A source function is imaged by applying the adjoint wave propagation operator to the receiver field. Our experiments show that the origin time and the source location depend on the background velocity model, while a lack of detailed features in the velocity model may introduce artifacts to the image. We apply full waveform inversion to time-lapse passive seismic data to estimate velocity changes over time. Our method estimates small 4D velocity changes surprisingly well, even for a single passive seismic source event.
