Indonesia is an area that is very vulnerable to the impacts of earthquake hazards, including in the Yogyakarta Special Province (YSP). According to [1] the earthquake hazards in particular area as well as the development of the Building Codes can be developed by carrying out the Probabilistic Seismic Hazard Analysis (PSHA) even though verifying the results as compare to the actual earthquake occurrence still need to be investigated. The seismic hazard map of the superseded Indonesian Seismic Codes was developed by applying 10 % Probability of Exceedance (PE) during 50 years, however, the current Codes was based on 2 % PE during 50 years. It is necessary to compare the PSA between two Codes. The probabilistic seismic hazard analysis (PSHA) at YSP with 10% and 2/3 of 2% PE for 50 years has been conducted. The PGA at the ground surface is done based on VS30 published by USGS. The results of the analysis showed that by using more complete earthquake data, all PSA values obtained were slightly higher than the results as presented by [2] and PSA values of 2/3 of 2% PE are significantly greater than PSA based on 10% PE during 50 years
