Abstract
|
In October 2010, the National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), developed three bathymetric-topographic digital elevation models (DEMs) of the U. S. Virgin Islands for the Pacific Marine Environmental Laboratory (PMEL) NOAA Center for Tsunami Research (http://nctr.pmel.noaa.gov/). Two 1/3 arc-second DEMs, one of St. Thomas and St. John and one of St. Croix, and a 1 arc-second DEM of the U. S. Virgin Islands region, referenced to mean high water (MHW) will be used as input for the Method of Splitting Tsunami (MOST) model developed by PMEL to simulate tsunami generation and inundation. The DEMs were generated from diverse digital datasets in the region. They will be used for tsunami forecasting as part of the tsunami forecast system. Short-term Inundation Forecasting for Tsunamis (SIFT) currently being developed by PMEL for the NOAA Tsunami Warning Centers. This report provides a summary of the data sources and methodology used in developing the Virgin Islands DEMs.
