河北昌黎M 4.2地震强震动记录分析
Analysis of strong motion records of ChangliM 4.2 earthquake in Hebei Province
摘要
Abstract
Two earthquakes ofM 4.2 andM 3.3 occurred in Changli, Hebei Province on September 14, 2015, with a 13 minute interval and similar epicenters. The near-earth ifeld ground motion of ChangliM 4.2 earthquake is recorded by 6 strong motion stations of Hebei Strong Motion Network and 6 portable stations which were built in background ifled project of National Strong Motion Network Center. The maximum acceleration recorded by Qingtuoying Seismic Station is 33.5 cm·s-2. According to the analysis of the response spectrum and the Fourier spectrum of the strong motion recording of Changli M 4.2 earthquake, and the comparison between the soil and bedrock stations strong motion recording characteristics, the instrument intensity of the nearest station derived from the strong motion data is about V, basically same as the rapid intensity and disaster assessment macro intensity. The similarity can fully relfect the role and effect of the strong motion network construction.关键词
