The DSS as E-government implementation can make comfortable for the citizen about their government's attention for protection upon their live and business. People can access what standard procedure must be declared and done by government to protect their live and business. The standard procedure will distinguished in many different levels disaster's situation and different type of disasters. By clear standard procedure the citizen will quiet in their daily live and business and there is no fluctuation which can disturb the national economy when the disasters have come. The national economy will recover in short time or even will not be influenced when the disasters have come. For the real economic sector, the right handle for the disturbance will have no effect. The bad issue in shortly will bring the fluctuation but bad issue will have no effect if there are some good information.

which combine software, hardware and technology in order to deliver the information as support for decision making. Earthquake DSS as an E-government application will be developed with web technology. E-government will make the system which can be accessed from anywhere and anytime in transparency and accountability. Earthquake DSS 
application can be built with: 1) Client programming like HTML, Javascript or Jscript, Code Style Sheet, and Java Applet. 

2) Server Programming like ASP, PHP, JSP, 
coldfusion or CGI 
3) Database can use such as MySQL, Oracle, SqlServer, or postgrace. 

The choosing for server programming and database technology will depend on agreement, optional to choose between proprietary or open source. For web hosting service will appoint an approved ISP (Internet Service Provide). 

For delivering the information multimedia is an important thing, all the multimedia elements like text, sound, picture, graphic art, animation and video must be included in it. Application and database will be divided into 2 servers for performance and for security there will be needed firewall to control every access. Specifically for database server will have 2 kind of databases are Datawarehouse as UnNormal Structure database for multidimensional analysis, save all information, past data, archive, external data as hypercubes [6]. Transactional is database support for earthquake DSS transaction.

Fig 3. Earthquake DSS architecture Reports on clients will be delivered both text and chart and can be viewed with many variant and multi dimensional. Drilldown, Roll up, slice and dice is way to show multidimensional in hypercubes. ETL 
(Extraction, Transformation and Loading) 
application can be put in database server which automatically will extract data from transactional and external database into datawarehouse. For performance and not disturb the process then data will be captured in Deferred data extraction base on Date and time stamp [6]. For datawarehouse dimensional model will be used snowflake schema. Kinds of user like miners, explorers, farmers, tourists and operators may access the datawarehouse 
[6]. 

Datawarehouse earthquake DSS record the disaster location, quantity of victim, infrastructure and property damage [11, article 22]. The Quake table is a fact table which record date, time, longitudinal, latitude, magnitude, epicenter, length, and area of quakes. Other tables is dimensional tables. Quake table will have connection with Stasiun Quake table as table list of earthquake station[10]. To make easy to record area of
