Nondestructive testing of railway embankments by measuring multi-modal dispersion of surface waves induced by high-speed trains with linear geophone arrays

Seismica
To effectively address engineering challenges and risks, it is crucial to characterize mechanical properties of near-surface environments. The Multichannel Analysis of Surface Waves (MASW) has proven to be a valuable active seismic imaging technique by ...

The impact of COVID-19 lockdown measures on high-frequency seismic ambient noise in Greece: Utilizing strong-motion seismograph networks for human activity monitoring in urban environments

Seismica
Vibrations generated by anthropogenic activity propagate into the Earth’s subsurface as high-frequency seismic waves. The Covid-19 pandemic, which prompted widespread adoption of prevention policies in 2020, including social distancing measures, stay-at-
