| Abstract: | The data gained by emergency mobile strong-motion observation of the aftershock of Yao'an M6.0 earthquake on July 9,2009 are processed and analyzed,including filtering,baseline correction of their acceleration trace,calculation of the PGA,PGV,PGD,PSV,PSD,spectrum intensity(SI) and Td of M5.2,M4.7 and M4.6 aftershocks.The results indicate that filter processing of the near field records of aftershocks evidently affects the high frequency component,but its effect on the low frequency component is little;The m... |
