    A new method for determining lower density layer in prospection of hydrocarbon by Ali ELMAS, Hasan ÇAVŞAK

    Published 2016-06-01
    “…However, density is an irregular variable that depends on the change boundaries of seismic velocity. In this study, it is aimed to take density into account as a variable by using detected seismic velocity boundaries at which seismic velocity changes for each formation. …”

    Probing environmental and tectonic changes underneath Mexico City with the urban seismic field by L. A. Ermert, L. A. Ermert, E. Cabral-Cano, E. Chaussard, D. Solano-Rojas, L. Quintanar, D. Morales Padilla, E. A. Fernández-Torres, M. A. Denolle

    Published 2023-05-01
    “…We used autocorrelations of urban seismic noise, enhanced by waveform clustering, to extract subtle seismic velocity changes by coda wave interferometry. We observed and modeled seasonal, co- and post-seismic changes, as well as a long-term linear trend in seismic velocity. …”

    Topography of the 410-km discontinuity from PP and SS precursors by Chambers, K, Woodhouse, J, Deuss, A

    Published 2005
    “…In smaller regions beneath Northeast Asia and the Western Pacific we observe positive correlations between seismic velocities and discontinuity topography, which we interpret as evidence for the effects of chemical heterogeneities on seismic velocities and the 410-km discontinuity. …”

    Large-scale structures in the Earth’s interior: Top-down hemispherical dynamics constrained by geochemical and geophysical approaches by Hikaru Iwamori, Masaki Yoshida, Hitomi Nakamura

    Published 2022-12-01
    “…Seismic velocity structure is the major source of information on the Earth’s interior and provides the best spatial resolution, while electrical conductivity is sensitive to water/hydrogen contents. …”

    Space-time monitoring of groundwater fluctuations with passive seismic interferometry by Mao, Shujuan, Lecointre, Albanne, van der Hilst, Robert D, Campillo, Michel

    Published 2023
    “…Employing advanced seismic interferometry techniques, we calculate the space-time evolution of relative changes in seismic velocity, as a measure of hydrological properties. …”

    The inversion of reflected waves for Moho discontinuity along the Hayward Fault, California by Liu, Jiabei

    Published 2020
    “…With the base of the single-layered initial model, a general seismic velocity structure can be extended by adding the complex seismic velocity discontinuities gradually. …”

    Continental residual topography extracted from global analysis of crustal structure by Stephenson, SN, Hoggard, MJ, Holdt, MC, White, N

    Published 2024
    “…In order to convert crustal seismic velocity into density, we develop a parametrization that is based upon a database of 1,136 laboratory measurements of seismic velocity as a function of density and pressure. …”
