利用C语言编程实现SAC到EDAS数据格式的转换

Using C programing language to convert seismic waveform format from SAC to EDAS

"4·20"芦山7.0级大地震以后,随着科考台站的架设,从该地区台阵获得了海量的地震信息。本文通过C语言编程实现了将SAC格式的地震单台波形数据进行自动截取并转换为港震EDAS格式的地震事件数据形式,不仅大大提高了工作效率,同时也为后续的研究(如研究区域S波分裂、泊松比分布以及地壳流分布空间和流动方式等)打下坚实的基础。

After the M7. 0 Lushan Earthquake on 20 April 2013,a lot of new instrument were installed. We get a huge of seismic data from the seismic observation array around the disaster area. We use the C programing language to convert the data with SAC format into EDAS. It greatly improves the efficiency and lays a solid foundation for further research as well.
