We present the first-generation global tomographic model constructed based on adjoint
tomography, an iterative full-waveform inversion technique. Synthetic seismograms were …

Full waveform inversion (FWI) is a high-resolution seismic imaging technique that is based
on using the entire content of seismic traces for extracting physical parameters of the …

We have successfully applied full‐3‐D tomography (F3DT) based on a combination of the
scattering‐integral method (SI‐F3DT) and the adjoint‐wavefield method (AW‐F3DT) to …

Seismograms are convolution results between seismic sources and the media that seismic
waves propagate through, and, therefore, the primary observations for studying seismic …

We demonstrate the feasibility of high-resolution seismic array imaging based on
teleseismic recordings using full numerical wave simulations. We develop a hybrid method …

We used 3D spectral‐element seismic wave simulations and data from 112 earthquakes
and 1,311 seismic stations, totalizing 20,884 unique ray paths, to construct an adjoint …

Seismic tomography, when calibrated with borehole data, can be a highly effective tool for
investigating the deep structure of the critical zone. In this study, we have successfully …

Due to increased computational capabilities afforded by modern and future computer
architectures, the seismology community is demanding a more comprehensive …

Scientific computation has, for decades, helped us understand and quantify the processes
that shape Earth, including convection in the Earth's core and mantle, plate tectonics, and …

In the past few years, En-Jui and I have been working on a new Community Velocity Model
(CVM) for Southern California by iteratively improving CVM-S4 through both the SI and the …
