Passive seismic surveys use natural seismic waves from to study the Earth's internal structure. Providing data from shallow levels, through the crust and the lithosphere/asthenosphere boundary (LAB) to the core, passive seismic surveys help to determine seismic risk and hazard, identify areas of mineral prospectivity, unravel tectonic history and inform land-use planning.
It works by detecting seismic waves from earthquakes, both local and global, but also more continuous sources such as the pounding of ocean waves and storms.
