Abstract Since 1.25 Ma, three volcanic systems in the western US Cordillera hosted rhyolitic
eruptions of≳ 300 km 3 dense rock equivalent creating the Yellowstone (0.63 Ma), Long …

We apply the double‐beamforming tomography to a monthlong temporary dense seismic
array to obtain high‐resolution images of the San Jacinto Fault's damage zone. We obtain …

Elastic properties of near-surface materials and their effects on seismic wave propagation
are of fundamental interest in groundwater, engineering, and environmental studies. Shear …

Ambient wavefield data acquired on existing (so-called 'dark fibre') optical fibre networks
using distributed acoustic sensing (DAS) interrogators allow users to conduct a wide range …

In this study we recast surface wave traveltime tomography as an inverse problem
constrained by an eikonal equation and solve it using the efficient adjoint‐state method …

Monitoring time‐lapse changes in subsurface physical properties of the near‐surface critical
zone is increasingly important with respect to climate change, environmental conservation …

Ambient noise tomography (ANT) is a widely used method to obtain shear wave velocity
structure in the crust and upper mantle. Usually, the topography is assumed to have …

We present a dispersion‐inversion method which inverts for the P‐velocity model from
guided waves propagating in wave guides of arbitrary geometry. Its misfit function is the …

Distributed acoustic sensing (DAS) is a new dense sampling seismic observation technique
rapidly developed to image near‐surface velocity structures. Compared with traditional …

Logistic regression, neural networks and support vector machines are tested for their
effectiveness in isolating surface waves in seismic shot records. To distinguish surface …
