Passive seismic depth sounding by statistical array analysis
We can determine efficiently the Rayleigh wave dispersion curve for a frequency range between 2 Hz and 80 Hz by analyzing the seismic noise recorded on mini-arrays. Due to the short recording time of 15 min we are able to map an area up to 6 ha per day. The dispersion curve gives us a first qualitative image of the subsurface.
