摘要

本文提出了利用变分模态分解(VMD)作为分析与强震事件有关的地震加速度信号的一种替代技术。采用2016年4月厄瓜多尔Pedernales 7.8级地震期间不同站点记录的几个加速度信号对提出的方法进行了测试。信号分解分析允许创建热图，以便更好地可视化和解释地震的行波和衰减频率现象。所得结果与Pedernales地震的研究结果一致。

On the Analysis of Strong Earthquake Seismic Signals Using Variational-Mode Decomposition

In this paper, the use of Variational-mode decomposition (VMD) is proposed as an alternative technique for the analysis of the seismic accelerogram signals related to strong earthquake events. The proposed method was tested using several accelerogram signals recorded at different stations during the Mw 7.8 Pedernales earthquake, Ecuador in April 2016. Signal decomposition analysis allowed to create heat maps for better visualization and interpretation of the earthquake’s travelling wave and the attenuation frequency phenomena. The results obtained agree with seismic studies about the Pedernales earthquake.
