Abstract When using waveform tomography to perform high-resolution imaging of a medium, it is vital to calculate the sensitivity in order to describe how well a model fits a given set of data and how the sensitivity changes with the spatial distribut

Seismic interferometry (SI) has been recently employed to retrieve the reflection response from natural earthquakes. We perform experimental study to apply SI to Ocean Bottom Seismogram (OBS) records in the Nankai Trough, southwest Japan in order to

Summary Time-lapse seismics has a wide range of application in different scales, from near-surface to resource exploration. Crosshole sesmics is used to characterize fluid reservoirs and to obtain highly resolved rock/soil-dynamic parameters e.g., el

When using scattered waves for high-resolution imaging of a medium, the sensitivity of these waves to the spatiotemporal distribution of heterogeneities is undoubtedly a key factor. The traditional principle behind using scattered waves to detect sma

Summary The porosity of the shallow soil layers is a crucial information in hydrogeology, soil science, agriculture, and construction engineering. To resolve the spatial distribution of porosity in soil, 3D elastic full waveform inversion (FWI) can b

To quantitatively image fractures with high resolution, we have developed an elastic least-squares migration (LSM) algorithm coupled with linear-slip theory, which accurately addresses seismic wave interaction with thin structures. We derive a linear

The elastic compliance of a fracture can be spatially varying, reflecting the variation of microscale properties of the fracture, e.g., aperture, contact asperities, and fracture infill. Characterizing the spatial heterogeneity of a fracture is cruci
