A scalable algorithm for cross-correlations of compressed ambient seismic noise

SEG Technical Program Expanded Abstracts 2019, 2019
Companies and academic geophysicists are increasingly collecting continuous seismic data on denser arrays, and are looking to a variety of lossy compression methods to store and quickly access this data. Some researchers turn to ambient noise interferometry for low-cost near-surface imaging to avoid to cost and permitting required for active source ...
