| Abstract | The March 11, 2011 tsunami caused serious damage to many buildings, bridges and lifelines, and 18,771 people were killed and missing in Japan (data on 2012, July 25). From this event, the digital videos on the damage of structures and the tsunami flows were recorded and uploaded to open web sites. The tsunami flow velocity on land is estimated by using image processing of videos and estimating the dimension of the moving and reference objects. The analyzed tsunami flow velocities range about 2.9 4.9 m/s in Kamaishi town, 2.1 2.8 m/s in Ofunato town, 2.6 5.4 m/s in Kesennuma town, 1.4 m/s in Iwaki town and 2.6 m/s in Oarai town. Finally, the analyzed tsunami flow velocities are used to validate the tsunami velocity from the tsunami inundation simulation for this event. The tsunami flow velocities from the simulation results have the similar trend with the tsunami flow velocities by image processing of videos; however, most of them are less than the results by image processing of videos. |
