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

The spatial distribution of temporal variations in seismic wavespeed is key to understanding
the sources and physical mechanisms of various geophysical processes. The imaging of …

Surface wave imaging based on the normal modes extracted via ambient noise cross‐
correlation has become a popular seismological technique during the last two decades. In …

Vehicle‐induced seismic waves, generated as vehicles traverse the ground surface, carry
valuable information for imaging the underlying near‐surface structure. These waves …

Seismologists are eagerly seeking new and preferably low‐cost ways to map and track
changes in the complex structure of the top few kilometers of the crust. By understanding it …

Temporal changes in subsurface properties, such as seismic wave speeds, can be
monitored by measuring phase shifts in the coda of two seismic waveforms that share a …

We develop a new method to monitor and locate seismic velocity changes in the subsurface
using seismic noise interferometry. Contrary to most ambient noise monitoring techniques …

Water‐resource management has become a major global issue in a world threatened by
climate change. High‐resolution geophysical methods may be of valuable help in …

Train traffic has been recognized as a powerful noise source for subsurface imaging and
monitoring due to its properties of being strong, economic and repeatable. Compared with …

The ambient seismic field is now routinely used for imaging and monitoring purposes. Most
commonly, applications aim at resolving crustal‐scale features and utilize ocean‐generated …
