Strong Motion Observation Records and Seismic Intensity of the Ning'er M_S6.4 Earthquake

Four strong motion record stations had been located in Ⅵ degrees above seismic intensity zone or the nearby on June 3,2007 Ning'er MS6.4 earthquake struck area.We recorded larger main-earthquake acceleration recordd by them.The paper describes seismogenic and seismicity at the venue of four strong motion record stations.We introduced the parameters of the strong motion records.We described investigation methods and results of earthquake disaster for the four fields,and determined the seismic intensity,and compared with seismic intensity by the maximum peak acceleration in accordance.We analyzed differences of seismic intensity between four strong motion records and actual scene investigation records.We discussed reasons of differences for seismic intensity too.
