2013年甘肃岷县—漳县6.6级地震仪器烈度与宏观调查烈度比较分析
A Comparison and Analysis of Instrumental Intensity and Macroseismic Survey Intensity of the 2013 Minxian—Zhangxian MS6.6 Earthquake in Gansu Province
摘要
Abstract
On July 22,2013,an MS6.6 earthquake occurred at the border area between Minxian and Zhangxian Counties,Gansu Province.In this study,1 1 7 groups of three-component accelera-tion records collected by the Northwestern Strong Motion Networks Center were processed and analyzed,and the resultant instrumental intensity values were calculated and analyzed.The in-strumental intensities and the intensities obtained from the Minxian-Zhangxian seismic intensity map (China Earthquake Administration,2013)were compared and analyzed,and the stations with deviations less than 1 degree were determined to account for 81.8%.The instrumental inten-sities and the intensities of surveying points within 5 km around the stations were also compared, and the stations with the same intensity account for 50%.The disaster investigation and analysis indicate that most buildings in the Minxian-Zhangxian earthquake-stricken area are of civil and wood structures,and they are more heavily damaged than other regions that experienced the earthquake at the same intensity.Although the instrumental intensity is not quite consistent with the microseismic intensity,the instrumental intensity reflects the earthquake disaster to a certain extent and provides the basis for determining emergency rescue.关键词
