Spectral Analysis of the Recorded Ambient Vibration at a Mass Movement in Brasilia

A spectral analysis of ambient vibrations at a mass movement site in Brasília, Brazil, reveals strong correlations between noise frequency content and man-induced emissions, particularly from nearby carbonate mining. The study utilized Power Spectral Density (PSD) to characterize noise sources, employing 10 short-period seismometers with a natural frequency response of 2 Hz, recorded at a sampling rate of 250 samples per second. Preliminary findings suggest that while human activities significantly influence vibration patterns, future research will focus on natural factors such as rainfall-induced saturation and seismic activity to better understand their role in altering mechanical properties and landslide dynamics.
