With the emergence of portable broadband seismic instrumentation, availability of digital
networks with wide dynamic range, and development of new powerful analysis techniques …

Monitoring landslides is essential to understand their dynamics and to reduce the risk of
human losses by raising warnings before a failure. A decade ago, a decrease of apparent …

Historic levels of drought, globally, call for sustainable freshwater management. Under
pressing demand is a refined understanding of the structures and dynamics of groundwater …

The term seismic interferometry refers to the principle of generating new seismic responses
by crosscorrelating seismic observations at different receiver locations. The first version of …

[1] We propose passive image interferometry as a technique for seismology that allows to
continuously monitor small temporal changes of seismic velocities in the subsurface. The …

Coda waves are sensitive to changes in the subsurface because the strong scattering that
generates these waves causes them to repeatedly sample a limited region of space. Coda …

Aquifers are vital groundwater reservoirs for residential, agricultural, and industrial activities
worldwide. Tracking their state with high temporal and spatial resolution is critical for water …

To monitor both the permanent (thermal microcracking) and the nonpermanent (thermo‐
elastic) effects of temperature on Westerly Granite, we combine acoustic emission …

In the 1990s, the method of time-reversed acoustics was developed. This method exploits
the fact that the acoustic wave equation for a lossless medium is invariant for time reversal …

This paper proposes a new concept, named the Detectable Resolution of Bolt Pre-load
(DRBP), by using the coda wave interferometry (CWI) to quantitatively measure the pre-load …
