An inverse source problem for elastic waves in isotropic homogeneous media is considered and a Fourier transform based multi-frequency approach to determine the elastic source is proposed. This is an easily implementable fast non-iterative inversion scheme. The stability estimate is derived. Numerical examples demonstrate the effectiveness of the method.
