Characterizing Ambient Seismic Noise in an Urban Park Environment [PDF]

Sensors, 2023
In this study, a method for characterizing ambient seismic noise in an urban park using a pair of Tromino3G+ seismographs simultaneously recording high-gain velocity along two axes (north-south and east-west) is presented.

Seismic Attenuation Extraction From Traffic Signals Recorded by a Single Seismic Station

Geophysical Research Letters, 2023
Seismic ambient noise contains rich information about the physical properties of the critical zone. From the motor vehicle noise, we extract the daily seismic attenuation by quantifying the linear relationship between the frequency and amplitude ratio of

Continuous isolated noise sources induce repeating waves in the coda of ambient noise correlations

Seismica, 2023
Continuous excitation of isolated noise sources leads to repeating wave arrivals in cross correlations of ambient seismic noise, including throughout their coda. These waves propagate from the isolated sources.
