... near-surface structures in Hangzhou City, Eastern China. Noise data were recorded by dense linear arrays with approximately 5 m spacing deployed along two crossing roads. We analyze the characteristics of traffic-induced noise using 36 h continuous recordings. Coherent Rayleigh surface waves between 2...

... reservoirs, buried less than 120 m (393.7 ft), have been discovered and successfully exploited in the Hangzhou Bay area, northern Zhejiang Province, eastern China. In this study, we describe the methods used for the exploration of shallow gas, including cone penetration test (CPT), shallow shear-wave seismic...

...C. M. Lin; L. X. Gu; G. Y. Li; Y. Y. Zhao; W. S. Jiang Abstract Late Quaternary shallow biogenic gas reservoirs have recently been discovered and exploited in the coastal Hangzhou Bay area, northern Zhejiang Province, eastern China. The river in this area strongly incised the underlying old beds...

... space-domain analytical solutions. We then apply the Fourier forward algorithms to the prediction of vertical component of gravity at many survey points, as a function of the water level of a reservoir located in Xianlin, Hangzhou, China. The reservoir geometry is approximated by a single vertical...

... with a sampling rate of 500 Hz and decimated to 100 Hz for computational efficiency. The first experiment is part of a geologic survey project along the Fengqi Road in Hangzhou, China. Near the survey area is an intersection as well as several nearby construction sites, generating ambient noise with strong...
