Advances in Seismic Interferometry: Theory, Computation and Applications

Seismic interferometry extracts information from the ambient seismic field and enables imaging in the absence of earthquakes or artificial sources. Recent developments in seismic interferometry have benefited from continuous records of ambient seismic noise from traditional broadband instruments and emerging new acquisition technologies, such as large-N nodal arrays and distributed acoustic sensing systems. These have opened up the possibility of performing high-resolution tomographic imaging anywhere dense networks are available. In addition, the temporal variation in continuous seismic records provides the possibility of monitoring the transient changes of subsurface properties for various geological targets, such as glaciers, volcanoes, groundwater, reservoirs, active faults, infrastructure and even other planetary bodies. We welcome contributions of recent advances in and applications of seismic interferometry on a broad range of topics, including (but not limited to) theoretical developments in amplitude measurements and structural inversion, utilization of higher-order cross-correlations, new analyzing techniques and computer programs and novel applications across disciplines.
