Coda waves are highly sensitive to changes in the subsurface; we use this sensitivity to monitor small stress changes in an underground mine. We apply coda wave interferometry to seismic data excited by a hammer source, collected at an experimental hard rock ...

In this paper the conventional approach to pipeline stability design is reviewed and compared with experiments. A failure mechanism of pipelines on liquefied seabeds is analyzed. An analytical model to predict the pipelines sinking depth is proposed, and the ...
