Passive seismic tomography using surface-wave extraction

  • Health and safety
  • Land-use planning
  • Permitting processes / policy integration
  • Reporting official statistics
  • Socio-economic and environmental impact assessments

Challenge the practice is addressing: The practice is addressing the relatively new technique that uses recorded seismic noises in order to improve exploration efficiency at depth. In contrast to active seismic methods, the passive seismic approach is cheaper, less environmentally destructive and more efficient method. The passive method using surface wave extraction has been used to for regional tomographic imaging to provide information on near-surface geological structures at a local scale.

Concrete practice to achieve the expected goal: The practice is divided into four phases: single station data preparation, cross-correlation and temporal stacking, measurement of dispersion curves and quality control including an error analysis

Expected impact/goal of the practice: The practice has been successfully used to retrieve reflection images using as a cheaper and less environmentally destructive approach than the active seismic method.

Who is the target user group of the practice/intervention or implementing the practice/intervention? This practice is particularly used to improve methods within companies in the mining industry.
