Reducing horizontal to vertical spectral ratios of ambient vibrations measured at the sea bottom to inland equivalent values

摘要

A simple procedure is proposed to reduce horizontal to vertical spectral ratio curves relative to ambient vibrations measured at the sea bottom to equivalent curves measured inland. The procedure does not rely on specific assumptions about the nature of ambient vibrations and allows extending inversion techniques developed for the interpretation of spectral ratio measurements inland to sea floor observations.
