Identifying Earthquakes in Low-Cost Sensor Signals Contaminated with Vehicular Noise

open access: yesApplied Sciences, 2023
The importance of monitoring earthquakes for disaster management, public safety, and scientific research can hardly be overstated. The emergence of low-cost seismic sensors offers potential for widespread deployment due to their affordability ...

Fiber optic interferometric seismometer with phase feedback control.

open access: yesOptics Express, 2020
A high-sensitivity ultralow-frequency fiber optic interferometric seismometer using phase feedback control is proposed and demonstrated. The principle of sensitivity improvement using feedback is described, and the characteristics of the seismometer ...

Optimization of seismometer arrays for the cancellation of Newtonian noise from seismic body waves [PDF]

open access: yesClassical and quantum gravity, 2019
Newtonian noise (NN) from seismic fields is predicted to become a sensitivity limiting noise contribution of the gravitational-wave detectors Advanced LIGO and Virgo in the next few years.

Large Dynamic Range and High Sensitivity PGC Demodulation Technique for Tri-Component Fiber Optic Seismometer

open access: yesIEEE Access, 2020
Three-component fiber optic seismometers are widely used in the detection of seismic signals. The arctangent approach of phase-generated carrier (PGC-Arctan) demodulation algorithm is one of the commonly used demodulation techniques in FOISs.

Coastal cliff ground motions and response to extreme storm waves [PDF]

open access: yes, 2015
Coastal cliff erosion from storm waves is observed worldwide, but the processes are notoriously difficult to measure during extreme storm wave conditions when most erosion normally occurs, limiting our understanding of cliff processes.
