Abstract
Integrating GIS to Analyze Historic Tsunami Impacts on Coastal Landforms
Track: Ocean, Coastal, and Marine Resources
Author(s): Franziska Whelan
Repetitive, catastrophic tsunamis have been credited as a causative mechanism for geomorphic change in coastal landforms. This project analyzes tsunami evidence on the Hawaiian Islands using ArcView, Spatial Analyst, and 3D Analyst. GIS advances now allow complex characteristics of coastal landforms indicating tsunami impact to be comprehensively mapped and analyzed. 'Signature' remnants of massive historic tsunamis, such as dislocated large boulders and conglomerates, provide evidence for historic tsunami events and their magnitude. GIS and remote sensing data sets, such as high-resolution orthoimagery and LANDSAT imagery, permit spatial analysis of coastal landscapes for evidence of these high magnitude, low frequency events.
