Abstract
Tsunami inundation models provide fundamental information about coastal areas that may be inundated in the event of a tsunami. This information has relevance for disaster management activities, including evacuation planning, impact and risk assessment, and coastal engineering. A basic input to tsunami inundation models is a digital elevation model-that is, a model of the shape of the onshore environment. Onshore DEMs vary widely in resolution, accuracy, availability, and cost. Griffin et al. (2012) assessed how the accuracy and resolution of DEMs translate into uncertainties in estimates of tsunami inundation zones. The results showed that simply using the 'best available' elevation data, such as the freely available global SRTM elevation model, without considering data accuracy can lead to dangerously misleading results.
