  • This paper aims to analyze some vague problems in sudden geohazard prediction and evaluation, propose a guideline for geohazard and risk assessments in China and try to combine the theory and techniques of landslide risk assessments and management abroad and sudden geohazard evaluation at home. On the basis of a brief analysis of the basic concepts, structure levels and core content of sudden geohazard prediction and evaluation, the focus is put on the study of the work procedures of sudden geohazard prediction and evaluation The paper emphasizes the importance of baseline information inventory, advocates grading of basic work quality and preliminarily proposes the grounds for levels of detailedness of baseline information. Emphasis is placed on qualitative analysis and quantitative statistics and integration of simulating calculation with evaluation; the popularization of the practical techniques and GIS technique is promoted; the basic principles of geohazard vulnerability, danger and risk evaluation zoning, practical methods and standards of geohazard grading are put forward.Finally, four key issues of geohazard prediction and evaluation are briefly discussed.
