Three-dimensional P-wave velocity structure beneath the Indonesian region

Tectonophysics, 1993
Abstract We present the P-wave seismic tomography image of the mantle to a depth of 1200 km beneath the Indonesian region. The artb inversion method is applied to a dataset of 118,203 P-wave travel times of local and teleseismic events taken from ISC bulletins.

Three-dimensional velocity structure and seismicity of Mt. Etna Volcano, Italy

Journal of Volcanology and Geothermal Research, 1997
Abstract A new set of three-dimensional velocity models beneath Mt. Etna volcano is derived in the present work. We have used P- and S-wave arrivals from local earthquakes recorded at permanent and temporary seismic networks installed since 1980.

Three-dimensional shallow velocity structure beneath Taal Volcano, Philippines

Journal of Seismology, 2017
Based on its numerous historical explosive eruptions and high potential hazards to nearby population of millions, Taal Volcano is one of the most dangerous “Decade Volcanoes” in the world. To provide better investigation on local seismicity and seismic structure beneath Taal Volcano, we deployed a temporary seismic network consisting of eight stations ...

Three-dimensional velocity structure and tectonic characteristics of earthquake area in Yibin

Applied Geophysics, 2019
In this study, on the basis of absolute first-arrival times of 84756 P- and S-waves from 6085 earthquakes recorded at 56 fixed stations in Yibin and surrounding areas in China from January 2009 to January 2019, focal parameters and three-dimensional (3D) body-wave high-resolution velocity structures at depths of 0–30 km were retrieved by double ...

Three-Dimensional Structure of Pressure–Velocity Correlations in a Turbulent Boundary Layer

2015
Three-dimensional pressure–velocity correlations in a turbulent boundary layer have been investigated to understand the relationship between the pressure fluctuations and the coherent structures. Simultaneous measurements of the fluctuating pressure and velocity fields have been performed by the point pressure measurement technique and stereo PIV.

Three‐dimensional elastic wave velocity structure of the western and central Tien Shan

Journal of Geophysical Research: Solid Earth, 1993
Arrival times of compressional (P) and shear (S) waves generated by earthquakes at local and teleseismic distances and recorded by seismographs located in the western and central Tien Shan are used to determine one‐ and three‐dimensional elastic wave velocity structures of the crust and upper mantle beneath the mountain belt.

Modelling the three dimensional structure of velocity storage in the vestibulo-ocular reflex (VOR)

Proceedings of the 1988 Fourteenth Annual Northeast Bioengineering Conference, 2003
It is shown that velocity storage can be generalized to three dimensions to explain the cross-coupling from horizontal slow phase velocity to vertical and roll eye velocity. The key conclusion is that the eigenvalues and the orientation of the eigenvectors of the system matrix associated with the velocity storage integrator are closely linked to the ...

Three-Dimensional Velocity Structure and Suspended Sediments at Coral Reefs in Teluk Banten, Indonesia

Coastal Engineering 2000, 2001
Suspended sediment dynamics at two fringing coral reef islands in Teluk Banten, Indonesia, were investigated during wet season. Both islands are surrounded by waters of approximately 8 m depth and have a width of 600 m, whereas one is located close to a former delta platform and fully exposed to waves from the Java Sea, and the other is situated in a ...

Three-Dimensional Seismic Velocity Structure of the Earth's Outermost Core and Mantle

1995
Obtaining an accurate, detailed picture of deep-Earth structure is of fundamental importance in a wide range of geophysical applications such as fluid dynamic, magnetohydrodynamic, and mineral physics models of the Earth which incorporate properties determined from seismology. Because it is such a drastic chemical and thermal boundary layer, the nature
