province of Yogyakarta, which caused considerable damage. This
is the basis need to investigate the seismic vulnerability index in
around of the earthquake zone. This research is called
microzonation of earthquake hazard. This research has been
conducted at the site and surrounding of Prambanan. The reason
this research needs to be done because in the event of an
earthquake in 2006, there was damage to the temples at
Prambanan temple complex and its surroundings. In this
research, data collection carried out for 60 minutes using three
component seismograph measurements at 89 points with spacing
of 1000 meters. The data recorded in time function were analyzed
using the spectral ratio method, known as the Horizontal to
Vertical Spectral Ratio (HVSR). Results from this analysis are
dominant frequency (F
g
) and amplification factor (A
) are used
to obtain seismic vulnerability index. The results of research
showed the dominant frequency range from 0.2 to 21 Hz and the
amplification is in interval from 0.2 to 7. Interval value for
seismic vulnerability index is 0.1 to 28.
Keywords – amplification factor, dominant frequency,
microzonation, seismic vulnerability index.
