英文摘要 | Using recordings of a mine collapse event (M-w 4.2) in South Korea in January 2015, we demonstrated that the phase and amplitude information of impulse response functions (IRFs) can be effectively retrieved using seismic interferometry. This event is equivalent to a single downward force at shallow depth. Using quantitative metrics, we compared three different seismic interferometry techniquesdeconvolution, coherency, and cross correlationto extract the IRFs between two distant stations with ambient seismic noise data. The azimuthal dependency of the source distribution of the ambient noise was also evaluated. We found that deconvolution is the best method for extracting IRFs from ambient seismic noise within the period band of 2-10s. The coherency method is also effective if appropriate spectral normalization or whitening schemes are applied during the data processing. |
