Tsunami-tide interactions implied from the 2011 tohoku tsunami records analysis using hilbert-huang transform
Author : HAN SOO LEE(1), ()
ABSTRACT
We have investigate the 2011 Tohoku Tsunami records in the Seto Inland Sea (SIS) in western Japan using Hilbert-
Huang Transform. The SIS consists of many bays and basins such as Osaka bay and Hiuchi basin with their natural
oscillation characteristics. The resulting intrinsic mode functions obtained from ensemble empirical model
decomposition revealed that the tsunami propagated into the SIS interacts with natural oscillations of bays and is also
affected by high tides in the SIS. During high tides, the maximum tsunami heights and arrival times are enhanced and
shortened significantly from those at low tides.
