This simulation
(7.7 MB) of the 1994 East Java tsunami was developed by Nobuya
Horiuchi of the Disaster Control Research Center, Tohoku University,
Japan. It shows the initial water-surface profile over the source
area and the subsequent wave propagation away from the source.
Areas in blue represent a water surface that is lower than the
mean water level, while areas in red represent an elevated water
surface.
