We propose a hybrid surface wave imaging method based on the fusion of conventional active seismic imaging and ambient noise interferometry. This leads to an innovative combination of fast and easy acquisition and robust and accurate processing. Unlike ambient noise interferometry, the “noise” is stimulated by a fast and uncontrolled hammering sequence. Then, advanced algorithms based on the matched-field method are used to extract precise surface wave information from the stimulated noise data. Some examples are presented to illustrate the capabilities of the method, showing very accurate and reliable results thanks to a fast and easy-to-use solution.
