Investigation on damage for the Prambanan temple, housing and infrastructure was carried out in and around Yogyakarta, in central JAVA from June 5 to 8, 2006 The Prambanan complex sustained heavy damage, even this complex is located 40 km far north east of the epicenter. It is considered that the seismic wave was amplified due to the directivity effect and attacked Prambanan complex. Extensive damaged areas are distributed in the west side of the Imogiri fault. Serious damaged areas are limited in Bantul and in Klaten Regency. Damaged areas begin in Klaten Regency between Solo and Yogyakarta. In Bantul Regency, there were more than 4, 000 casualties. The infrastructure suffered comparatively light damages, however, housing sustained heavy damages and totally collapsed in Bantul Regency. In this report, reasons why the infrastructure sustained light damage while housing suffered heavily and as well as why damage areas are distributed unevenly are discussed.
