Infrasound From Large Earthquakes Recorded on a Network of Balloons in the Stratosphere

Geophysical Research Letters, 2022
The ground movements induced by seismic waves create acoustic waves propagating upward in the atmosphere, thus providing a practical solution to perform remote sensing of planetary interiors.

On Seismic Waves (Second Paper) [PDF]

, 1935
In a first paper under the present title the authors have presented a body of data on travel times. The present paper contains the corresponding data on amplitudes, periods, velocities, etc., for bodily waves.

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]

, 2020
We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

Seismic analysis of underground tunnels subjected to 3D oblique incident P and SV waves by 2.5D approach

Underground Space, 2023
This paper presents, for the first time, the consideration of three-dimensional (3D) oblique incident P and SV waves in calculating the 3D seismic response of a lined tunnel embedded in a half-space by the 2.5D finite/infinite element method (FIEM ...

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]

, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

A multiphase seismic investigation of the shallow subduction zone, southern North Island, New Zealand [PDF]

, 2001
The shallow structure of the Hikurangi margin, in particular the interface between the Australian Plate and the subducting Pacific Plate, is investigated using the traveltimes of direct and converted seismic phases from local earthquakes.

Seismic response analysis of subway station under obliquely incident SV waves

Scientific Reports
This paper aims to investigate the dynamic response characteristics of subway station under earthquakes. To this end, seismic waves are transformed into equivalent nodal loads on viscoelastic artificial boundaries using theories and methods of wave ...

Subsonic near-surface P-velocity and low S-velocity observations using propagator inversion [PDF]

, 2005
Detailed knowledge of near-surface P- and S-wave velocities is important for processing and interpreting multicomponent land seismic data because (1) the entire wavefield passes through and is influenced by the near-surface soil conditions, (2) both ...

Machine learning for gravitational-wave detection: surrogate Wiener filtering for the prediction and optimized cancellation of Newtonian noise at Virgo

, 2020
The cancellation of noise from terrestrial gravity fluctuations, also known as Newtonian noise (NN), in gravitational-wave detectors is a formidable challenge. Gravity fluctuations result from density perturbations associated with environmental fields, e.
