Upper mantle deformation beneath the North American–Pacific plate boundary in California from SKS splitting
[1] In order to constrain the vertical and lateral extent of deformation and the interactions between lithosphere and asthenosphere in a context of a transpressional plate boundary, we performed teleseismic shear wave splitting measurements for 65 permanent and temporary broadband stations in central California. We present evidence for the presence of two anisotropic domains: (1) one with clear...

متن کاملReceiver functions from regional P waves
P waves from regional-distance earthquakes are complex and reverberatory, as would be expected from a combination of head waves, post-critical crustal reflections and shallow-incident P waves from the upper mantle. Although designed for steeply-incident teleseismic P waves, receiver functions (RFs) can also retrieve information about crustal structure from regional P. Using a new computation me...
متن کاملthe lithosphere-asthenosphere boundary in the north-west of iran from s receiver function
recently, the s receiver function method has been successfully developed to identify upper mantle interfaces. s receiver functions have the advantage of being free of s-wave multiple reflections and can be more suitable than p receiver function for studying mantle lithosphere. however, because of specific ray geometry of the s-to-p converted waves, the s receiver function method has some techni...
متن کاملDetection of seismic discontinuities
In seismic images, the opaque oscillatory nature of the ever present sedimentary layers often hide the boundaries between sedimentary packages, such as faults or river channels. Interpreters painstakingly identify these boundaries by inspecting individual planes of the image volume. Discontinuity attribute maps computed from image volumes depict these boundaries and greatly simplify and acceler...
