Seismic Gradiometry using Ambient Seismic Noise in an Anisotropic Earth

Event-driven Seismic Interferometry with Ambient Seismic Noise

SUMMARY By cross-correlating recordings of ambient seismic noise, one can retrieve the subsurface reflection response. The quality of the retrieved reflections would depend on the qualities of the ambient noise. In a previous study, we cross-correlated ambient-noise data recorded in a desert area in North Africa and showed that we retrieved reflections. This was done assuming that body-wave noi...

Characteristics of ambient seismic noise as a source for 2 surface wave tomography

6 [1] Interstation cross correlations of ambient seismic noise from 1 year of continuous data at periods 7 between 6 and 50 s are used to study the origin of the ambient noise using stations located in Europe, 8 southern Africa, Asia, and three regions within North America. The signal-to-noise ratios (SNR) of 9 Rayleigh waves for positive and negative correlation time lags at periods of 8, 14, ...

Fundamental and higher-mode Rayleigh wave characteristics of ambient seismic noise in New Zealand

[1] In order to use ambient seismic noise for mapping Earth’s structure, it is important to understand the spatiotemporal characteristics of the noise field. This study uses data collected during four austral winter months of 2002 to investigate New Zealand’s ambient seismic noise field in the double-ocean-wave-frequency range (0.1–0.3 Hz). It is shown via beamforming analysis that there are tw...
