Revealing Very Shallow Structures in a Heterogeneous Dyke through Interferometric Subtraction of Surface Waves in a Seis

Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review

Abstract

It is challenging to image the very shallow structures in a heterogeneous dyke using traditional geophysical methods. With the aim to reveal these structures, a low-budget seismic S-wave reflection survey was carried out over a dyke with a fixed-receivers array. We applied seismic interferometry to this dataset in order to retrieve
surface waves and then adaptively subtracted these surface waves from the original recordings. Combined interpretation of the stacked images obtained from the original data and that from the data after adaptive subtraction reveals more complete shallow structures inside the dyke.
