Imaging with ambient seismic noise: Beyond surface-wave microseisms
Vibrations from cars driving in Long Beach, CA, provide signal that can be harnessed for estimating seismic velocities.
Interface and acoustic waves can be obtained from passive shallow ocean-bottom node data.
Temporal changes in electrical conductivity provide insight into soil characterization of the vadose zone.
