This manuscript presents a new model, named SY model, to predict horizontal peak ground acceleration and 5% damped response spectrum for shallow crustal earthquakes in Sichuan-Yunnan region of China. SY model considers the influences of magnitude, rupture distance, fault types, site amplification and hanging-wall scaling on ground motions. The random effect regression analysis and residual analysis are used to fit SY model based on a strong-motion database which is established to summarize the recordings of Sichuan-Yunnan region shallow crustal earthquakes. Prediction results are provided by SY model and subsequently compared with observations and those of other GMPEs for validation.
