Combined use of repeated active shots and ambient noise to detect temporal changes in seismic velocity: application to Sakurajima volcano, Japan

Coda-wave interferometry is a technique to detect small seismic velocity changes using phase changes in similar waveforms from repeating natural or artificial sources. Seismic interferometry is another technique for detecting seismic velocity changes from cross-correlation functions of ambient seismic noise. We simultaneously use these two techniques to clarify seismic velocity changes at Sakur...

Monitoring change in volcanic interiors using coda wave interferometry: Application to Arenal Volcano, Costa Rica

[1] Multiply scattered waves are a new tool for monitoring changes in the earth’s subsurface. In this study we use the air pressure and displacement recorded at the Arenal Volcano to detect temporal changes. The pressure pulses emitted by the volcano are associated with a complex displacement signal of overlapping coda waves. By deconvolving the ground motion with the air pressure for different...

Time-lapse monitoring of rock properties with coda wave interferometry

[1] The coda of seismic waves consists of that part of the signal after the directly arriving phases. In a finite medium, or in one that is strongly heterogeneous, the coda is dominated by waves which have repeatedly sampled the medium. Small changes in a medium which may have no detectable influence on the first arrivals are amplified by this repeated sampling and may thus be detectable in the...

Coda wave interferometry and the equilibration of energy in elastic media.

Multiple-scattered waves usually are not useful for creating deterministic images of the interior of elastic media. However, in many applications, one is not so much interested in making a deterministic image as in detecting changes in the medium. Cases in point are volcano monitoring and measuring the change in hydrocarbon reservoirs during enhanced recovery operations. Coda wave interferometr...
