Characterization and ‘Source-Receiver’ Continuation of Seismic Reflection Data
In reflection seismology one places sources and receivers on the Earth’s surface. The source generates elastic waves in the subsurface, that are reflected where the medium properties, stiffness and density, vary discontinuously. In the field, often, there are obstructions to collect seismic data for all source-receiver pairs desirable or needed for data processing and application of inverse sca...
متن کاملPitfalls in Shallow Seismic Reflection
Substantial progress has occurred during the past 15 years in development of shallow CDP seismic-reflection techniques, but there are occasional interpretation problems with the resulting data. We discuss examples of the pitfalls of the method, along with some procedures to help avoid them. Problems that often occur include spatial aliasing of ground roll, interpreting processed ground-coupled ...
متن کاملEstimating 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 ...
متن کاملseismic 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...
متن کاملGreen's function retrieval from reflection data, in absence of a receiver at the virtual source position.
The methodology of Green's function retrieval by cross-correlation has led to many interesting applications for passive and controlled-source acoustic measurements. In all applications, a virtual source is created at the position of a receiver. Here a method is discussed for Green's function retrieval from controlled-source reflection data, which circumvents the requirement of having an actual ...
