Abstract
Quick and reliable mapping of Tsunami hazard location and intensity
is of great importance to mankind. The conventional methods for assessing
these natural disasters rely on models that are both very time-consuming
and costly. Unfortunately, these constraints give the models no possibility
for evacuation planning to be used directly after a recorded event. This
paper presents a new method using viewshed analysis for mapping the
locations that will be affected by a Tsunami. The viewshed analysis was run from a hypothetical earthquake epicenter located 100km off the
West Coast of Vancouver Island, BC, and overlain on a Digital Elevation
Model (DEM) of Vancouver Island. Results show that Vancouver Island as
a whole is relatively safe from Tsunami attack, but some of the more
popular regions for tourists would be greatly affected and in need of
immediate evacuation.
