Over the past two decades, the development of the ambient noise cross‐correlation
technology has spawned the exploration of underground structures. In addition, ambient …

Noise‐based crustal seismic velocity changes are known to be affected by environmental
perturbations, such as rainfall, atmospheric pressure loading, and temperature changes …

Measuring stress changes within seismically active fault zones has been a long-sought goal
of seismology. One approach is to exploit the stress dependence of seismic wave velocity …

Continuous monitoring of in situ reservoir responses to stress transients provides insights
into the evolution of geothermal reservoirs. By exploiting the stress dependence of seismic …

Monitoring the stress state and its change of underground media can promote the
knowledge and understanding of the physical process that causes earthquakes. Seismic …

We observe seasonal seismic wave speed changes (dv/v) in the San Jacinto fault area and
investigate several likely source mechanisms. Velocity variations are obtained from analysis …

Volcanic inflation and deflation often precede eruptions and can lead to seismic velocity
changes () in the subsurface. Recently, interferometry on the coda of ambient noise‐cross …

Seismic noise interferometry is an exciting technique for studying volcanoes, providing a
continuous measurement of seismic velocity changes (dv/v), which are sensitive to …

Our study investigates variations of seismic velocity that occur over short time scales of
hours. We use coda wave interferometry to inspect 5 months of continuous data from a …

Continuous crosswell seismic monitoring of a small-scale CO 2 injection was accomplished
with the development of a novel tubing-deployed piezoelectric borehole source. This …
