Web-based Tsunami Visualization

چکیده
The Indonesian tsunami in December 2004 awakened the world to the need to better understand and predict tsunami wave behavior using simulations. In order to understand such an immense amount of data, a visual approach was desired. This paper describes a visualizer for tsunami wave simulations. The Tsunami Visualization and Animation Tool (TVAT) works with multiresolution wave height and bathymetry depth files. It animates the wave simulation, and allows the user to probe the waves to see a plot of wave heights in time or along a transect in space. TVAT is written in Java using Java OpenGL (JOGL) so that it can be run standalone or as a web applet. It also uses GPU programming to speed the display. The methods developed and lessons learned from this project can be applied to many other large-dataset visualization projects.

Modeling and Visualization of Tsunamis
Modeling tsunami wave propagation is a very challenging numerical task, because it involves many facets: Such as the formation of various types of waves and the impingement of these waves on the coast. We will discuss the different levels of approximations made in numerical modeling of 2-D and 3-D tsunami waves and their relative difficulties. In this paper new attempts are proposed to evaluate...

متن کاملHarmonization of data formats for tsunami simulation products
The development of sustainable tsunami early warning systems (TEWS) requires the adoption of proven standards for components on all system levels. This is crucial to ensure the successful operation of the overall system in the long term. Currently, components, data formats and models used to build an individual TEWS come from independent development efforts, using non-standardized proprietary i...
