Figure 8From: Characterization of ambient seismic noise near a deep geothermal reservoir and implications for interferometric methods: a case study in northern Alsace, France Vertical component cross-correlation functions measured between stations RITT and BETS and band-pass filtered between 0.2- and 0.5-s period. The waveforms are averaged separately depending on the day of the week over 2 years. Bottom: zoom between 8 and 10 s of correlation lag time.Back to article page
