海南区域量规函数与台网震级的研究

Study of the Calibration Function and the Magnitude of Seismic Network in Hainan

选取海南数字台网其中4个台站记录到的地震资料,资料时间从2009年1月至2016年8月,总计280条地震,累计样本数3 006个,通过震级残差统计方法计算各子台震级与台网震级的偏差、平均偏差和标准偏差,分析震级偏差频次分布,修正了海南地区880 km以内的ML量规函数。

The paper selects the seismic data recorded by the 4 stations of Hainan seismic network, which are from January 2009 to August 2016, with a total of 280 earthquake, and the cumulative number of samples 3006. The paper calculates the deviation, average deviation and standard deviation between the substation magnitude and network magnitude by the statistic method of magnitude residuals deviation, analyzes the distribution of the deviation frequency of magnitude, and modifies MLcalibration function within 800 km of Hainan region.
