CHARACTERISTICS AND DISTRIBUTION OF GEO-HAZARD FACTORS IN THE WESTERN SOUTH YELLOW SEA: CHARACTERISTICS AND DISTRIBUTION OF GEO-HAZARD FACTORS IN THE WESTERN SOUTH YELLOW SEA

Marine geo-hazard factors in the western South Yellow Sea were studied based on seismic profiles.There are different types of factors which may cause geo-hazards in the study area,such as coastal erosion and siltation,submarine shoaling,shallow gases,buried paleo-channels and paleo-delta,sand ridges,steep slope,soil liquefaction,submarine deep scour channel,landslide,faults caused by differential compaction,and so on.The characters and distribution of geo-hazard factors were described and discussed based on the distribution map of main marine hazard factors we compiled.
