Introduction High-resolution seismic reflection has been successfully used to delineate preferential pathways within groundwater systems that represent corridors for contaminant movement in a wide variety of challenging hydrologic settings, many in settings where other methods and/or monitor wells have not been enlightening. For more than four decades, seismic reflection has found utility addre...

Seismic reflection can provide precise estimates of subsurface structures. To obtain more information on subsurfaces using the same amount data, we first compared reverse time migration (RTM) images obtained from surface seismic profile (SSP), vertical (VSP), and single well (SWP) data for models that included faults with various dips. When were sufficient, SSP, SWP, VSP surveys suitable identi...

Introduction: Several experiments performed by the astronauts on the Moon (e.g., the Apollo Lunar Surface Experiments Package, ASLEP), and proposed experiments as ground-prep for the return of humans to the Moon (RPLP-2/LPRP-2) involve the use of seismic (acoustic) energy for exploration. These seismic signals can be used for a wide array of purposes, from imaging the Lunar interior to detectin...

We review the resolution currently available with seismic tomography, in particular the ability of seismic waves to image mantle plumes, and discuss frequently asked questions about artifacts, interpretation and possible systematic errors. These aspects are discussed in more detail for two case histories offering different problems in the tomographic interpretation: Iceland and Hawaii. Regional...
