A Feasibility Study on Monitoring Crustal Structure Variations by Direct Comparison of Surface Wave Dispersion Curves from Ambient Seismic Noise

<div>Cross-correlations of three months of noise data (January to March 2010) between ESPZ and JUBA, with a path length of approximately 154 km. The amplitude spectrum is also shown to the right of each waveform. (a) Symmetric-component of the cross-correlation (folded signal). (b) The negative part of the cross-correlation. (c) The positive part of the cross-correlation. The negative and positive parts of the cross-correlation represent two opposite directions of wave propagation between two receivers.</div>
