The structure of the lithosphere of the Black Sea by the results of 3D gravity analysis and seismic tomography

open access: yesГеофизический журнал, 2012
3D gravity analysis and local seismic tomography have been performed to study the lithosphere structure of the Black Sea. Due to gravity analysis gravity effects of different layers and levels of the model (sea water, four layers in sediments ...

Validating tomographic model with broad-band waveform modelling: an example from the LA RISTRA transect in the southwestern United States [PDF]

open access: yes, 2007
Traveltime tomographic models of the LA RISTRA transect produce excellent waveform fits if we amplify the damped images. We observe systematic waveform distortions across the western edge of the Great Plains from South American events, starting about 300

Seismological expression of the iron spin crossover in ferropericlase in the Earth’s lower mantle

open access: yesNature Communications, 2021
This study identifies the predicted seismic expression of the high-to-low iron spin crossover in the deep Earth mineral ferropericlase. A depth-dependent signal is detected in the fastest and slowest regions, related to lateral temperature variations, of

Juan de Fuca subduction zone from a mixture of tomography and waveform modeling [PDF]

open access: yes, 2012
Seismic tomography images of the upper mantle structures beneath the Pacific Northwestern United States display a maze of high-velocity anomalies, many of which produce distorted waveforms evident in the USArray observations indicative of the Juan de ...
