Abstract

OBS data are exposed to additional noise sources like tilt and compliance. We show that the data can be enhanced prior to the usage of standardised land seismology techniques, such as ambient noise tomography. We do this by estimating group velocities before and after enhancing the signal. This project is part of AlpArray and aims to improve the understanding of the proposed subduction polarity change between the Alpine and Apennine subduction.
