Seismic velocity structure in the Earth’s outer core
[1] We constrain seismic velocity structure in the Earth’s outer core by analyzing differential travel times, waveforms, and amplitude ratios of several pairs of core phases. We use differential travel times and waveforms of PKPbc-PKIKP at 144 –148 , PKiKP-PKIKP at 120 –141 , PKiKP-PKPBdiff at the PKP caustics distance range (141 –145 ), and differential travel times and amplitude ratios of PKP...
متن کاملRelationship between head wave amplitudes and seismic refraction velocities to detect lateral variation in the refractor
Refractor ambiguities are big problem in seismic refraction method especially in seismic engineering. There can be hidden subsurface geological phenomena such as hidden faults and shear zones which are not simply predicted by the travel-time graph or some geophysical methods. Head wave amplitudes are used to show the resolution of refractor ambiguities and the existence of anisotropy in complex...
متن کاملShort Note Seismic Anisotropy from SKS Splitting beneath Northeastern Tibet
The northeastern boundary of the Tibetan high plateau is marked by a 2 km topographic drop and a coincident rapid change in crustal thickness. Surface tectonics are dominated by the Kunlun strike-slip fault system and adjacent Kunlun concealed thrust. The main objective of the current study is to map lateral variations of seismic anisotropy parameters in this region along the linear INDEPTH IV ...
متن کاملSeismic Velocity Estimation from Time Migration Velocities
We address the problem of estimating seismic velocities inside the earth which is necessary for obtaining seismic images in regular Cartesian coordinates. We derive a relation between the true seismic velocities and the routinely obtained so called ”time migration velocities”, which are some kind of mean velocities. We formulate an inverse problem and show that it is ill-posed. We suggest three...
متن کاملSeismic anisotropy and slab dynamics from SKS splitting recorded in Colombia
The Nazca, Caribbean, and South America plates meet in northwestern South America where the northern end of the Andean volcanic arc and Wadati-Benioff zone seismicity indicate ongoing subduction. However, the termination of Quaternary volcanism at ~5.5°N and eastward offset in seismicity underneath Colombia suggest the presence of complex slab geometry. To help link geometry to dynamics, we ana...
