                         tsunami (2015). Using 10 ground-based magnetometer observatories 
                         spread in the Pacific Ocean, covering approximately 150 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.",
