Japan Tsunami in 2011 have been noted by the whole world. A great tsunami had stroke 
the northern coast of Taiwan in 1867. The study area is focused on Jinshan District and 
Wanli District, New Taipei City. The assumed earthquake scenario is used for Cornell 
University tsunami model (COMCOT model) which simulates the wave height and wave 
speed of the tsunami triggered by the earthquake. The wave heights of the northern coast 
of Taiwan are then used as boundary conditions for FLO-2D overland simulation model. 
With this model, the maximum flood depth, the maximum velocity of the tsunami wave 
and the maximum water level rise rate are gotten and used for production of tsunami 
hazard map. The hot spots of assumed scenario can be read from this map and used to 
take suitable measures to reduce the social impact, the loss of life, and properties.
