1 Decision Support System for Earthquake Disaster Management, study case in Indonesia Spits Warnars Department of Computing and Mathematics ,Manchester Metropolitan University John Dalton Building, Chester Street, Manchester M1 5GD, United Kingdom s.warnars@mmu.ac.uk Abstract : On our earth there are 8000 earthquakes per day, as one of the threat for people around the world and Indonesia has more than 30 quakes predictions per day as one of the threat for Indonesian. We can not avoid the disaster but we can decrease the victim and lost by learning from the past earthquake. DSS is information technology environment which can be used to help human in order to learn from past earthquake, record it, learn and plan for future mitigation and hope will reduce the disaster risk in the future. Using web technology for DSS will give value added where not only make a strategic decision for the decision maker, but for others who need national earthquake information like citizen, scholars, researches and people around the world. DSS for earthquake disaster management will be more powerful if linked to other disaster DSS as a part of National disaster management which be linked with other government institution and international. Datawarehouse as unNormalized database for multidimensional analysis will speed the query process and increase reports variation for the DSS.

Introduction Around Sept- Oct 2009 there are 6 high magnitude earthquakes which hit Indonesia[18], start from Tasikmalaya, 2 sept 2009 with 7.3 SR, Yogya, 19 Sept 2009 with 6.4 SR, Denpasar, 19 Sept 2009 with 6.4 SR, Pariaman, 30 Sept 2009 with 7.6 SR, Saumlaki, 24 Oct 2009 with 7.3 SR and Waingapu, 25 Oct 2009 with 6.1 SR. These are proof how Indonesia is a vulnerable country which has earthquake as one of threat. This horrible incident remember us in Indonesia about Aceh’s quake on Dec 26 Th ,2004 where 9.1 on the Richter scale earthquake just off the west coast of the island of Sumatra, and the tsunami that followed, killed at least 230,000 people in 12 countries, including about 168,000 in Indonesia alone. Aceh’s quake was listed as the 12 of the most destructive earthquakes [3]. After Aceh’s quake many earthquakes have struck Indonesia alternately and even other disasters have been a threat for every citizen in this country. Actually an everyday occurrence on earth and more than 3 million earthquakes occur every year, about 8,000 a day, or one every 11 seconds [13] in Indonesia there are 5 to 30 quakes prediction everyday [10]. Government’s responsibility to protect the citizen has been done by making National body of disaster management [4][5]. Preparing, saving and distribution logistic become National body of disaster management’s responsibility to build information management [11; article 18,26]. Many law’s products have been produced as a government’s responsibility to give secure life for the citizen. We can not prevent them totally, we have to learn to live with them and need to be prepared all the time, need to learn how to mitigate risk of losses in such events by managing crisis and emergencies correctly[16]. After disaster happens respond must be rapidly and at an optimal level to save lives and help to victims. 2. Problem identification Government have responsibility to declare disaster management start from pre disaster, on disaster and after disaster [2][4].
