    Abstract
    A robust imaging technology is reviewed that provide subsurface information in near-surface environments: wave-equation skeletonized inversion of surface waves for the S-velocity model and quality factor (Qs) structure. We demonstrate the benefits and liabilities of the method with synthetic seismograms and field data. The benefit of skeletonized inversion method is that it has higher resolution than the conventional 1D method and mostly avoids getting stuck in local minima. The synthetic and field data examples demonstrate that it is a robust method so that the complex near-surface structure can be reliably obtained with seismic surveys over near-surface environment. It is easily extended to anisotropic media or rugged topography seismic survey. The liability is that is almost as expensive as full-waveform inversion (FWI) and the resolution almost lower than FWI method.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
