Arias Intensity is a ground motion parameter that contains amplitudes, frequencies, and duration of ground motion. It is more reliable in some predictions of seismic damage than the parameters that only depend on the amplitude of ground motion. Scientists have shown that Arias Intensity has a strong correlation with landslides induced by earthquakes. This study presents a preliminary probabilistic seismic hazard assessment in terms of the Arias Intensity in Danling County, Sichuan Province using a seismic source model and the seismicity model established by the Seismic Ground Motion Parameters Zonation Map of China. The results show that the I_a value for most of Danling County and its surrounding area is above 0.11 m/s. Some parts of the area has a value of 0.32 m/s. Some even has more than 0.54 m/s, where a relatively high hazard of earthquake-induced landslides can be found. Hence, we should strengthen the risk assessment of earthquake-induced landslides in personnel concentration areas. An obvious difference is found in the calculation of the I_a distribution according to different I_a prediction equations. Therefore, we should consider more than one I_a prediction equation when calculating the I_a value. The weighted average of the final results is derived to reduce the uncertainty of the I_a value. We also find a strong correlation between I_a and spectral acceleration (t=1.0 s), which confirm the correlation between sand liquefaction and I_a.
