Improving the Retrieval of Offshore-Onshore Correlation Functions With Machine Learning

Viens Loïc , Iwata Tomotaka

… However, localized ambient seismic field sources between offshore and onshore stations can bias correlation functions and generate nonphysical arrivals. … For a DF data set calculated between two stations over a long time period, we first reduce the data set dimensions using the principal component analysis and cluster the features of the low‐dimensional space with a Gaussian mixture model. …

Applicability of phase velocity estimation method using Green's functions with a common virtual source from seismic interferometry - In the case of the Wakasa bay region considering asymmetry of cross-correlation functions of ambient noise - [in Japanese]

Suzuki Kyohei , Sato Hiroaki

… <p>In this study, in order to examine the applicability of phase velocity estimation method using Green's functions with a common virtual source by seismic interferometry, we conducted continuous seismic observation at 16 points in Wakasa Bay region, and estimated the phase velocity by using both the positive side of the cross correlation function having large amplitude and the negative side of the cross correlation function having small amplitude, and compared the both results. …
