Velocity hazard projections at Elim, Alaska
Velocity hazards (maximum depth times velocity) from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. Velocity hazards are a measure of the velocity severity. Categories range from 0 (low hazard) to 4 (extreme hazard) following guidance from the Federal Emergency Management Agency (2020). These products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 30 storm and SLR combinations (SLR scenarios 0, 0.5, 1.0, 1.5, 2.0, and 3.0 meters combined with 1-year, 10-year, 20-year, 50-year, and 100-year storm return periods).
