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 …

Passive surface wave methods have gained much attention from geophysical and civil
engineering communities because of the limited application of traditional seismic surveys in …

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 …

Waves generated by opportunistic or ambient noise sources and recorded by passive
sensor arrays can be used to image the medium through which they travel. Spectacular …

This paper introduces a technique for improving seismic noise correlation functions (NCF)
via a singular value decomposition (SVD) of a list of NCF and the Wiener filter. SVD is …

Train traffic has recently been realized as a potential seismic source for imaging and
monitoring shallow subsurface structures. High-speed trains usually move on viaducts and …

An areal distribution of sensors can be used for estimating the direction of incoming waves
through beamforming. Beamforming may be implemented as a phase-shifting and stacking …

In this study, we use ambient seismic noise recorded at selected broadband USArray
Earthscope Transportable Array (TA) stations to obtain effective reflection seismograms …

In the petroleum industry, advances in technology are required for cost-effective production
in key reservoir exploration areas and oil-well production management to increase yield and …

We present a way of characterizing the structure beneath a seismic station, by exploiting
stacked correlograms of three‐component records from teleseismic events. This seismic …
