Abstract
Various disaster information systems have been introduced to central and local governments. However, the usability of such an information system supporting disaster response management in practical use has not been necessarily sensible. In order to cut down the above-mentioned problem, the authors developed a practical disaster response manaegent system for a local government and it has been applied to Mitsuke City, Niigata Prefecture.
In this paper, 9 improvement issues on usability of the disaster response management system were extracted through workshops previously conducted in Mitsuke City. Then, the system was renewed by making those improvements. The validity of those improvements was proved through an evaluation test .
