The devastating earthquake on 27 May 2006 measured at 5.9 Richter scale has caused serious problems in Yogyakarta and Central Java, Indonesia. The earthquake destroyed more than 200,000 houses and 6,000 casualties. One important concern in managing the disaster is the importance of information dissemination. It is important to distribute accurate and timely updated information for any needs, such as logistic distribution. Disaster management team of the Department of Geodesy and Geomatic Engineering (DGGE), Gadjah Mada University (GMU) considered the need to establish a spatial-based disaster information system, which is publicly accessible. The information should contain number of casualties, number and level of building damage, and logistics that have been distributed. The information can be utilized to enhance the effectiveness and efficiency of logistic assistance distribution. The system also enables users to conduct spatial analysis such as distant measurement and to define access to certain location.A web-based Geographic Information System for Yogyakarta, Indonesia has been created by DGEE team. The GIS has been made available online in the website of Department of Geodesy and Geomatic Engineering, www.geodesi.ugm.ac.id. The system provides timely-updated information with data collected by field survey team of DGGE in collaboration with Yogyakarta local government.Keywords: tectonic earthquake, disaster management, web-based GIS
