Towards a first design of a Newtonian-noise cancellation system for Advanced LIGO [PDF]

, 2016
Newtonian gravitational noise from seismic fields is predicted to be a limiting noise source at low frequency for second generation gravitational-wave detectors. Mitigation of this noise will be achieved by Wiener filtering using arrays of seismometers deployed in the vicinity of all test masses.

Crowd-Funded Earthquake Early-Warning System [PDF]

arXiv, 2022
Earthquake early warning systems has been proven to save countless lives in Japan, Mexico, and Chile, where earthquake warnings are often broadcast live on TV up to a minute before residents experience shaking. Unfortunately, traditional early warning systems require extensive capital investment.

A Novel Approach of Wind Turbine Blade Root Load Monitoring Based on Bearings Vibrational Data and a New AE‐LSTM‐Attention Neural Network

Wind Energy, Volume 28, Issue 5, May 2025.
ABSTRACT The monitoring of wind turbine blade root load (BRL) has always been a valuable yet highly challenging problem. BRL monitoring is often measured directly using strain sensors, which are expensive to install and poses safety risks. Thus, it is necessary to explore an indirect measurement method that establishes a mapping relationship between ...

Diurnal expansion and contraction of englacial fracture networks revealed by seismic shear wave splitting

Communications Earth & Environment, 2021
Daily variations in seismic S-wave anisotropy reveal the dynamic response of englacial fractures to changing meltwater supply, according to shear wave splitting measurements from a seismometer network on the Rhonegletscher, Switzerland.

mFAST: A MATLAB toolbox for ocean bottom seismometer refraction first-arrival traveltime tomography

Earth and Planetary Physics, 2022
First-arrival seismic traveltime tomography (FAST) is a well-established technique to estimate subsurface velocity structures. Although several existing open-source packages are available for first-arrival traveltime tomography, most were written in ...

PickBlue: Seismic phase picking for ocean bottom seismometers with deep learning [PDF]

arXiv, 2023
Detecting phase arrivals and pinpointing the arrival times of seismic phases in seismograms is crucial for many seismological analysis workflows. For land station data machine learning methods have already found widespread adoption. However, deep learning approaches are not yet commonly applied to ocean bottom data due to a lack of appropriate training

Nostradamus: The radar that wanted to be a seismometer [PDF]

Geophysical Research Letters, 2010
Surface waves emitted after large earthquakes are known to induce, by dynamic coupling, atmospheric infrasonic waves propagating upward through the neutral and ionized atmosphere. Those waves have been detected in the past at ionospheric heights using a variety of techniques, such as HF Doppler sounding or GPS receivers.

Legacy Seismic and Gravity Data in the Vicinity of Great Meteor Seamount and Its Tectonic Implications

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract The Great Meteor seamounts are located in the eastern Atlantic Ocean, about 750 km south of the Azores. Conjugate to the Corner seamounts in the western Atlantic Ocean, it has been suggested they formed at the same hotspot that generated the New England Seamount chain.

Along‐Arc Heterogeneity in Local Seismicity across the Lesser Antilles Subduction Zone from a Dense Ocean‐Bottom Seismometer Network

Seismological Research Letters, 2019
The Lesser Antilles arc is only one of two subduction zones where slow‐spreading Atlantic lithosphere is consumed. Slow‐spreading may result in the Atlantic lithosphere being more pervasively and heterogeneously hydrated than fast‐spreading Pacific ...

The Role of Salt Tectonics in the 2021 Central Adriatic Seismic Sequence

Earth and Space Science, Volume 12, Issue 5, May 2025.
Abstract On 27 March 2021 a 3‐months lasting seismic sequence struck the Central Adriatic Basin that is part of the Adria plate, a relatively undeformed plate since recent times. Analyzing the waveform data acquired by the Italian and Croatian seismic networks, we computed the location parameters of 160 earthquakes and the focal mechanisms of the Mw 5 ...
