abstract = "This study reports the magnetic disturbances due to the Chilean
tsunami (2015). Using 10 ground-based magnetometer observatories
spread in the Pacific Ocean, covering approximately 150º
epicentral distance, for a time duration of 24 h from the tsunami
initiation, tsunamigenic disturbances in the Z-component of the
geomagnetic field are investigated. The methodologies namely, the
discrete wavelet transform (DWT), the newly developed approach
called effectiveness wavelet coefficient (EWC), and intrinsic mode
functions (IMF) decomposition are implemented to detect these
tsunamigenic disturbances. The analysis reveals the presence of an
increase of EWC amplitude due to tsunamigenic magnetic
disturbances nearly around the tsunami arrival time at each
observatory. The IMF decomposition analysis using 1040 min levels
of decomposition shows the amplified magnetic disturbances around
the time of the increase in EWC amplitude. In most of the
observatories, the time of the amplified EWC is consistent with
the approximate time of the tsunami arrival, while in the other
observatories, the IMF decomposition provides better consistency.
The results suggest that the methodologies implemented in the
present work can be effectively used to characterize the
tsunamigenic contributions in the geomagnetic field, since the
tsunami wavefront propagates towards the Pacific Ocean covers the
time duration as long as 24 h from the tsunami initiation.",
