据中国地震台网正式测定:02月06日09时17分,在土耳其(北纬37.15度,东经36.95度)发生7.8级地震,震源深度20公里。
地震后强震动观测中心收集获取了距震中483公里范围内强震动记录263组,并迅速组织人员进行处理。获取记录台站加速度记录分析结果见表1(节选部分),其中4614台PGA峰值最大,其震中距为42.4km,东西、南北、垂直向加速度峰值分别为-1968.8cm/s2、1962.5cm/ s2、1347.9cm/ s2,东西、南北、垂直向速度峰值分别为-51.3cm/s、66.8cm/s、-28.5cm/s,计算仪器地震烈度9.5度。
仪器地震烈度分布图见图1,地震峰值加速度分布图见图2,地震峰值速度分布图见图3,地震加速度反应谱(T=0.3s、T=1.0s、T=3.0s)分布图见图4、图5、图6。4614台强震动记录见图7,4614台加速度反应谱见图8,4614台傅里叶幅值谱见图9。
