Frequency Analysis and Sismic Vulnerability Index by Using Nakamura Methods For Microzonation at Prambanan Temple and Its Surrounding Area, Yogyakarta Province, Indonesia

A seismic vulnerability index ranging from 0.1 to 28 was identified for the Prambanan Temple Complex and its surrounding area, indicating significant variability in earthquake risk across the region. This finding stems from a microzonation study using Nakamura's method, which analyzed dominant frequencies (0.2–21 Hz) and amplification factors (0.2–7) derived from 60-minute seismograph measurements at 89 points spaced 1000 meters apart. The research, conducted in response to the devastating 2006 Yogyakarta earthquake that damaged nearby temples, provides critical data for assessing seismic vulnerability and guiding mitigation efforts in culturally significant heritage sites.
