Locate Microseismicity by Seismic Interferometry

Proceedings, 2009
We present a new seismic interferometry method to locate microseismicity by crosscorrelating the direct P- and S-waves from repeating sources, e.g., hydro-fracture. Typically microseismic data by surface array are below signal-to-noise ratio for a migration-type approach, and barely pickable for a traveltime-base approach.

Imaging the Subsurface Plumbing Complex of Steamboat Geyser and Cistern Spring With Hydrothermal Tremor Migration Using Seismic Interferometry

Journal of Geophysical Research: Solid Earth, 2020
Steamboat Geyser in Yellowstone National Park is the tallest active geyser on Earth and is believed to have hydrologic connection to Cistern Spring, a hydrothermal pool ∼100 m southwest from the geyser vent.

Seismic interferometry by cross‐correlation or deconvolution?

SEG Technical Program Expanded Abstracts 2008, 2008
We discuss Rodney Calvert's work on the Virtual Source method in the context of seismic interferometry. Moreover, we present a systematic analysis of seismic interferometry by cross-correlation versus multi-dimensional deconvolution and we discuss applications of both approaches.

Full structural dynamic response from ambient vibration of Giotto's bell tower in Firenze (Italy), using modal analysis and seismic interferometry

NDT & E international, 2019
The preservation of historical buildings mainly depends on our capacity to monitor their ageing and quickly detect potential damage. We show how the dynamic characteristics of a building (i.e., frequency, shapes mode and seismic wave velocity) can be ...

5. Seismic Interferometry

2014
Controlled-source interferometry and ambient-noise interferometry are becoming important tools in earth science. Ambient-noise interferometry is already one of the most important methods for obtaining high-resolution imaging of the crust and upper mantle from dense continent-sized arrays.

Applications of seismic interferometry to seismic field data

The Journal of the Acoustical Society of America, 2007
In seismic interferometry one extracts the Green’s function of a system from fluctuations in the system. This makes it possible to retrieve the waves that propagate between receivers, as if one of the receivers acts as a source. Examples are presented of this principle to field data.

Effect of Intrinsic Losses on Seismic Interferometry

70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008
Seismic interferometry (SI) is the process of generating new seismic traces from the cross-correlation of existing traces. One of the starting assumptions for deriving the SI representation equations is that of a lossless medium. In practice, this condition is not always met.

Seismic Interferometry

2009
Seismic interferometry is an exciting field in geophysics utilising multiple scattering events to provide unprecedented views of the Earth's subsurface. This is a comprehensive book describing the theory and practice of seismic interferometry with an emphasis on applications in exploration seismology.

Seismic Interferometry in Near-Surface Seismics - An Experiment

Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics, 2006
Seismic interferometry (SI) is the process of generating new seismic records from the cross-correlation of existing records. The interest to SI is growing, but mainly in hydrocarbon exploration and global seismology. The application of SI to shallow seismics could help to extract more information form the data and at the same time save efforts and time

Seismic Interferometry Applied to Seismic Background-Noise Field Data

Proceedings of the 8th SEGJ International Symposium, 2006
One of the applications of Seismic Interferometry (SI) is the reconstruction of the Earth’s reflection response from the crosscorrelation of seismic background noise recorded at the surface. In recent years, several authors have derived the relations that govern this process.
