The cross correlation of ambient signal allows seismologists to collect data even in the
absence of seismic events.“Seismic interferometry” shows that the cross correlation of …

Seismic attenuation and the associated quality factor (Q) have long been studied in various
sub-disciplines of seismology, ranging from observational and engineering seismology to …

Although naturally occurring vibrations have proven useful to probe the subsurface, the
vibrations caused by traffic have not been explored much. Such data, however, are less …

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 …

We evaluate, by numerical tests, whether surface‐wave attenuation can be determined from
ambient‐noise data. We generate synthetic recordings of numerically simulated ambient …

The ambient noise correlation function (NCF) calculated between seismic stations contains,
under appropriate conditions, accurate travel time information. However, NCF amplitudes …

This dissertation deals with the in situ characterization of the small-strain shearwave velocity
and dam** ratio from the interpretation of Multi-channel Analysis of Surface Waves …

Infrasound recordings can be used as input to inversion procedures to delineate the vertical
structure of temperature and wind in a range of altitudes where ground-based or satellite …

SUMMARY A wide spectrum of processing schemes is commonly applied during the
calculation of seismic noise correlations. This is intended to suppress large-amplitude …

High-speed train (HST) generates strong and repeatable vibrations that could be used for
subsurface imaging and monitoring. Compared with other ambient noise, HST vibrations are …
