Abstract
A tsunami warning system based on active database system with satellite derived real-time data of tidal, significant wave height and ocean wind speed as well as assimilation data of sea level changes as one of the global risk management systems is proposed. Also, Geographic Information System (GIS) with free open source software of PostGIS is proposed for active database system. It may be said that the proposed tsunami warning and evacuation information provided system is recommendable.
Highlights
There is a strong desire for disaster warning systems to mitigate disaster as well as secondly disaster, for the warning systems for earth quake, tsunami, flooding, hurricane and so on

Summary
There is a strong desire for disaster warning systems to mitigate disaster as well as secondly disaster, for the warning systems for earth quake, tsunami, flooding, hurricane and so on. The system for making warning should include the followings: 1) gathering disaster related data as a data stream, 2) calculating and extracting information for making decision of warning from the data stream, and 3) transmit the warning information to the peoples who are living in the dangerous areas which contains information for evacuation as well as disaster recovery For such warning systems need the followings: Active database systems [1]. Coastal hydraulic modeling system receives sea level changes data from the measuring towers at regular interval in a real-time basis. This data is used for forecasting wave height and direction at different locations along with the coastline. If the tower is set along with the possible coastal areas, disaster due to tsunami might be mitigated
