URBAN SEISMIC AMBIENT NOISE ANALYSIS: INNOVATIONS AND APPLICATIONS
Seismic ambient noise generated by human activities provides an opportunity to monitor aboveground human activities without intruding on privacy. However, extracting specific signals from noisy seismic noise is challenging. Seismic ambient noise also contains information about the underground …

Monitoring and Imaging Seismic Velocity Changes Across Temporal and Spatial Scales
Relative changes in seismic velocity (dv/v) are associated with changes in mechanical properties of crustal materials, and can reflect the perturbations in stress fields, rock damage, and fluid content. Interferometry of seismic ambient noise enables the continuous monitoring of dv/v. In this …

Towards monitoring volcanoes in Iceland and Hawai’i with seismic velocity variations
Seismic noise interferometry is an exciting technique for studying volcanoes because it provides a continuous measurement of relative seismic velocity (dv/v), which is sensitive to magmatic processes that affect the physical properties of the surrounding crust. However, understanding the causal …
