             abstract = "A challenging task is to separate tsunamigenic variations in the 
                         geomagnetic field measurements in the presence of more dominating 
                         magnetic variations by currents in the inner core of the Earth and 
                         by ionospheric currents. To decode tsunamigenic contributions, 
                         spatio-temporal multi-data analyses are required to be implemented 
                         in an integrated manner. In this work, we present one integrated 
                         framework that has shown enormous potential and efficiency to 
                         retrieve tsunamigenic contributions from the geomagnetic field 
                         measurements. We select the Maule (2010) tsunami event occurred on 
                         west coast of Chile, and examine geomagnetic measurements from 9 
                         ground magnetometers scattered in the pacific ocean covering a 
                         wide area of ~60°. Employing the integrated analysis framework, 
                         two kind of tsunamigenic contributions are identified, one arising 
                         from direct ocean motion and another from atmospheric motion, both 
                         associated with the tsunami forcing. Moreover, in spite of tsunami 
                         waves are considerably subsidized with increasing epicentral 
                         distance, the tsunamigenic contributions are retrieved from a far 
                         away magnetic observatory at Australia. These results suggest that 
                         various kinds of tsunamigenic disturbances can be well-identified 
                         from the integrated analysis framework presented here.",
