abstract = "In this work, we examine the vertical component (Z) of the
geomagnetic field observed by ground-based observatories during
the tsunami event which happened on 11 March 2011. For this event,
we have selected nine magnetic observatories distributed along the
tsunami passage, covering up to 3000 km epicentral distance. The
traveltime diagram of the magnetic disturbances is constructed and
compared with the simulated tsunami traveltime diagram. From this
comparison, we identify the amplified magnetic disturbances
appearing during the tsunami arrival in the vicinity of these
observatories. Moreover, mean absolute percentage error map is
constructed to examine the cross correlations among different
observatories and the amplified disturbances are found to be
highly correlated. These features suggest that the amplified
disturbances are tsunamigenic in nature. These results are in
confirmation with the previous near-field studies, and they shed
new insight into the tsunamigenic magnetic disturbances on near-
and far-field distances from the epicenter.",
