The intensity of an earthquake is an important criterion and index for earthquake resistance, and disaster relief and for antiseismic engineering in large and medium sized cities. The earthquake data in Xinjiang are abundant and have been widely applied to the statistic relationship of seismic intensity of western China. However, there exists some unreasonable and man_made factors in them. We put forward the idea of area A_ 0-1 to express the effect of seismic intensity, studied the questions and influencing factors arising from uncertainty of intensity zoning and finally, proposed some solutions.
