Locating the spatial distribution of a catastrophic event like tsunami and knowing its impact has
vital importance in response and recovery stages in case of emergency. To deal with this issue, not
only basic activities but also technological solutions should be used. In this sense, information about
human populations, infrastructure and other spatially distributed data can be managed by the use of
geographic information technologies. For example, the ability to provide answers to vital questions,
such as where the most affected areas are and how they can be reached, to save time in an emergency
situation, can be addressed by means of GIS technology (Goodchild, 2006).
