Abstract The Sendai Framework for Disaster Risk Reduction 2015–2030 (SFDRR) highlights
the importance of scientific research, supporting the 'availability and application of science …

Recent research has shown that noise can be turned from a nuisance into a useful seismic
source. In seismology and other fields in science and engineering, the estimation of the …

The term seismic interferometry refers to the principle of generating new seismic responses
by crosscorrelating seismic observations at different receiver locations. The first version of …

Previously a Bayesian theory for modal identification using the fast Fourier transform (FFT) of
ambient data was formulated. That method provides a rigorous way for obtaining modal …

In the 1990s, the method of time-reversed acoustics was developed. This method exploits
the fact that the acoustic wave equation for a lossless medium is invariant for time reversal …

Cross correlation of the ambient seismic field is now routinely used to measure seismic
wave travel times; however, relatively little attention has been paid to other information that …

Wave travel times of vertically propagating waves are measured in the Van Nuys 7‐storey
hotel, located in the Los Angeles metropolitan area, from impulse response functions …

For health monitoring of a building, we need to separate the response of the building to an
earthquake from the imprint of soil‐structure coupling and from wave propagation below the …

The extraction of the response from field fluctuations excited by random sources has
received considerable attention in a variety of different fields. We present three methods for …

Nonlinear elasticity is evidenced by the variation of the elastic properties of a system under
slight strain and their recovery after loading. These characteristics have been previously …
