Detection of Weak Seismic Signals in Noisy Environments from Unfiltered, Continuous Passive Seismic Recordings

Extracting Seismic Profiles from Background Seismic Signals

The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...

Detection 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...

Deconvolution Tools for Seismic Signals

This note provides complete details of the numerical algorithm implemented in the software package for signal resortoration of seismic signals [5]. The complete software package is available electronically [6].

Efficient Computation of Passive Seismic Interferometry

SUMMARY Seismic interferometry is from a computationally point of view based on cross-correlating two signals. One application of seismic interferometry lies in passive seismics. In passive seismic recorders are placed on the surface of the earth and signals are continuously measured. In this abstract we investigated an efficient way of computing the cross-correlation, of a limited number of ou...
