Abstract

A devastating earthquake of magnitude 6.4 that struck Central Java, Indonesia, on May 27, 2006 affected a number of architectural heritages in and around the one of the historic cities in Indonesia, Yogjakarta. The serious damage that attracted world wide concern immediately after the earthquake was to the Prambanan Temple Compounds, World Heritage of stone structures. As the Indonesian government requested in emergency the cooperation of Japanese Government to assess the earthquake damage to the Prambanan Temples for starting the restoration project, an interdisciplinary team of Japanese experts was organized in collaboration of Indonesian experts and has been conducting structural architectural survey for three years in consideration of ISCARSAH guideline. This international cooperative project is introduced as a successful case study of seismic assessment of the stone monuments damaged by the recent devastating earthquake in Asia.
The scope of the present paper is 1) to briefly review the unique history of the Prambanan Temples from a structural point of view, 2) to outline the features of the earthquake damage, 3) and to describe the architectural structural survey of the stone temples for the restoration. In particular, it focuses both on the structural analysis to clarify the cause of the earthquake damage for designing the structural strengthening and on the structural monitoring to assess the present state of the stability. As the structural monitoring, monitoring of earthquakes, as well as, that of crack displacement have been conducted.
