This paper introduces the advantages of remote sensing technology as well as several secondary seismic-induced geological disasters.And based on Ms8.0 Wenchuan Earthquake-induced geological disasters and the remote sensing data of seismic region,evaluating methods that the optical and radar remote sensing satellite data has been introduced respectively,and thematic information map has been gotten by the methods above.Finally the problem existing in the evaluation of the earthquake-induced geological disasters was summed up by remote sensing.
