Resolving rupture processes of great earthquakes has fundamental importance to the study
of earthquake physics, rupture dynamics, fault zone structure, and evolving processes. It …

Full waveform tomography is an effective method to obtain high‐resolution subsurface
velocity structures. It is, however, difficult for the conventional L2‐norm‐based inversion to …

The wave-induced fluid flow (WIFF) is considered to be the main cause of dispersion and
attenuation of seismic waves in fluid-saturated porous media. Among numerous theories …

In this paper, we present a dispersion–dissipation analysis of the triangle-based
discontinuous Galerkin method (DGM) for scalar wave equation. The DGM is based on the …

Seismic tomography is one of the main tools to explore the interior of the earth. In this study,
the quasi-waveform seismic tomographic method is used for the first time to reveal the …

Reverse time migration (RTM) is widely used in the industry because of its ability to handle
complex geologic models including steeply dipping interfaces. The quality of images …

Full waveform inversion (FWI) to estimate physical properties of a system is one of the major
research topics in science and engineering. This study proposes a probabilistic approach …

Joint inversion, such as the combination of receiver function and surface wave dispersion,
can significantly improve subsurface imaging by exploiting their complementary sensitivities …

Elastic full waveform inversion (EFWI) is essential for obtaining high-resolution multi-
parameter models. However, the conventional EFWI may suffer from severe cycle skipping …

The quadratic Wasserstein metric has shown its power in measuring the difference between
probability densities, which benefits optimization objective function with better convexity and …
