Teleseismic P‐Wave Attenuation Beneath the Southeastern United States
Geochemistry, Geophysics, Geosystems, 2021 Seismic attenuation is an important parameter for characterizing subsurface morphology and thermal structure. In this study, we use P‐wave amplitude spectra from 588 teleseismic events recorded by 477 broadband seismic stations in the southeastern United

Accurately Stable Q-Compensated Reverse-Time Migration Scheme for Heterogeneous Viscoelastic Media
Remote Sensing, 2022 The development of multi-component seismic acquisition technology creates new possibilities for the high-precision imaging of complex media. Compared to the scalar acoustic wave equation, the elastic wave equation takes the information of P-waves, S ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Is there seismic attenuation in the mantle?
Earth and Planetary Science Letters, 2014 The small scale heterogeneity of the mantle is mostly due to the mixing of petrological heterogeneities by a smooth but chaotic convection and should consist in a laminated structure (marble cake) with a power spectrum S(k) varying as 1/k, where k is the wavenumber of the anomalies.

Frontiers in Earth Science, 2021 Frequency-dependent attenuation (1/Q) should be used as a seismic attribute to improve the accuracy of seismic methods and imaging of the subsurface. In rocks, 1/Q is highly sensitive to the presence of saturating fluids.

SEISMIC ATTENUATION FOR RESERVOIR CHARACTERIZATION [PDF]
, 2002 In Section 1 of this first report we will describe the work we are doing to collect and analyze rock physics data for the purpose of modeling seismic attenuation from other measurable quantities such as porosity, water saturation, clay content and net stress.
