This paper presents an analysis of applying continuous wavelet transform spectrum analysis to the results of laboratory measurement of landslide-generated impulse waves. As the measured results are understandably unsteady, nonlinear, and non-stationary, the application of time-localized wavelet transform analysis is shown to be a suitable as well as useful approach. The analysis on correlating the time-frequency wavelet spectrum configurations in connection with the ambient parameters that drive the impulse wave process, with respect to time and space, leads to interesting and stimulating insights not previously known.
