I’m a senior engineer of National Institute of Natural Hazards, Ministry of Emergency Management of China. Our research group aims to unravel the intricate interactions between human systems and extreme natural settings by investigating similar composite disaster events. Employing a systemic perspective, we analyze human activities during the phases of early warning, response, and disposal. Our dedication is to identify pivotal factors contributing to substantial loss of life during different stages of the disaster process, including low standard flood control projects, inefficient organization and preparedness by local government entities, inadequate emergency response measures from various departments, and a lack of readiness among the local populace.
