基于Python爬虫技术的高精度地震目录更新程序的设计与应用

首先,基于Python爬虫技术,实现了高精度定位结果的地震目录的自动下载;然后,针对省局台网快报目录汇总后存在重复定位地震的问题,提出了一种能够有效筛除重复定位地震的方法;最后,分析EQ3格式地震目录的二进制结构,实现了高精度定位结果的地震目录向EQ3格式的转换。实际应用表明,该程序能够显著提高EQ3格式地震目录更新的工作效率,更高定位精度的地震目录也有助于对地震活动性进行深入分析。

Design and Application of High Resolution Earthquake Catalogue Auto Update Program Based on Python Crawler Technology

We first use the Python crawler technic to download the high resolution earthquake catalogue automatically. We proposed an effective repeat earthquake elimination method to remove the repeat earthquakes among different catalogues uploaded from different provincial earthquake bureaus. In the end,we transform the high resolution earthquake catalogue to EQ3 format based on the research of its binary structure. Practical application shows that the proposed program can improve the efficiency of the update of earthquake catalogue. In addition,high resolution earthquake catalogue is beneficial for us to analyze seismicity more deeply.
