Typhoon triggered operation tunnel debris flow disaster in coastal areas of SE China

Abstract Typhoons have inflicted significant damage and loss of life to China, a large number of typhoon–rainstorm–debris flow–tunnel accidents occur in the southeastern coastal areas each year. Considering the disaster prevention and mitigation decision-making of disaster accidents in coastal areas and the reduction of regional economic losses, this Express Letter presents some typical accident scenes and rescue measures in recent years and analyses the hazard mechanism from three aspects. On this basis, we propose some suggestions such as the monitoring and early-warning system, which can provide a few references for reducing disaster losses and improving disaster treatments
