Identifying P phase arrival of weak events: The Akaike Information Criterion picking application based on the Empirical Mode Decomposition
X Li, X Shang, A Morales-Esteban, Z Wang - Computers & Geosciences, 2017 - Elsevier
Seismic P phase arrival picking of weak events is a difficult problem in seismology. The
algorithm proposed in this research is based on Empirical Mode Decomposition (EMD) and
on the Akaike Information Criterion (AIC) picker. It has been called the EMD-AIC picker. The
EMD is a self-adaptive signal decomposition method that not only improves Signal to Noise
Ratio (SNR) but also retains P phase arrival information. Then, P phase arrival picking has
been determined by applying the AIC picker to the selected main Intrinsic Mode Functions …
