| Abstract: | The 10 three-component acceleration records of Wuqia earthquake, on Jun. 10, 2010 was processed and analyzed preliminary. After the data format of the original seismic records was trans-formed and the base lined was corrected, the author calculated the corrected acceleration, velocity and displacement and FAS response spectra, acceleration response spectra before the normal analysis processing. We found that higher peak of acceleration distributed along seismogenic fault and focused on narrow area near the fault, In addition, the maximum frequency of acceleration records near fault is relatively larger after the strong ground motions characteristics of Wuqia earthquake was analyzed. Finally the spatial distributions of the PGA are plotted. |
