What is Seismic Imaging in Fold-and-thrust Belts about?

Seismic imaging is a vital tool for mapping the complex geologic structures of the Andes. The method of imaging the Earth's subsurface with seismic waves is powerful, and it has certain limitationsdespecially when deployed in complex structure land areas like the mountain ranges and high plains of the Andes. Understanding the technologies involved and how they are applied to this specific geologic setting will improve our understanding of the risks and uncertainties involved in the interpretation of structures on seismic images. Seismic data in thrust belt environments are of typically low data density and have low signal-to-noise ratios, all while attempting to image complex geologic structures. The data are acquired over rough topography with laterally varying velocities from the surface down. If the near surface is the lens through which we image the subsurface, our lens is bumpy and distorted. These are the challenges of seismic processing in fold-and-thrust belts, and decades of technology development have gone into facing those challenges, from weathering corrections for the near-surface to advanced migration algorithms that can image below major thrust faults.
