泉州地震台测震观测质量分析及技术对策

Analysis on the quality of seismic observation and its technical countermeasures in Quanzhou Seismic Station

通过对泉州地震台甚宽频带数字地震仪测震观测的台基地动噪声、监测能力、震级偏差和震相特征分析等方面的综合研究,提出了减少测震台基地动噪声影响、提高测震监测能力、减少震级偏差、提高震相分析水平、加强观测系统的维护、提高测震速报与地震编目的水平及规范观测质量的管理等方面相应的技术对策,有关研究结果对寻求和提高泉州台测震观测质量的技术途径等方面具有实际意义。

Through synthetic study on site ground noise,monitoring capability,magnitude deviation and seismic phase characteristics analysis etc of seismic observation of very broadband digital seismograph at Quanzhou Seismic Station, We proposed the corresponding technical countermeasures including action to reduce site ground noise in seismic observation, improve the seismic monitoring capability, reduce the magnitude deviation, improve the level of phase analysis,strengthen the maintenance of the observing system, improve the level of seismic quick report and earthquake catalog, and standardized the management of seismic observation quality etc. The research results have practical significance to seek and to improve the technical approaches etc in the quality of seismic observation at Quanzhou Seismic Station
