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 and correspond to subdirectories within the data distribution package. The metadata layer provides the metadata or other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents:
>mhhw-shoreline: The present day shoreline (mean higher high water - MHHW) of the Sitka study area; see Grid Development and Data Sources section of this report 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. For each grid point, the pixel value provides the modeled depth of water (in meters) over previously dry land, representing the maximum depth value of all calculated tsunami scenarios.
>tectonic-scenario-01: Scenario 1. Multi-Segment event based on the JDM (PWS, KP, KI, and YY segments)
>tectonic-scenario-02: Scenario 2. Multi-Segment event based on the SDM (PWS, KP, KI, and YY segments)
>tectonic-scenario-03: Scenario 3. Modified multi-segment event: rupture of the PWS, KP, and YY segments of the JDM
>tectonic-scenario-04: Scenario 4. Modified multi-segment event: rupture of the PWS, KP, and YY segments of the SDM
>tectonic-scenario-05: Scenario 5. Multi-Segment event: the Tohoku-type rupture of the PWS, KP and KI segments
>tectonic-scenario-06: Scenario 6. The SAFRR tsunami scenario (SEM and SH segments)
>tectonic-scenario-07: Scenario 7. Rupture in the Eastern Aleutians, from Semidi Islands to Fox Islands (SEM, SH, UN and FOX segments)
>tectonic-scenario-08: Scenario 8. Rupture on the Cascadia subduction zone
>tectonic-scenario-09: Scenario 9. Mw8.2 thrust earthquake in the Haida Gwaii area
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.
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.
