| Abstract: | The result of the investigation by sub-strata profiler shows that there are many geohazard factors in the South Yellow Sea, such as tidal ridge group, ravin eroded by strong tidal currents, sub-marine gully and rough seabed, mud dune and steep slope, mud flow, buried paleo-channel, buried paleo-lake, buried paleo-delta, active fault and shallow gas. According to their locations and endangering effects, geohazard factors can be divided into two types: sea floor geohazard factors and underground geohazard factors. Based on dangerous degree, each type of geohazard factors could be divided into dangerous and constraint factors which could be further divided into immediate and latent (induced) geohazard factors. Based on assemblages of geohazard factors, the investigation area could also be divided into various geohazard zones asfollowing: immediate sea floor hazard zone, latent sea floor hazard zone, immediate sea floor constraint zone, sea floor non hazard zone, immediate underground hazard zone, latent underground hazard zone, underground constraint zone and underground non hazard zone. |
