Boundary problems Real Life Example. Left: Adapted from Sarlis et al. paper103. EMD decomposition of the magnitude time-series of GCMT collected from 1 January 1976 to 1 October 2014. The red boxes highlight artifact wave peaks at the boundaries of the IMFs, while the blue asterisks pinpoint anomalous IMFs amplitudes (larger than the original signal). Right: Decomposition of the GCMT magnitude time-series from January 1st 1976 to October 1st 2014 produced using the EEMD function released on March 04 2009 by Zhaohua Wu. The red line in each panel represents the zero reference line. Total computational time: 213.9069 s.
