Abstract
Beginning from April 13th, 2011, the Sendai Science museum, once or twice in a month, researched the plant damage caused by the tsunami of the Pacific Ocean tide Tohoku earthquake mainly in the Gamou and Sendai bay area. The results indicate that the plant damage should be separated into two causes, physical factor and salt ater.
The deciduous trees sustained less damage from salt water. Therefore, it is clear that the damage influenced the trees before they opened their leaves.
