2009年2~4月,柯坪块体先后发生了3次5级地震。新疆地震局布设在南天山西段数字强震动台网获取了这3次地震的主震加速度记录。文中对3次地震加速度记录进行了常规数据处理。按地震动三要素计算了地震烈度,并将计算的烈度与地震宏观考察烈度进行了比较。
From February to April 2009, three M5 earthquakes occurred in the Keping block. Xinjiang Seismological Bureau located in the western section of South Tianshan Digital Strong Motion Network acquired the main shock acceleration records of these three earthquakes. In this paper, three earthquake acceleration records were processed by conventional data. The earthquake intensity is calculated according to the three elements of earthquake and the intensity of the earthquake is compared with the intensity of macro-survey.
