Abstract: We have used some new techniques to study the modern eruption scale of the Tianchi Volcano in Changbaishan Mountain. They include analysing the remote sensing data, GIS, multisource data fusion, orthogonal cross-course wavelet transform and the BP neural network method. The geological investigation and dating data are incorporated in the analyses. The results will be helpful for the volcanic hazard assessment.
