Ambient-noise measurements for seismic risk mitigation of school buildings
Environmental Semeiotics, 2011Abstract: Seismic risk management of relevant and strategic structures is a notable issue in seismic Italian codes. In order to delineate a rational strategy for seismic risk mitigation on a wide territory, it is necessary to create some decision-making tools useful to define a prioritization of intervention.

Extracting Stable Seismic Core Phases from Ambient Seismic Noise
Bulletin of the Seismological Society of America, 2015Abstract Ambient seismic‐noise correlation is a powerful tool for extracting the seismic core phases that propagate through the interior of the Earth. In this study, we present and refine the root‐mean‐square‐stacking method to extract stable core phases (e.g., PcP , ScS , PcS / ScP , and PKiKP ) from within the Central Alborz region, Iran, using ...

Exploiting Seismic Waveforms of Ambient Noise and Earthquakes
2014In this thesis, I apply detailed waveform modeling to study noise correlations in different environments, and earthquake waveforms for source parameters and velocity structure. Green's functions from ambient noise correlations have primarily been used for travel-time measurement.

Interpreting seismic velocity changes observed with ambient seismic noise correlations
Interpretation, 2016Abstract Recent results have shown that crosscorrelating ambient seismic noise recorded in underground mines can successfully extract the seismic Green’s function between sensors. We have revisited an earlier experiment that showed that these virtual seismic sources can be used to measure changes in seismic velocity accurately enough ...

Ambient seismic noise below the deep seafloor
The Leading Edge, 2000Knowledge of ambient noise levels and of the physical mechanisms responsible for ambient noise is essential to optimize the return from a seismic acquisition system in petroleum exploration or reservoir monitoring. The ultimate goal of a seismic survey is to give the best image of the subsurface that the earth will allow for a given budget.

Seismic attenuation from seismic ambient noise recordings
The eastern part of the Vienna Basin represents Austria's primary target for deep geothermal exploration. Effective geothermal resource assessment requires detailed knowledge of subsurface rock properties, including porosity, permeability, and fluid content.openaire +1 more source

Ambient Seismic Noise: From Characterization to Simulation
Ambient seismic noise, traditionally viewed as undesired signal in seismic records, has increasingly gained importance as a source of information for site characterization and seismic monitoring. With the growing demand for exploitation of alternative energy resources (e.g.Abdullah A. Abdulghany +4 more

Seismic Ambient Noise Analysis of the Indian Subcontinent
Seismic ambient noise has three bands- cultural noise, microseism noise, and infra-gravity waves. In this study, we have considered two bands: cultural noise and microseism noise. Anthropogenic activities generate cultural noise(1-10Hz), whereas ocean, atmosphere, and solid earth interaction lead to the genesis of microseism noise (0.05-1Hz).
