HVSR and Site Characteristics of the Seismic and Strong-Motion Stations in Gansu Province, China
Abstract
The horizontal-to-vertical spectral ratio (HVSR) method for seismic site characterization using microtremor and earthquake recordings has been widely employed since its introduction in 1989. We applied HVSR to analyze seismic and strong-motion earthquake S-waves in the Gansu province, China. The seismic stations were bedrock installations, whereas the strong-motion stations were installed on soils throughout the Province. Results show that most of seismic stations have no obvious predominant peak, but the strong-motion stations exhibit predominant peaks. Therefore, we corroborate HVSR as a cost-effective method to characterize ground-motion site effect caused by the near-surface soils.
