When Sue Hough asked me to review this new textbook I accepted immediately. I've been watching it mature for almost two decades and am pleased it is now actually published as a real textbook. I first became aware of a much earlier draft when I began teaching and was tasked to teach an introductory seismology course for new graduate students. At that time (early 1980's) there was a major gap in ...

We revisit the problem of recovering wave speeds and density across a curved interface from reflected amplitudes. Such amplitudes have been exploited for decades in (exploration) seismology this context. However, analysis has based on linearization mostly flat interfaces. Here, we present an without allow interfaces, establish uniqueness provide reconstruction, while making notion amplitude pre...

Pulsation modes have recently been observed in a handful of white dwarf (WD) primaries of cataclysmic variables, allowing an interesting new probe into the structure of accreting WD's. We briefly discuss the seismology of these objects, how stellar properties may be inferred from the observed mode frequencies, and mode driving mechanisms. For one pulsator, GW Lib, we have shown that a WD mass M...

We demonstrate for the first time that seismic resonant multiples, usually considered as noise, can be used for super-resolution imaging in the far-field region of sources and receivers. Tests with both synthetic data and field data show that resonant multiples can image reflector boundaries with resolutions more than twice the classical resolution limit. Resolution increases with the order of ...

The development of supervised deep learning technology in seismology and related fields has been restricted due to the lack training sets. A large amount unlabeled data is recorded seismic exploration, their application network difficult, e.g., fault identification. To solve this problem, herein, we propose an end-to-end set generative adversarial Fault2SeisGAN. This can expand limited labeled ...

The generalized finite-element method (GFEM) has been applied frequently to solve harmonic wave equations, but its use in the simulation of transient propagation is still limited. We have GFEM for acoustic equation models relevant exploration seismology. also perform an assessment accuracy and efficiency. main advantage that it provides enhanced solution compared standard (FEM). This attained b...

[1] Multivalued traveltimes have traditionally not been used in seismic imaging, with only a handful of notable exceptions in the field of exploration geophysics. For studies at local and regional scales (e.g., local earthquake/teleseismic tomography), the focus has largely been on first arrivals, with numerous rayand grid-based schemes developed for their calculation. However, later arrivals o...
