APPROACH ON GEOHAZARDS RISK MANAGEMENT |FOR URBANS IN STRONG SEISMIC ZONE

Risk management of geohazards is a cognition and model of effective disaster mitigation in order to make recommendations for prevention, preparedness and response. The increased vulnerability and risk of many urban areas in strong seismic zone is a major reason for these areas suffering from more serious damage. This paper discusses some main aspects concerning risk management which involves risk analysis, action preparedness and disaster response for urban geohazard mitigation in strong seismic zone. Therefore, the research of risk management of geohazards becomes an important project for urban geohazard reduction. This paper describes the advances in risk management of geohazards and puts forward the future study contents and methodology. They involve in five aspects: (1) risk structure and risk quantizing analysis of urban geohazards in strong seismic zone; (2) establishment in risk criterion and risk principle of urban seismic geohazards; (3) study on methodology of risk management of urban geohazards in strong seismic zone; (4) effective monitoring and control mechanism for risk management of urban seismic geohazards; (5) study on patterns and systems for risk management of urban geohazards in strong seismic zone.
