N2 - We propose a seismic scanning tunneling macroscope (SSTM) that can detect and distinguish subwavelength scatterers in the near-field of either the source or the receivers. Analytic formulas for the time reverse mirror (TRM) profile associated with a single scatterer model show that the spatial resolution limit to be, unlike the Abbe limit of λ/2, independent of wavelength and linearly proportional to the sourcescatterer separation as long as the scatterer is in the near-field region. This means that, as the scatterer approaches the source, spatial imaging with super-resolution can be achieved. This is analogous to an optical scanning tunneling microscope that has sub-wavelength resolution. Scaled to seismic frequencies, it is theoretically possible to extract 100 Hz information from 20 Hz data by imaging of near-field seismic energy.
