Premonitory Variations in S-Wave Velocity Anisotropy before Earthquakes in Nevada.
نویسنده
چکیده
Application of nonhydrostatic stress to rock induces velocity anisotropy, causing the S wave to split into two components traveling with somewhat different velocities. Large premonitory changes in the extent of S-wave splitting have been observed for two earthquakes in Nevada. Observations of the difference between the two S-wave velocities may provide a simple method for pedicting earthquakes.

Velocity variations in the uppermost mantle beneath the southern Sierra Nevada and Walker Lane
[1] We model Pn waveforms from two earthquakes in the southwestern United States (Mammoth Lakes, California, and western Nevada) to determine a velocity model of the crustal and mantle structure beneath the southern Sierra Nevada and Walker Lane. We derive a one-dimensional velocity model that includes a smooth crust-mantle transition east of Death Valley and extending south into the eastern Mo...
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 کاملP Wave Velocity Variations in the Coso Region, California, Derived From Local Earthquake Travel Times
Inversion of 4036 P wave travel time residuals from 429 local earthquakes using a tomographic scheme provides information about three-dimensional upper crustal velocity variations in the Indian Wells Valley-Coso region of southeastern California. The residuals are calculated relative to a Coso-specific velocity model, corrected for station elevation, weighted, and back-projected along their ray...
متن کاملSlab segmentation revealed by anisotropic P-wave tomography
[1] Seismic anisotropy is a useful indicator for identifying the physical and chemical condition of the Earth’s interior, such as stress and flow fields, and in situ constituent minerals. Using traveltime tomography, we examined threedimensional anisotropic P-wave velocity structure of the Kii Peninsula, southwest Japan, where source regions of megathrust earthquakes along the Nankai Trough are...
متن کاملTorsional Surface Wave Propagation in Anisotropic Layer Sandwiched Between Heterogeneous Half-Space
The present paper studies the possibility of propagation of torsional surface waves in an inhomogeneous anisotropic layer lying between two heterogeneous half-spaces (upper and lower half-space). Both the half-spaces are assumed to be under compressive initial stress. The study reveals that under the assumed conditions, a torsional surface wave propagates in the medium. The dispersion relation ...
