore of Lowe River (LR slide);

Metadata

Metadata is the data about the data and answers "Who, what, when, where, how and why?" about the dataset. Please see the DGGS Metadata README page for information about our metadata.

Use Constraints

This dataset includes results of numerical modeling of earthquake-generated tsunami waves for a specific community. Modeling was completed using the best information and tsunami modeling software available at the time of analysis. They are numerical solutions and, while they are believed to be accurate, their ultimate accuracy during an actual tsunami will depend on the specifics of earth deformations, on-land construction, tide level, and other parameters at the time of the tsunami. Actual areas of inundation may differ from areas shown in this dataset. Landslide tsunami sources may not be included in the modeling due to unknown potential impact of such events on a given community; please refer to accompanying report for more information on tsunami sources used for this study. The limits of inundation shown should only be used as a general guideline for emergency planning and response action in the event of a major tsunamigenic earthquake. These results are not intended for any other use, including land-use regulation or actuarial purposes. Any hard copies or published datasets utilizing these datasets shall clearly indicate their source. If the user has modified the data in any way, the user is obligated to describe the types of modifications the user has made. The user specifically agrees not to misrepresent these datasets, nor to imply that changes made by the user were approved by the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys. The State of Alaska makes no express or implied warranties (including warranties for merchantability and fitness) with respect to the character, functions, or capabilities of the electronic data or products or their appropriateness for any user's purposes. In no event will the State of Alaska be liable for any incidental, indirect, special, consequential, or other damages suffered by the user or any other person or entity whether from the use of the electronic services or products or any failure thereof or otherwise. In no event will the State of Alaska's liability to the Requestor or anyone else exceed the fee paid for the electronic service or product.
