Seismic receiver function interpretation:Ps splitting or anisotropic underplating?

Crustal structure and apparent tectonic underplating from receiver function analysis in South Island, New Zealand

[1] We utilize seismic converted phases on more than 700 receiver functions calculated for 42 stations in the South Island, New Zealand, to infer crustal and uppermost mantle structure. We determine the crustal thickness from direct observations of conversion from the Moho interface and infer zone of the maximum thickness being located along the axis of the Southern Alps, just east from the Alp...

Seismic Gradiometry using Ambient Seismic Noise in an Anisotropic Earth

seismic study of upper mantle beneath the nw iran using p receiver function

rf method is now a well-known tool for studying crustal and upper mantle structure when such a complete data set is available. we compute p receiver functions to investigate the upper mantle discontinuity beneath the northwest of iran. we selected data from teleseismic events (mb ? 5.5, 30 ?>? > 95?) recorded from 1995 to 2008 at 8 three component short period stations from tabriz telemetry sei...

Consistent Positive Directional Splitting of Anisotropic Diffusion

Anisotropic nonlinear diffusion filters describe a large class of powerful image filtering operations. In order to be applicable to sampled data, the continuous diffusion equations have to be discretized, e.g. using additive operator splitting scheme which approximates the continuous equation by one-dimensional processes along several chosen directions. In this paper we concentrate on one step ...

Estimating crustal seismic anisotropy with a joint analysis of radial and transverse receiver function data

S U M M A R Y We developed an integrated technique for estimating crustal anisotropy with a horizontal axis using radial (R) and transverse (T) receiver functions. The technique includes computing three individual and one joint objective function (JOF) and a reliability analysis of the estimated anisotropy. The individual objective functions (IOFs) are designed to: (1) maximize the peak energy ...
