Course Syllabus


Waves of elastic energy travel through the Earth with the same physical principles as other waves travel through different mediums.  This video focuses on the physics of traveling waves and why energy absorption is important to an understanding of seismic data. Starting with a linear second-order vibrating system as a mathematical model, the 50-minute short course presents the classes of waves and their associated measurements. The basics of energy loss in traveling waves are described, as well as the relationship between vibration and energy loss. A simplified model of the seismic geophone is used to described attenuation and damping ratio. Other concepts covered include

  • Attenuation coefficient
  • Damping ratio
  • Relative bandwidth
  • Strain energy fractional loss
  • Seismic attributes for attenuation
  • Q as an internal rock property
