Natural disasters such as earthquakes and tsunamis have constantly proved the fragility of infrastructures and shown the complexity of strong ground motion generation. To reduce the vulnerability of infrastructures, numerous methodologies have been developed to extract detailed information from the earthquake source mechanism to provide rational earthquake hazard information and use it as input for structural vulnerability assessment. A common practice after a destructive earthquake occurs is to observe and analyse the damage mechanisms on the structures distributed in the damage zones, aiming to comprehend and infer the process and reasons for such destructive damages. To later upgrade the seismic standards for structural analysis and engineering design practices from the outcomes of the lesson learned from this devastating experience, to level up decision-making associated with diagnosis and strengthening of vulnerable infrastructures, and to contribute to decision-making related to strengthening of infrastructures, susceptible to earthquake damages, we proposed an earthquake damages detection methodology for unseen underground bridge infrastructures based on transfer resistance as essential measurement, and combined along with seasonal external effects, and error analysis; to consider the dispersive and propagation nature of uncertainty, and account for correction factors, respectively. To unravel the dimensional and intrinsic error associated with the fracturing area within the foundation and observed over the residual power spectrum. In general, we detected the earthquake damage zone when the reinforcement mesh was exposed and surpassed by the rupture zone.
