Passive Seismic Marchenko Imaging
2020<p>In recent years, seismic interferometry (SI) has been widely used in passive seismic data, it allows to retrieve new seismic responses among physical receivers by cross-correlation or multidimensional deconvolution (MDD). Retrieval of reflected body waves from passive seismic data has been proved to be feasible.

Passive Pressure During Seismic Loading
Journal of Geotechnical Engineering, 1986The results of a parametric study (based on a Mononobe-Okabe analysis) of passive earth pressure resistance of cohesionless soils under dynamic loading are presented. Since passive resistance decreases with increasing ground acceleration while the failure zone increases in size, retaining structures designed for static loading conditions may prove to ...

A method for passive location of seismic sources
Geoexploration, 1982Abstract This paper discusses a methodology useful in locating sources of influence in a medium, whether they are considered to be “signals” or “noises”. It also presents results of measurement of the coherence, across a geophone array, of seismic signals generated by a moving six-ton truck. The phase fronts of waves emanating from a source through a

Seismic interferometry for passive and exploration data
Proceedings of the 8th SEGJ International Symposium, 2006Exact Green’s function representations for seismic interferometry are based on the assumption that the receivers used in the correlation process are surrounded by a closed surface of sources. We investigate two situations for which this condition is not fulfilled: sources only in the subsurface, as in passive seismics, and sources only at the surface ...

Wavefront Tomography for Passive Seismic Data
Second EAGE/PESGB Workshop on Velocities, 2019Summary We propose a workflow for velocity model building based on passive seismic data. The under-lying tomographic inversion makes use of the slopes and curvatures of the recorded wavefield and inverts for velocities, source locations and source excitation times simultaneously.

Frontier Exploration Using Passive Seismic
First EAGE Passive Seismic Workshop - Exploration and Monitoring Applications, 2006We present a case history of 3-D seismic imaging in the Uinta Basin of Utah using passive seismic as an example of how passive techniques can aid exploration efforts in frontier areas. The area is topographically rugged making conventional seismic exploration expensive.

New Frontiers in Passive Seismic Monitoring
19th Congress of the Brazilian Geophysical Society - ProceedingsPassive seismic monitoring is a critical component in managing subsurface operations using seismicity as a feedback mechanism to guide operational decisions. These applications typically focus on locating events, estimating magnitudes, and characterizing ground motion to manage induced seismicity risks. In this talk, we explore advanced uses of passive

Imaging the earth with passive seismic arrays
The Leading Edge, 2003Earthquake and exploration seismology share a common foundation in elastic wave propagation. Most of what we know about earthquakes is known from the elastic waves they emit, while seismic methods in exploration are all about using scattered elastic waves to image earth structure. Seismologists have been using elastic waves to probe the earth since the
