Distributed acoustic sensing (DAS) is one recently developed seismic acquisition technique
that is based on fiber-optic sensing. DAS provides dense spatial spacing that is useful to
image shallow structure with surface waves. To test the feasibility of DAS in shallow structure
imaging, the PoroTomo team conducted a DAS experiment with the vibroseis truck T-Rex in
Brady's Hot Springs, Nevada, USA. The Rayleigh waves excited by the vertical mode of the
vibroseis truck were analyzed with the Multichannel Analysis of Surface Waves (MASW) …

Distributed acoustic sensing (DAS) is one recently developed seismic acquisition technique
that is based on fiber-optic sensing. DAS provides dense spatial spacing that is useful to
image shallow structure with surface waves. The 8700-m Distributed Acoustic Sensing
(DAS) cable was deployed at Brady's Hot Springs, Nevada in March 2016 and it recorded
swept-frequency signals by the vibroseis truck T-Rex excited at about 66 vibe points. The
Rayleigh wave excited by the vertical mode of T-Rex was analyzed with the Multichannel …
