Induced Seismicity in Fox Creek, AB: Amplification Function and Foundation Factors

ABSTRACT: The increase in induced seismicity in the Fox Creek AB area has triggered the interest in site amplification for sites characterized by shallow rock. A new methodology to characterize the thin soil sites amplification is presented in this paper and is based on the characterization of the linear (initial) site fundamental period of vibration. The methodology is applicable to sites where soil having shear wave velocities smaller than 300 m/s overlay soft rock characterized by shear wave velocities between 360 and 760 m/s, typical of site C conditions. Amplification functions for hazard studies and foundation factors for engineering applications are developed and proposed to characterize the surface ground motion.
