鹤岗地震台测震观测资料质量分析与研究
|
摘要
通过对鹤岗地震台测震观测资料和国家测震观测资料评比标准进行分析比较,在保证观测仪器正常运转的情况下,认为要提高鹤岗地震台测震观测资料质量,就要做好震相分析、震级测定、数据报送、单台报告四方面的工作,其中震相分析精度是保证观测资料质量的关键,而初至波震相的精度决定了震相分析的精度,所以对如何提高初至波震相精度进行了分析,并提出了几点改善工作的建议。
Based on the observation data of Hegang seismic station and the national seismic observation data of evaluation standards were analyzed and compared, in ensuring the normal operation of the observation instrument case, think to want to enhance the Hegang seismic station observation data quality, it is necessary to do the seismic phase analysis, magnitude determination, data reporting, four single report the work, which is the key to ensure the accuracy of seismic phase analysis of observation data quality, and beginning to the accuracy of wave phase determines the phase analysis precision and so on how to improve the precision of phase beginning to wave are analyzed, and puts forward some improving proposals for the work.
