Imaging the Earth Across Scales with Correlation Wavefield
Presented by Erdinc Saygin
Much of the effort over the past decade in the field of passive seismic imaging has focused on using seismic ambient noise signals recorded simultaneously by seismic sensor networks, mainly utilizing the surface wave component of the wavefield in seismic imaging. Meanwhile, some of the recent methodological developments enabled the use of body waves of the seismic correlation wavefield in earth imaging retrieved from the ambient seismic noise signals and also the scattered part of the earthquake signals.
I present some of the new developments in the utilization of the surface and body waves of the seismic correlation wavefield in structural imaging and monitoring in 4D with examples around the world. I also introduce a new interferometric wavefield reconstruction technique for improving the accuracy and volume of the measurements in earth imaging.
