Abstract: With the development of ocean exploration and utilization,the ocean countries are struggling for implementation of new ocean strategies. As one of the natural disasters,marine geologic hazards have raised great attention recently from governments and the public. Based on the approximately 3 000 km of high resolution shallow seismic profiles,recently acquired from the coastal and offshore area of southern Shandong Peninsula,this paper deals with the main potential marine hazardous geological factors with special emphasis on the distribution,formation, risk and burial characteritics of some of the factors,such as irregular bedrock,burial paleo-channel,shallow gas and fault. Meanwhile,the geohazard map of the study area has been completed. The scientific information incurred could be used for marine resource exploitation and engineering construction.
