Abstract: In this paper, the PPR prediction model was established and studied for the Tianshan area in Xinjiang by using the comprehensive forecasting software system of projection pursuit regression. Setting up dynamic PPR prediction model and review of prediction efficiency show that the comprehensive forecasting efficiency in the medium-and short-term earthquake prediction, especially in those areas where have enough earthquake data sample and moderate and strong earthquake cases, such as Kepin and Wuqia areas.

Key words: PPR Model, Comprehensive forecasting, Efficiency evaluation
