【 摘 要 】

A study has been conducted to understand effect caused by earthquakes in Aceh. Using earthquake data from ISC, probabilistic seismic hazard analysis has been done to obtain informations how is the effect caused by earthquake sourced near Aceh. The results are peak ground acceleration, spectral acceleration for period of 0,2 and 1 Hz within return period 500 and 2500 years which equal to probability of exceedance 10% in 50 years and 2% in 50 years. There are several differences compared to results of study that had been conducted by Pusgen earlier in 2017. The results might be used as preliminary information to illustrate level of seismic hazard in Aceh.
