Abstract Based on previous analyses, interpretation of remote sensing images and geological survey, the seismic geological environment in the Bortala region is studied and assessed. Using the deterministic seismic hazard analysis method, the trend of seismic activity is discussed. The result shows that the seismic geological characteristics of the Bortala region are similar to the South Tianshan and east part of north Tianshan regions. Both of these regions are related to the north Tianshan seismic zone, in which there exists a risk of strong earthquake.
