Abstract: The Cangdong Fault runs through the main urban area of Cangzhou. In order to explore the seismic performance of the buildings around the fault, an investigation of buildings within 2.5 kilometers of the fault was conducted. The investigation contents mainly include building structure, building age, building seismic measures, resident population, etc. Through the investigation, a seismic performance model of buildings in the area was established and key hidden hazard points were identified. Earthquake prevention and disaster mitigation countermeasures were proposed for seismic fortification.
