The aim of this paper is to discuss the existing scientific literature in order to gather all the
available information dealing with the origin and the nature of the ambient seismic noise …

The ambient seismic wave field, also known as ambient noise, is excited by oceanic gravity
waves primarily. This can be categorized as seismic hum (1–20 mHz), primary microseisms …

Single-photon atom gradiometry is a powerful experimental technique that can be employed
to search for the oscillation of atomic transition energies induced by ultralight scalar dark …

The Earth undergoes continuous oscillations, and free oscillation peaks have been
consistently identified in seismic records in the frequency range 2–7 mHz (refs,), on days …

Observations show that the seismic normal modes of the Earth at frequencies near 10 mHz
are excited at a nearly constant level in the absence of large earthquakes. This background …

We developed a three‐step method for three‐dimensional (3‐D) S wave velocity
tomography by fitting synthetic cross spectra to the observed ones of ambient seismic noise …

Seismology has come a long way in providing insights into Earth's internal structure and
dynamics. Among many forward and inverse geophysical techniques developed, full …

Seismic interferometry has now been applied to the exploration of the Earth's interior at
scales ranging from local to global. Most studies have used surface‐wave propagation …

The seismic free oscillations of the Earth can be observed in the frequency band from 0.3 to
20 mHz, and estimates of their frequencies constitute the principal constraints for spherically …

The recent discovery that the seismic normal modes of the Earth are excited to a nearly
constant level during seismically quiet days ('the hum of the Earth') has lead to much …
