Abstract:From the digital waveforms recorded from 2013 to 2015 by the digital seismic network of the core water source area for the central line project of the south-to-north water diversion, we select the digital waveforms of 141 earthquakes with ML≥1.5. The Q values of the structure beneath the core water area are calculated by analyzing seismic waveforms using Atkinson’s method. The results show that the average Q value depends on frequency by Q=146.0*f(0.770 3), and this moderate Q value indicates that this region is in anactive tectonic period at present.
